Summary

Helen Quan of the LA County Sanitation Districts summarized the districts' infrastructure (1,400 miles of sewer, 11 treatment plants), processing capacity (~400 million gallons/day), Temple City's wastewater flows, current reuse (about 42 million gallons/day), and the Pure Water Southern California program that could expand potable reuse.

Helen Quan, a public affairs specialist with the LA County Sanitation Districts, described the districts' role serving more than 5.5 million residents across 78 cities, including Temple City, during the council meeting on Aug. 5.

Quan outlined the system's infrastructure—about 1,400 miles of sewers and 11 treatment plants—and said the districts process roughly 400 million gallons of wastewater daily. She said Temple City's wastewater is sent to the San Jose (Whittier) water reclamation plant, which can treat up to 100 million gallons per day for a service population of about 1 million; about 42 million gallons per day are reused across some 130 sites for irrigation, industrial use and groundwater replenishment.

Quan also described the Pure Water Southern California program, which would subject some treated wastewater to advanced treatment for direct potable reuse, reducing reliance on imported water and increasing regional drought resilience. She emphasized the districts' outreach and education programs for schools and community groups and invited residents to contact the districts at local events.

Council members thanked Quan; there were no recorded follow-up questions requiring council direction. The city attorney later noted staff will receive a memo about recent CEQA changes affecting housing and infill projects, which the city will circulate to the council.
