Financial Management

Responsible and effective management of funds is a high priority for NapaSan. NapaSan manages its finances in order to provide daily services as well as plan for the maintenance, improvement and expansion of the sewer collection system and wastewater treatment systems.

How Your Fees Are Spent

Your Sewer Service Charge pays for an essential service that most people rarely think about: collecting and treating the wastewater from your property. For most customers, NapaSan doesn’t charge a monthly fee for its services; instead, you’re invoiced once a year through the County’s property tax statement.  However, the Sewer Service Charge is NOT a tax, it is a fee for service. For current and historic Sewer Service Charge rates, visit our Rates & Fees page.


What costs are involved in wastewater collection and treatment? Visit the Sewer Service Charge Allocation page to find out how the funds are allocated by activity through the NapaSan’s annual budget.  


Annual Comprehensive Financial Report


Each year, NapaSan develops an Annual Comprehensive Financial Report (ACFR). The ACFR is then audited by certified public accountants. The report contains an overview of NapaSan and a discussion and analysis of NapaSan’s financial performance during the previous fiscal year (FY). NapaSan developed an ACFR for the first time for FY 10-11; prior to that, we prepared audited financial statements. The ACFR compiles and summarizes complex financial data in an easily understandable format. View NapaSan's ACFR report / audited financial statements here.


Popular Annual Financial Report


The Popular Annual Financial Report (PAFR) is comprised of information from the Annual Comprehensive Financial Report (ACFR), along with information about NapaSan’s activities this past year. It is specifically designed to be readily accessible and understandable to the general public. View the PAFR here.
