Private Sewer Lateral Ordinance

In 2013, the California Regional Water Quality Control Board (Water Board) ordered the Ross Valley Sanitary District (RVSD) to fix old, cracked sanitary sewer pipes. Many pipes are in need of repair to prevent the infiltration of rainwater, which can overwhelm the wastewater collection system and treatment plant, leading to sanitary sewer overflows in the community or discharges of partially treated wastewater into the San Francisco Bay. 


The Water Board's order compelled RVSD to phase in a Private Sewer Lateral Ordinance (PSL) beginning in June of 2014. Affected property owners must obtain certification from RVSD that their PSLs are leak-free.
