Report on May 13, 2008 Discharge Event

On May 13, 2008 between 12:00 a.m. and 7:00 a.m. the main treatment facility located at 2001 Paradise Drive released 67,500 gallons of water into Raccoon Straits in the usual method.  However, the discharged water had undergone only Primary treatment and Disinfection, not the usual Secondary treatment.  Under our NPDES Permit, releasing water with only primary treatment is allowed only during extreme wet weather.  Therefore, the District immediately notified the State Office of Emergency Services, Regional Water Quality Control Board, Directors of Environmental Health, Marin County Department of Health Services and the County Public Health Officer.  Within thirty minutes of reporting, warning signs were placed along the Bay notifying the public to stay out of the water.


Proposed 2010-2014 Sewer Rate Increases

Sewer Service Charge Increase Proposed to Ensure Continued Public Health and Environmental Protection

Although wastewater collection and treatment is a service we all rely on many times each day, it works so well that most of us never stop to think about it.

But now, a sewer service charge increase is needed, and we are working to inform our customers about it. Without the increase, the District will not be able to pay for critically needed upgrades, increasing the risk of having to pay far more to regulators for not complying. In the event of a spill, there could be astronomical fines, and potential damage to the environment and public health.

Although we have taken every reasonable step to lower costs and stretch funds, it has been determined that rate increases are necessary to cover the costs of the upgrades.
