The City receives its domestic water from groundwater wells and import water from Three Valleys Municipal Water District Connections, which pulls water from the Colorado River and the state water project through Metropolitan Water District of Southern California. The City has nine (9) total groundwater wells with eight (8) currently active, which supply 25% of the City’s annual water distribution. The groundwater and import water is blended at City facilities before being distributed to customers.
The City’s water system operates under seven (7) zones, which are broken down into five (5) billing cycles, and provides service to approximately 8,900 customers. These zones are labeled numerically one (1) through six (6), and the plateau rate. The zones are charged at different rates based on costs to pump to the customer. The plateau rate is charged a special rate and these customers are entered into the plateau rate by agreement. The City’s current water rate structure consists of three components for its bi-monthly payments: (1) a fixed meter charge, (2) charge for pumping, dependent on customer zone, and (3) a commodity charge, which is based on the amount of water used, measured per unit (1,000 gallons). The plateau rate is charged only for two components for its bi-monthly payments: (1) charge for pumping, dependent on customer location, and (2) a commodity charge, which is based on the amount of water used, measured per unit (1,000 gallons).
The City has a collection and conveyance sewer system. The City’s sewer system consists of approximately 112 miles of sewer mainlines and owns and operates two (2) sewer lift stations. The sewer system is connected to the Los Angeles County Sanitation District’s system. The City charges sewer fees at a flat rate of $23.43 per bi-monthly billing cycle (approximately 60 days). Commercial, industrial, and institutional customers are additionally charged $0.20 per unit throughout the bi-monthly billing period, an approximately 60-day cycle.
In 2018, the City Council approved the most recent rate increase of $0.37 on the water volumetric rate and a $4.43 increase on the bimonthly sewer rate.
