1. OPERATING CONTEXT                                                            

Companhia de Saneamento Basico do Estado de Sao Paulo - SABESP has for its      
corporate object the operation of public water and sewer systems in the State   
of Sao Paulo, through concession of these services, to a comprehensive network  
of home, commercial, industrial and government customers. The Company also      
supplies bulk water to municipalities in the Metropolitan Region of Sao Paulo   
that are not provided with their own water production systems.                  

The company provides water and sewer services in 322 municipalities of the      
State of Sao Paulo, upon concession therefrom. Substantially all the            
concessions are for a term of 30 years, one of them to expire in 2004 and the   
remainder, between 2005 and 2029. The concessions may be automatically renewed  
for equal periods as those of the initial contracts, unless the relevant        
municipalities or SABESP shall otherwise decide at least six months before the  
concessions expiration dates.                                                   

The company is not provided with a formal concession for supply of water and    
sewer services in the city of Sao Paulo, which answers for most of the          
services revenue, as well as in other 43 municipalities in the State of Sao     
Paulo, operating in these cases under a public deed of authorization. Except    
for the city of Santos, none of these municipalities has a significant          
population. The company understands that it has the right to provide such       
services based, among other aspects, on its possession of the water and sewer   
services serving the city of Sao Paulo and the other municipalities and on      
certain succession rights resulting from the merger that generated SABESP.      

2. PRESENTATION OF THE FINANCIAL STATEMENTS

6. ACCOUNTS RECEIVABLE FROM SHAREHOLDERS                                        

These refer to complementation of retirement and leave funds paid by the        
company to former employees of state-owned companies that were merged for the   
organization of SABESP. These funds shall be recovered by SABESP from the       
State Government, which is liable for such obligations, in conformity with      
State Law n(0) 200/74. Such credits, which on September 30th represented R$     
58,945 thousand, shall be included in the State of Sao Paulo Government's       
Budget Proposal, as approved by the State House of Representatives.             

On December 11, 2001, an "Instrument of Acknowledgment and Consolidation of     
Obligations, Payment Commitment and Other Covenants" was executed, as           
described in note 15, in which the State acknowledges to owe the amount of      
R$320,623 thousand, corresponding to the history balance of these liabilities   
on November 30, 2001. In relation to such agreement, the first installment      
thereof being due within 210 days after its execution, the amount of R$33,750   
thousand is recorded in the current assets, in the item "Accounts Receivable    
from Shareholder" and the balance is recorded in the long term assets, in the   
item "GESP Agreement".                                                          

The calculation and payment of the 1st installment, in accordance with clause   
11, is pending conclusion of the legal works being developed by the State       
Department of Finance and the Office of the State Attorney General, as          
required for verification of the amount relating to the payment of the pension  
supplementation.

Depreciation:                                                                   

Depreciation is calculated at the following annual rates: buildings - 4%;       
interceptors and networks - 2%; machinery and equipment - 10%; water meters -   
10%; vehicles - 20%; computer hardware - 20%; building connections - 5% and     
office furniture - 10%.                                                         
Amortization of intangible assets is performed pursuant to the terms of the     
concession contracts for the relevant municipalities.                           

(i) Works in progress                                                           

Estimated expenses as from October, 2002, until 2007, referring to works        
already agreed to, are of about R$ 1,006 million.                               

(ii) Retirement of permanent assets                                             

The company retired assets in this quarter in the amount of R$ 2,157 thousand   
(R$ 4,173 thousand - 3rd quarter of 2001), relating to the group of operating   
properties, due to obsolescence, withdrawal from operation and thefts.          

(iii) Expropriations                                                            

As a result of the performance of priority works relating to the water and      
sewer systems, certain expropriations and easements were required in third      
parties' properties, which were conducted pursuant to the pertinent             
legislation. The owners of such properties will be indemnified in accordance    
with out-of-court settlements or through judicial proceeding.                   
SABESP's Legal Department estimates that the amount to be disbursed as from     
the fourth quarter of 2002, without a scheduled date for the actual             
disbursement, is approximately R$189,000 thousand, which shall be made out of   
own resources. The properties that are object of such processes shall be        
recorded in the fixed assets after the operation is closed.                     

(iv) Tax effects on assets revaluation                                          

As permitted by CVM Instruction 197/93, the Company failed to book a provision  
against (deferred) tax effects on gains from revaluation of fixed assets        
occurred in 1990 and 1991. If such effects had been recorded, the amount not    
realized until September 30, 2002 would be R$ 580,517 thousand. In the period   
from January to September, 2002, the realized amount was R$ 72,486 thousand.

The amount of R$238,779 thousand, as shown above, was ascertained at the time   
of the adhesion to the Refis. After that date, charges were incurred in the     
amount of R$51,584 thousand and amortizations were effected in the amount of    
R$141,402 thousand.                                                             
Note: Fines and interests as above mentioned were already included in payment   
settlements executed in previous periods.                                       

The Company adhered to the Refis with the sole purpose of having the payments   
of debts previously agreed with the Federal Revenue Service once again divided  
into installments.                                                              

The Company selected the system of alternative payment into equal installments  
for a period of 60 months, added by TJLP - long term interest rate, which       
installments are not subject to the payment limit based on an invoicing         
percentile. The Management's option for adhesion took into consideration,       
specially, the reduction in the interest rate applicable to the referred        
debts, changing from the Selic rate, that governed the adjustments of           
agreements in effect until February 29, 2000, to the TJLP rate. The financial   
gain, at present value, if calculated with basis on the above described terms,  
was not acknowledged in accounting terms in satisfaction of the Brazilian       
accounting standards.                                                           

On March 31, 2000, the accumulated balance of the Social Contribution Negative  
Basis was R$28,506 thousand, which was not used for payment of interests and    
fines. No accrued balance existed for Tax Losses as of this date.

Adjustments were not effected as a result of the adhesion to the Refis. The     
amount of the installments paid before the adhesion to the Refis was            
approximately R$ 7 million/month, falling to R$ 4 million/month.                

Lands in the amount of R$249,034 thousand were recorded in the operation, as    
guarantee of payment of the referred debts.                                     

The option for the Refis requires mandatory regular payment of taxes and        
contributions, as provided for in the pertinent legislation.                    

Up to now the company has not been granted homologation by the Federal Revenue  
Service. Control has been made through statements of account, where the         
balance shown by the Federal Revenue Service is lower by approximately R$30     
million.

The company has requested to fully deduct negative calculation basis of the     
social contribution and tax losses, without the 30% limit provided for in Law

and tax losses in the amount of R$ 1,141,189 thousand, on which the             
corresponding tax credit was accrued in the amount of R$ 129,774 thousand and   
R$ 285,297 thousand, respectively.                                              
In compliance with CVM Deliberation n(0) 273/98 and CVM Instruction n(0)        
371/02, the realization of credits relating to tax losses and negative          
calculation basis of the social contribution based on a budget projection

and complementary monetary adjustment (difference between the IPC - Consumers   
Prices Index and BTNF - National Treasury Tax Bonds, to be realized in the

(i) Cofins and Pasep Law 9.718                                                  
In an Ordinary Action, with request for advanced protection, the company is     
challenging in court the system provided for by Law no. 9718/98, which          
broadened the calculation basis of the contribution to the Social Security      
Financing - COFINS and to the Public Servant Equity Formation Program - PASEP   
and increased the COFINS rate. The request for advanced protection was granted  
on June 11, 1999, without requirement of deposit in court.                      
The calculation difference ascertained, pursuant to the current law criteria    
and the amounts actually paid, calculated in accordance with the previous law,  
from 1999 to 2002, totals R$ 153,808 thousand and was recorded in the current   
liabilities.

In July, 1991, an Ordinary Annulment and Declaratory Action was filed through   
proceeding no. 91.0663460-5, requesting the Finsocial debts to be declared      
null and void and the Sabesp's obligation to contribute to the Finsocial to be  
terminated.                                                                     
Court deposits were effected at the rate of 2%, referring to the periods from   
April 1991 to April 1992, and on August 30, 1994 the withdrawal of 75% of such  
deposits was authorized. The remainder 25%, corresponding to the rate of 0.5%,  
was kept as a court deposit and a provision also booked therefor. Upon the      
Federal Supreme Court - STF having acknowledged the constitutional basis of     
the Finsocial assessed on gross revenues of solely service companies, the       
company paid, on July 26, 2002, the amount of R$ 57 million, corresponding to   
1.5% of the total outstanding debt and requested the conversion into income on  
the Federal Revenue Service's behalf, of the total amount deposited in court,   
corresponding to 0.5%, thus concluding the litigation referring to proceeding   
n(0) 91.0663460.5.

The company, based on a joint analysis with its legal advisors, has booked a    
provision for contingencies deemed to be enough to cover probable losses        
arising out of court judgments against it, in the amount of R$ 127,642          
thousand (Jun/2002 - R$ 122,339 thousand).                                      

Additionally, the company has been pursuing several lawsuits, for which its     
legal counsels evaluated that possible losses would be in no material amounts.  
However, due to the progress of some of these proceedings, at a stage of final  
judgment recently, which will result in disbursements of about R$ 7,000         
thousand, the counsels reevaluated their positions, and now consider the        
possibility of defeat for the company as being likely to occur, specifically    
for some lawsuits in a final execution stage, in spite of the fact that         
favorable judgments have already been obtained by Sabesp for one third of the   
lawsuits in the same nature.                                                    

The company has booked a provision in the amount of R$30,000 thousand in order  
to cover payments relating to lawsuits for which a defeat is probable, in the   
quarter ended as of September 30, 2002, considering only final judgments        
against the company. However, the company will follow-up the evolution of the   
existing lawsuits and conduct detailed studies as for the amounts involved.     
Thus, in case other lawsuits may be identified to fall under the same           
situation, that is, with a remote possibility of success or requiring a review  
of the booked provisions, the respective adjustments shall be effected.         

(c) Lawsuits                                                                    

The company is a party to lawsuits and administrative proceedings referring to  
environment, tax, civil and labor proceedings, which are deemed by our legal    
advisors to be likely to be successful/defeated and which are not shown in      
company's accounting records. The amount ascribed to these proceedings          
represents R$ 98,844 thousand on September 30, 2002 (Jun/2002 - R$ 20,859       
thousand).                                                                      

12. PENSION AND ASSISTANCE PLANS                                                

The company sponsors Fundacao Sabesp de Seguridade Social - SABESPREV, an       
entity organized in August, 1990 with the main purpose of administering         
SABESP's complementary pension plans and assistance program for its employees.  

The Company's monthly contributions, related to the pension plan - defined      
benefit, correspond to 2.10% from the company and 2.10% from the participants.  

The participants' contributions are mentioned above in their average value,     
since the amount discounted as contribution varies in function of the salary    
range, from 1% to 8.5%. The Company's contribution includes the liability       
undertaken with reference to periods preceding the organization of the          
SABESPREV.                                                                      

The assistance program, which comprises elective, free-selection plans, is      
also maintained by contributions from both sponsor and participants, which in   
the fiscal year were as follows:                                                

. Company's contributions: 6.21% in average, on the payroll;          

. Participants' contributions: 3.21%, on base salary and bonus,       
corresponding to an average

of 2.25% of the gross payroll amount                                            

The company is changing the Defined Benefit Plan into a Defined Contribution    
Plan, with the purpose of reducing future risks for the Institution, offering   
a more modern and flexible plan to its employees.                               

13. BENEFITS TO EMPLOYEES                                                       

In order to meet the provisions of Resolution CVM no. 371, of December 13,      
2000, we inform below the amounts calculated for pension and retirement         
benefits granted and to be granted to which the employees shall be entitled     
after years of service.                                                         

On December 31, 2001, based on an independent actuarial report, calculated in   
accordance with the Projected Credit Unit method, SABESP had a net actuarial    
commitment of R$ 266,074 thousand representing the difference between the       
present value of the Company's obligations in relation to employed, retired     
and pension participants and that of the guarantee assets, as shown below:

                                                         -------

The company's contribution includes the undertaken liability referring to       
periods before the organization of SABESPREV, which is payable until February   
2011. Such liability, defined pursuant to an actuarial calculation, is R$       
9,237 thousand, and is recorded in long term liabilities.                       

For year 2002, we have estimated the following expenses to be incurred:

The liabilities and expenses ascertained through the actuarial calculation      
were obtained by adopting the following criteria :                              

Economic Hypothesis                                                             
- Nominal discount rate - 10.5% p.a.;                                           
- Estimated asset return nominal rate - 10.5% p.a.;                             
- Future salary growths - 4.75% p.a.;                                           
- Social security benefits and limits growth - 2.5% p.a.;                       

Note - The economic hypothesis consider a long term inflation of 2.5% per       
year.                                                                           

- Number of active participants on December 31, 2001 16,859                     
- Number of inactive participants on December 31, 2001  4,442                   

The evaluation of SABESPREV's funding plan is carried out by an independent     
actuarial expert, whose premises are different from those applied for purposes  
of calculating benefits to employees, as provided for in Resolution CVM no.     
371, substantially as for the actuarial calculation method (CVM no. 371 -       
capitalization and SPC - Complementary Retirement Service - mixed) and          
discount rate (CVM no. 371 - 10.5% nominal and SPC - 6.0% actual).              

Thus, the eventual deficit ascertained on December 31, 2001, in accordance      
with the projected credit unit method shown above, which may reflect a          
technical deficit in the method being adopted by Sabesprev's Plan, shall        
result in additional financial contributions.

Clause 2 of the Memorandum of Understanding provides for that: "The State

SABESP shall be settled upon use of dividends distributed by the company; II -

dates, being further undertaken to take any and all actions of an               
administrative nature in order to avoid late payments by its agencies and       
entities.                                                                       

15. FINANCIAL INSTRUMENTS                                                       

(a) Market value of financial instruments                                       

Market values of the main financial instruments of the Company are close to     
book values, as follows:                                                        

                                                        In thousand R$

Investments in securities                        442,005         675,148

                                        ==========      ==========

Market values were calculated pursuant to the present value of these financial  
instruments, considering the interest rate adopted by the market for the risk   
operations and similar terms.                                                   

(b) Credit risk concentration                                                   

A substantial portion of the Company's sales is quite well spread over a        
great number of customers. In the case of such customers, a minimum credit      
risk exists due to the large portfolio and the control procedures, which        
monitor such risk.                                                              
Doubtful credits are properly covered by a provision in order to face eventual  
losses upon realization thereof.                                                

(c)      Foreign currency                                                       

Foreign currency transactions consist of financing intended to specific works   
of improvement and enhancement of water supply and sewer collection and         
treatment systems.

The Municipalities of Diadema and Maua terminated the concessions of water      
supply and sewer collection services in the beginning of 1995.                  

In December, 1996 the Company filed an action for indemnity seeking repayment   
of the investments carried out during the effective term of the concession      
agreements.                                                                     

Although not yet repaid for the respective amounts, the Company continues       
supplying treated water, in bulk, to the mentioned municipalities, which        
currently operate the water and sewer systems.                                  

The residual book value of fixed assets related to the Municipality of          
Diadema, written-off in December, 1996, was R$ 75,231 thousand, and the         
balance of indemnity and other credits receivable from the municipality, in     
the amount of R$ 62,876 thousand, is recorded in the long term assets in the    
"Indemnities receivable" account .                                              

The residual book value of fixed assets related to the Municipality of Maua,    
written-off during fiscal year 1999, was R$ 103,763 thousand, and the           
outstanding indemnity, in the amount of R$ 85,918 thousand, is recorded in the  
long term assets, in the "Indemnities receivable" account.                      

Both cases are currently under court discussion; however, it is the opinion of  
the legal consultant in charge for the conduction of the lawsuits that a        
favorable judgment may be expected by the Company.

Sabesp posted net operating revenue of R$ 963.3 million and EBITDA of R$ 480.6  
million in 3Q02. The final result in the period, a net loss of R$ 663.6         
million, was strongly influenced by the effect of the Brazilian Real            
depreciation on the Company's dollar-denomin                                    

2.    Operating Revenue - growth of 9.5% in retail volume billed                

Net operating revenue grew by R$ 110.9 million or 13.0%. This is the result of  
a 9.5% increase in retail billed volume and an 8.22% increase in fees           
effective August 8, 2002, with an effect on revenue during only half the        
quarter.

* 3Q01 values differ from those reported in previous releases due to small      
adjustments made between residential and commercial consumers in the        
Metropolitan Area.                                                          

Total retail volume billed in millions of cubic meters (water+sewage)           
represented a growth of 9.5% year-on-year between 3Q02 and 3Q01.

As we pointed out in last quarter's comments, the end of electricity rationing  
allowed a gradual return to normal customer consumption habits, mainly in       
relation to residential users. Another factor that contributed to the increase  
in consumption was an atypical winter, with temperatures above historical       
averages.                                                                       

3.    Costs, Administrative and Selling Expenses

3.1. Salaries and Payroll Charges                                               

The Salaries and Payroll Charges group reported a 22.6% increase or R$ 41.0     
million. This increase is mainly due to the following factors:                  

(a)  Collective bargaining agreement, resulting in wage increases of 8.0% in    
   May 2002; a 2.2% increase in the number of employees (401 employees), and
Compensation for Competence -

whereby up to 1% of payroll was used to regularize positions and      
respective salaries (effective June 2002) and also up to 1% for career
promotions (effective July 2002);                                     

(b)  Provision for profit sharing, amounting to R$ 8.9 million recorded in      
3Q02;                                                                 

(c)  Provision for retirement benefits, amounting to R$ 3.8 million, resulting  
from the allocation, as of 2002, of current costs relative to an      
 actuarial liability provision relating to the employees who are members
of Sabesprev's defined benefit pension plan, in compliance with CVM   
Deliberation 371/00 (Section 85 of NPC 26 of IBRACON);                

(d)  FGTS (Government Severance Indemnity Fund for Employees) amounting to R$   
1.5 million, representing an increase in the rate of employer         
contributions to the fund (from 8.0% to 8.5%) and the increase in the 
severance indemnity on the FGTS (from 40% to 50%), according to the   
Complementary Law 110/01 of June 29, 2001 (effective October 2001).   

3.2. General Supplies                                                           

The General Supplies group showed a 21.7% increase, or R$ 3.4 million, due to   
the maintenance performed in the systems and networks, the maintenance of       
buildings and facilities and the increase in the fuel and lubricants item, as   
a consequence of the price increases that occurred in the comparable period.    

3.3. Treatment Supplies                                                         

The Treatment Supplies group showed a 26.4% or R$ 3.3 million increase, as a    
result of the low quality of raw water sources, and consequently resulting in   
increased demand for treatment supplies and coagulants. Another factor is       
linked to the substitution of certain treatment supplies, in some cities in     
the interior of the State of Sao Paulo, such as, for example, the substitution  
of sodium hypochlorite for chlorine gas.                                        

The chart below shows the impact from cost increases on the main chemical       
supplies used by Sabesp in its treatment process:

3.4. Third-party Services                                                       

The Third-party Services group reported a growth of R$ 18.9 million or 26.4%.   
The main changes identified under this item are:                                

(a)  Maintenance of residential water connections, a growth of R$ 4.8 million,  
  relating principally to services for the optimization of measuring water
volumes supplied by Sabesp to major consumers;                        

(b)  Credit recovery, a growth of R$ 3.4 million, due to the greater use of     
outsourced services for the recovery of past due payments;            

(c)  Networks Maintenance, a growth of R$ 1.9 million, caused mainly by the     
  increase in services of Clearing Sewer Networks and Branch Sewers in the
Metropolitan Area of Sao Paulo and in the Municipality of Braganca    
Paulista;                                                             

(d)  Systems Maintenance, an increase of R$ 1.5 million, caused by the          
maintenance, conservation of installations and recovery of power pump 
sets in several Company units;                                        

(e)  Software Maintenance, an increase of R$ 1.1 million, relating to the       
adaptation, maintenance and expansion of Sabesp's IT resources.       

3.5. Electric Power                                                             

The electric power group grew by 45.0% or R$ 21.9 million, due to the           
following factors:                                                              

(a)  Electricity fee increases authorized by the electric power regulatory      
agency, ANEEL, for the several Electric Power utility concessionaires 
that provide services to Sabesp;                                      

(b)  Increase in Sabesp's electric power consumption. In 3Q02 the consumption   
   was 491,129 MWh, 14.0% higher than consumption in 3Q01, which was 430,884
  MWh (as a consequence of the electric power rationing that occurred from
June 2001 to the beginning of 2002);                                  

(c)  The Surcharge created by provisional measure No. 14 of 12/21/2001 and Law  
No. 10,438 of 04/26/2002, in the form of an additional fee increase of
 7.9% effective January 2002 and to be in force for an average period of
six years;                                                            

(d)  Charging of ECE - Emergency Capacity Fee, it was initiated in March 2002   
 and it was changed through ANEEL Resolution No. 351, effective June 28,
2002. The ECE represented an impact of 4.12% in total electric energy 
costs for the 3Q02.                                                   

3.6. General Expenses                                                           

The General Expenses group fell by 67.0% or R$ 41.3 million, mainly as a        
result of the provision for tax contingencies, relating to the recording of     
Proceeding No. 91.0663460-5 - Finsocial, which occurred in 3Q01, in the amount  
of R$ 38.3 million.

4.    Financial Expenses and Foreign Exchange Loss                              

(a)    Financial Expenses                                                       

The Financial Expenses group grew R$ 87.9 million or 45.8%, mainly due to:      

   o    Interest, fines and late fees on domestic loans and funding, with an
increase of R$ 22.0 million, resulting from the increase of 
debentures - 5th issue, which took place in April 2002;     

  o    Interest, fines and late fees on foreign loans and funding, with an
      increase of R$ 10.9 million. In 3Q02, as a consequence of the Real
  depreciation, the balance due is higher when compared to 3Q01,
      causing an increase in interests, especially of Eurobonds and BID,
    partially offset by a decrease due to the full settlement of the
     loan from Westdeutsche Landesbank Girozentrale, in February 2002;

o    Other financial expenses, an increase in the amount of R$ 21.6   
million, mainly arising from interest on tax proceedings;   

o    Provisions, an increase of R$ 33.5 million arising from the      
provision for legal proceedings.                            

(b)      Foreign Exchange Loss                                                  

Foreign Exchange Loss was up by R$ 605.9 million or 124.5%, due to the 36.9%    
depreciation of the Real against the dollar in 3Q02 compared to 15.9% in 3Q01,  
with a higher impact on BID loans, Eurobonds and Deutsche Bank Luxembourg.      

5.    Operating Indicators                                                      

The Company continues to expand its services as illustrated by the trend in     
the number of water and sewage connections in the chart below:

6. Funding                                                                      

Policy                                                                          

Since Brazil adopted a floating foreign exchange rate policy in January 1999,   
the Company's debt management has been guided by three main courses of action:  

o    the lengthening of the debt maturity profile;                              

o    priority given to local currency funding as a substitute to credit         
operations in foreign currency. The exception to this rule is credit  
operations with multilateral financial institutions such as IDB and   
bilateral organizations such as JBIC (Japan Bank for International    
Cooperation);                                                         

o    priority given to lower cost credit operations, such as those provided by  
  the BNDES (the Brazilian National Development Bank) and CEF (the Federal
Savings and Loan Bank), whenever possible.                            

In this context, the Multi-year Budget Plan (2002-2006) foresaw:                

o    a single debenture issuing in 2002, already concluded;                     

o    only two foreign currency operations, but with very long maturities (25    
 years) and low costs, with the guarantees of both the Federal and State
of Sao Paulo treasuries: (a) IDB: US$ 200 million (executed in July   
2000); and (b) JBIC: US$ 150 million (currently in the final phases   
before execution);                                                    

o    BNDES: R$ 400 million, indexed to the TJLP (the long-term interest rate)   
plus 3% p.a., with a 10-year term and a 3-year grace period (R$ 240   
million already executed in July 2002);                               

o    CEF using FGTS resources: up to R$ 520 million with a 10-year term and     
interest at TR (reference rate) plus 10.5% p.a. for investments in the
sewage segment and 12.0% in the water supply segment.                 

7.    Funding in 2002                                                           

The Company concluded its 5th issue of simple debentures in April 2002, in the  
amount of R$ 400 million, represented by 40,000 debentures at a face value of   
R$ 10 thousand each.                                                            

The issue was divided into 2 series, the first consisting of 31,372 debentures  
indexed to the CDI (interbank deposit certificate) rate plus a spread of        
1.85%. The second series comprised 8,628 debentures indexed to the IGP-M plus   
interest of 13.25% p.a. The interest on the first series will be paid           
quarterly, and on the second, annually. The debentures' final maturity will be  
in March 2007.                                                                  

Sabesp signed with the BNDES and four more private banks, on August 8, 2002, a  
financing contract worth R$ 240 million representing the domestic portion of    
the funding for the Tiete Project - Phase II.                                   

Sabesp is negotiating financing agreements for water and sewage works, with     
FGTS funds, whose manager is Caixa Economica Federal (the Federal Savings and   
Loan Bank), in the amount of R$ 244 million, with disbursements starting in     
early 2003. The striking characteristics of this operation are its low cost     
(TR - Central Bank reference rate - plus 10.5% for sewage and 12% for water)    
and long-term amortization (10 years).

Finally, the talks for the execution of the financing agreement for the Santos  
Coastal Plains Cleanup project with the Japan Bank for International            
Cooperation - JBIC are in their final stages, and it has already received the   
approval of the Japanese Government for inclusion in that country's Fiscal

September marks the end of the dry season and of the hydrological year (Oct/01  
to Sep/02) and the water supply has been kept at steady levels. Even with       
rainfalls below average for the month of September, the accumulated rainfall    
index in the present hydrologic year is close to historical averages.           

As we can see in the above chart, as the dry season is over, the available      
volumes are comfortable (Cantareira and Rio Claro have more than double and     
Alto Cotia more than triple the volume they had in the same month in 2001),     
thus ruling out the risk of rationing in the next summer.

Capital Markets and General Information                                         

In April 2002, SABESP's shares began trading on the "New Market - BOVESPA",     
following the company's compliance with the rigorous Corporate Governance       
parameters required by this segment of the market.                              

In May 2002, the Sao Paulo State Government sold 4.78 billion of its holdings   
in SABESP shares, through a public offering (including a Green Shoe of 165      
million shares), representing 16.8% of the capital stock. This increased the    
company's free float to 28.5%. The public offering was directed at both         
domestic and international investors, while the company's ADR was listed on     
the New York Stock Exchange as from May 10, 2002, under the "SBS" ticker.       

On June 3, 2002, the Sao Paulo City Council approved Law 13,370, which under    
article 1 makes it mandatory for all existing buildings to be connected to the  
public sewage system in regions where such a network already exists. This law   
is in line with SABESP's targets for optimizing the use of the sewage network   
already installed by the Company.                                               

On August 1, 2002 and pursuant to the provisions of CVM Instruction 358 of      
January 03, 2002 and in accordance with Article 28 of the Regulations for the   
Tariff System approved by State Decree Law 41,446 of December 16, 1996,         
Companhia de Saneamento Basico do Estado de Sao Paulo - SABESP announced that   
the tariffs and other conditions in force for the supply of water and/or        
sewage collection will be increased from August 7, 2002. The price adjustment   
will be 8.22% for all categories of use and consumer types with the exception   
of the following items, which shall remain with their present values: (a)       
tariffs falling into the social residential use and slum category; (b) special  
supply to vessels on the coastal region (Litoral Norte and Baixada Santista);   
(c) supplies of water using tankers; and (d) tariffs for firm demand            
contracts.                                                                      

The full announcement can be found in Sabesp's website www.sabesp.com.br and    
was also published in the State of Sao Paulo Official Gazette, August 3, 2002   
edition.

-------------------------------------------------                               

November 27, 2002                                                               

To the Management and Shareholders of                                           
Companhia de Saneamento Basico do Estado de Sao Paulo - SABESP                  

1.   We have made a limited review of the accounting information supplied in    
 the Quarterly Report - ITR, issued by Companhia de Saneamento Basico do
Estado de Sao Paulo - SABESP, for the quarterly periods ended on      
   September 30 and June 30, 2002 and September 30, 2001, prepared under the
responsibility of the Company's Management.                           

2.   Except for what is mentioned in paragraph 3 below, our review was          
conducted in accordance with the specific standards established by the
Brazilian Institute of Independent Auditors - IBRACON, in conjunction 
with the Federal Accountancy Board and consisted particularly of: (a) 
 inquiries and discussions with the management staff responsible for the
 accounting, financial and operating areas of the company with regard to
 the major procedures adopted in the preparation of the quarterly report
and (b) review of the relevant information and subsequent events which
have or may have significant effects on the financial position and    
results of the Company's operations.                                  

3.   As referred to in Note 11 (b), the company has pursued several civil       
   lawsuits within a legal scope, which are evaluated by its counsel subject
 to probable, possible and also remote losses, for which the company has
booked a provision of R$ 30 million in the quarter period ended on    
September 30, 2002. It has not been possible for us, under the        
  circumstances, based on the evaluations made and studies conducted up to
 the present date by the company's management and its legal counsels, to
   arrive to any conclusion as to the estimated amount of final loss for the
company, considering all the lawsuits being pursued.                  

4.   Based on our limited review, except for the eventual relevant effects      
that may result from the matter mentioned in paragraph 3, we are not  
 aware of any relevant change that should be made to the above mentioned
quarterly report to make it comply with the accounting principles     
provided for in the Brazilian corporation law applicable to the       
 preparation of a quarterly report in accordance with the regulations of
the Brazilian Securities and Exchange Commission (CVM).
