Plumbing in Torrance
Torrance Municipal Water's 2025 Annual Water Quality Report gets 32 percent of its drinking water from three operating wells in the West Coast Groundwater Basin plus a groundwater desalination project. The rest is imported by the Metropolitan Water District from the Colorado River and Northern California. The same report discusses locating lead service lines for replacement, so read it if you're asking about yours. EPA's record gives the system number as CA1910213, named Torrance-City, Water Dept., purchased surface water, with 106,183 people counted across the system.
State law has had lead-line deadlines for years. Health and Safety Code 116885 gave community water systems until July 1, 2018 to inventory known lead user service lines. By July 1, 2020 they also had to give the State Water Board a replacement timeline and findings on lines of unknown material. Torrance splits plumbing from the rest. Its Building and Safety FAQ lists separate building, electrical, mechanical and plumbing permits, and the plumbing permit covers pipes, fixtures, water heaters and sewer work.
That division is part of Community Development. By build year, the middle of Torrance's housing sits at 1964 (Census Bureau, 2020 to 2024 sample), a midpoint across all units.
