Sewer Overflow Prevention

Keeping wastewater in the sewers is the job of CCCSD’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.
