DISCUSSION
The Public Works Agency (PWA) is responsible for the daily operations of the City’s drinking water system. The water system comprises of approximately 480 miles of water main, 21 groundwater wells, seven pump stations, 10 reservoirs with a storage capacity of 45 million gallons, four pressure-regulating stations, and seven connection points to the Metropolitan Water District (MWD). The system has an average daily demand of 43 million gallons from its roughly 45,000 service connections.
To maintain compliance with federal and state drinking water regulations, the City uses sodium hypochlorite generation (SHG) units to produce chlorine for potable water treatment. The SHG units utilized by the City meet the water quality requirements established under the City’s Domestic Water Supply permit and are essential for maintaining regulatory compliance; therefore, their ongoing maintenance and reliability are critical to water distribution operations. In addition, this form of sodium hypochlorite generation is recognized as one of the safest methods for introducing chlorine into a potable water system, providing safe and reliable drinking water to residents. These systems require specialized preventive maintenance, system calibration, replacement of proprietary components, and emergency repair services to ensure uninterrupted operation.
