Residents
Household Hazardous Waste Collection Facility
In 1997, Central San and Mt. View Sanitary District teamed up to build the first permanent Household Hazardous Waste (HHW) Collection Facility in the county. Residents may drop off household hazardous waste at no charge. Small businesses pay a small fee to dispose of their hazardous waste. In its first 20 years, the facility collected more than 36 million pounds of hazardous waste.
Sewer Overflow Prevention
Keeping wastewater in the sewers is the job of Central San’s Collection System through cleaning, maintenance and repair of 1,500 miles of underground sewer lines. You can help by making sure that your side sewer – the connection from your home to the public sewer – remains free of any blockages.
Construction Zones
Central San strives to ensure that our collection and treatment systems operate in the most efficient manner possible. Through an aggressive capital improvement plan, we initiate projects to upgrade our infrastructure and utilize the most advanced, cost-effective equipment and processes available. As these projects develop, we’ll keep you informed about them through this section of our site.
