The Wastewater Division operates and maintains the City’s wastewater system, which consists of 9 lift stations, 18 pumps and over 50 miles of sewer mains. The lift stations run in an automatic mode 24 hours per day, 365 days per year. The Wastewater personnel physically inspect and verify proper operation of each lift station several times each week. The stations liquid levels are also monitored remotely. Other responsibilities include bi-annual cleaning of the sewer main pipelines using a high pressure water cleaning truck (some lines are on an increased frequency cleaning schedule), and cleaning specific sewer laterals that have root problems caused by City trees. Lift stations are electrically and mechanically checked out in detail by an outside contractor semi-annually.
The portion of the City sewer system west of Sepulveda Boulevard flows to the City of Los Angeles’ Hyperion Treatment Plant. The portion of the City sewer system East of Sepulveda flows to the Los Angeles County Sanitation Districts Treatment Plant in the City of Carson.
Wastewater employees spend 20% of their time working with Storm Drain Infrastructure.
