Supervisors Consider Mill Valley/Marin County Sustainable Water Pilot Project

Marin county will explore a collaborative graywater project, a pilot program focusing on sustainable water supply choices to address worsening drought, at the Marin County Board of Supervisors Tuesday.

Supervisors Consider Mill Valley/Marin County Sustainable Water Pilot Project

Under a proposed collaboration, the County of Marin would ramp up promotion of graywater systems and other practices in a sustainability effort conveniently timed to address worsening drought conditions. 

On Jan. 28, the Marin County Board of Supervisors will consider authorizing participation in the  Mill Valley/Marin County Sustainable Water Pilot Project in conjunction with  WaterNow, a nonprofit dedicated to promoting sustaining water technology. The program’s goal is to demonstrate the potential to save water, conserve energy, lower water bills, enhance economic development and increase water supply security.

Graywater is often defined as household wastewater that does not contain serious contaminants.Most of it is generated by baths, showers and clothes washers. Wastewater generated by toilets, kitchen sinks and dishwashers is called blackwater.

“Given our current drought conditions, this collaboration could not be more timely,” said Marin County Board of Supervisors President Kate Sears. “Graywater and water capture systems allow us to use water more efficiently and be better stewards of our water and energy resources. I’m excited about the launch of this pilot project.”

Other participants are the Marin Municipal Water District, the City of Mill Valley, the Tamalpais Community Services District and the Marin Builders Association.

The Board of Supervisors advanced the County’s interest in encouraging water conservation in 2011 by adopting local regulations that allow residential property owners to obtain County approval for graywater systems without the time and expense of a conventional permit review process. More recently, the County  Community Development Agency has ramped up efforts to actively promote the benefits of graywater and the relative ease in which consumers may install and use simple graywater systems for outdoor irrigation.

The Sustainable Water Supply Project would be led by WaterNow, and the County’s role would focus on helping identify priorities and needs, providing data, securing resources, identifying new partners and promoting the effort.

The Board meeting starts at 10 a.m. in Suite 330 of the Marin County Civic Center. To learn more about the project, contact WaterNow Executive Director Cynthia Koehler atck@waternow.org or 415-515-0511.
