Redwood City is looking to expand its use of recycled water, expanding its system in phases to service additional customers and improve what already exists.
In 2010, the city completed a significant portion of the construction for its two tertiary treatment facilities — which filter wastewater to be able to be used for watering plants and flushing toilets, for example — and more than 17 miles of pipelines.
Now, the city is looking to expand the service area east of Woodside Road and within central Redwood City. The next phased area of focus is to the southwest of Highway 101 between Whipple Road and Woodside Road, approximately.
The proposed project includes adding more than 5.7 miles of transmission, distribution and lateral pipelines, according to a staff report. The expansion would enable the city to serve nearly 250 million gallons of recycled water if all potential customers connect to the system.
The existing recycled water service area already includes the northern, eastern and central portions of the city. Construction for this initial phase was completed over five years from 2006 to 2010, and included two 2.2 million gallon storage tanks. Sites served by recycled water include Oracle, the Redwood City Police Station and the Port of Redwood City, among others.
The use of recycled water significantly reduces demands on the potable water supply, according to the city’s website. Rather than go to the Bay, wastewater is given extra tertiary treatment turning it into recycled water.
“Since pumping began in 2007, the Recycled Water Project has helped save hundreds of millions of gallons of drinking water each year,” the city’s website reads.
Expanding the impact of the city’s Recycled Water Master Plan requires an environmental impact report to evaluate the effects of the project. This includes gathering comments from the public who wish to give input on the project’s scope, which is currently underway. The public comment period is open until 4 p.m. Sept. 1.
Written comments for the expanded service work should be emailed to jchapel@redwoodcity.org or mailed to Justin Chapel at 1400 Broadway, Redwood City, CA 94063.
Members of the public who wish to provide comment in person may do so at the public hearing slated for 3 p.m. Aug. 12 at City Hall.
