What is a Sewer System?
From plumbing fixtures and appliances, from homes and businesses such as toilets, showers and bath tubs, clothes washers, dish washers, and garbage disposals. Domestic wastewater is discharged from plumbing fixtures and appliances and then flows into the domestic wastewater sewer. The domestic wastewater sewer system is made up of many sewer lines extending from individual lots of land. The line from each lot connects to the sewer line. The city maintains sewer lines located under public streets or alleys that connect to a “trunk sewer”. The main trunks of the sewer end at the City of Santa Maria Wastewater Treatment Plant. All water entering the treatment plant is treated so that approximately 90 percent of the impurities are removed. The rest of the impurities are removed when the treated water is returned back to the groundwater basin through percolation.
