Financial Information

Charleston Water System operations are funded by revenue from rates and fees charged for water and wastewater service, interest-bearing investments, and revenue bond proceeds. Impact fees charged for new connections to our water and sewer systems are an important source of revenue that can only be used for capital improvements related to growth.

We do not receive tax revenue.


Our fiscal year is January 1 – December 31, and the annual budget is approved by our Board of Commissioners. Net balances from operations are held in cash reserves to reduce the amount of future borrowing for capital improvements.  View our 2019 budget.

Debt and Bond Ordinance Requirements

We periodically issue revenue bonds to fund capital improvement projects. Bond issues must be approved by Charleston City Council, and the ordinances that govern the borrowing terms require us to maintain net earnings equal to at least 120% of the annual principal and interest requirement in each fiscal year.
