Investing in clean water - where does your money go?

Wastewater infrastructure is crucial for protecting water quality and economic vitality, and supporting jobs and growth while maintaining our region’s natural assets like beaches, lakes and rivers.
King County's wastewater utility is entirely funded by the ratepayers who invest in our programs and services through their monthly rate and capacity charge bills. We take seriously our obligation to provide the highest levels of service and accountability to our ratepayers.
Bond ratings
Standard & Poor's and Moody’s Investor Services are leading global financial firms that rate corporate stocks and municipal bonds according to risk profiles. In 2012 the firms confirmed the ratings of the Wastewater Treatment Division’s bonds, citing:
- Strong management practices
- Continued positive financial performance
- Solid rate base and large service area
- Commitment to a capital improvement plan
The Moody's rating for the sewer revenue bonds remained at Aa2 while the Standard and Poor’s rating was maintained at AA . These continued favorable credit ratings lower the cost of borrowing by reducing the amount of debt service, which, in turn, reduces impacts to the rate.
Financial statements
The wastewater utility undergoes an annual audit to insure that its annual financial results are fairly stated and that all covenants with the utility’s bondholders have been met. The audited financial results for 2001 through 2011 are here.
