The City of Mill Valley raised its Sewer Service Charges to reflect significant increases in costs that are largely outside of City control. These costs include increased wastewater treatment fees, inflation, increased costs to improve and replace an aging infrastructure, and increased costs to comply with more stringent environmental regulations.

The process of updating the City's sewer service rates began in winter 2011, which included four public meetings and notification of proposed rate increase mailed to every property owner, and concluded on June 20, 2011, with the adoption of Ordinance 1250, increasing rates over the next five years. The current Sewer Service Charge has not increased since 2004. The City has kept rates tremendously low. Such low rates provided very limited revenue stream to make the system-wide improvements needed by our aging facilities. The new rates will provide funding for a sustained replacement program of old sewer pipes, increasing wastewater treatment and disposal charges, and fund a substatially increased and regular sewer pipe maintenance effort.

Effective July 1, 2011, the Sewer Service Charge for a single family residence is $600. The rates for the next five years are summarized below. Rates for businesses and multifamily residential are increased by a proportionate amount.
