Central San 70th Anniversary Open House

Jun 27, 2016 10:39AM ● By Elena Hutslar

To commemorate 70 years of service and show appreciation for its customers, the Central Contra Costa Sanitary District (Central San) will hold an open house on Saturday, July 16. This free, family-friendly event takes place from 10am to 2pm in a park-like setting at their headquarters and treatment plant location, 5019 Imhoff Place, Martinez.  

Attendees will enjoy a variety of fun activities (have you ever raced a toilet?), giveaways, free lunch, educational exhibits, big truck displays (always popular with the kids), tours of the wastewater treatment plant and other facilities, live entertainment by local band PUSH, and much more.   

“This is the first time Central San has hosted a public open house like this, and we’re very excited,” said General Manager Roger Bailey. “In addition to commemorating our 70 years of service and showing people what we do, the open house is a way for us to thank our customers for their support. Whenever they prevent grease from going down the kitchen sink, put disposable wipes in the trash instead of the toilet, or bring chemicals and other hazardous wastes to our collection facility rather than pouring them down the drain, they are helping us to protect public health and the environment. We couldn’t accomplish our mission without their assistance, and we want to show our appreciation by inviting them to our ‘house’ to have a great time and learn more about the services we provide.”

Central San provides wastewater services for more than 476,000 people in central Contra Costa County. They manage 1,500 miles of sewer pipelines, and their treatment plant cleans and disinfects more than 32 million gallons of wastewater every day.

Central San also boasts a Recycled Water Fill Station that provides free recycled water to residential customers for hand-watering lawns, gardens, and landscaping. They also have a Household Hazardous Waste (HHW) Facility that collects, recycles, or safely disposes more than 2 million pounds of hazardous waste each year. While neither facility will be open for business on July 16, due to the open house, attendees can get a rare behind-the-scenes look of the HHW Facility to discover what really happens to all the materials people bring in for disposal!

It’s sure to be an enjoyable event for the whole family. For more information, please go to
