Administration Division

The Administration Division is responsible for overseeing administrative tasks, managing finances, and promoting collaboration among affiliated entities in the water industry. Pomona owes its current success to the efforts of past farmers, landowners, and civic leaders who secured underground water rights for the city. This underground water source has been carefully managed as a shared resource, with over three-quarters of Pomona's water coming from subterranean reservoirs. This is thanks to its strategic location near the San Gabriel Mountains and Mount Baldy.

The Water Resources Department's primary goal is to protect and efficiently manage this natural resource for the people of Pomona. We are dedicated to delivering the purest water possible to both residents and businesses in the city.

Engineering Division

The Engineering Division reviews construction plans, performs field construction visits, meets with local residents/developers and issues on a variety of reports about the City's infrastructure. The Division handles the conformation of water treatment methods, design, construction, maintenance and improvement of potable water, wastewater, recycled water, and stormwater infrastructure.

Water Operations Division

The Water Operations Division is dedicated to providing the City of Pomona with the highest quality water and ensuring its safety. Our commitment is to promptly meet the needs of both residents and businesses while maintaining affordability.

To achieve this, we operate with ingenuity by utilizing local sources of groundwater and surface water. Our teams in production, distribution, construction, water quality, and water treatment work together seamlessly to reduce dependence on more expensive external sources. We take great pride in our role and remain dedicated to serving the City of Pomona.

Production Division 

The Production Division is in charge of maximizing locally produced groundwater and locally collected surface water to minimize reliance on more expensive purchased water from Metropolitan Water District (MWD) and Three Valleys Municipal (TVMWD). The goal is to have the highest quality water supplied upon demand to the City’s customers in an effective and efficient manner at the least cost to the City. Program activities include acquiring and storing sufficient quantities of high-quality water and recycled water to serve residents and businesses. 

Distribution

The Distribution Division provides the maintenance of the City's water distribution system by carrying out scheduled inspections of operations and for the repair of gate valves, pressure regulating valves, meters, and fire hydrants. Distribution provides emergency repair service for broken mains, service lines, fire hydrants, and other distribution system equipment so that the City's water customers have a safe, sufficient and uninterruptible supply of water to meet their varied needs. 

Wastewater

The Wastewater Division operates and maintains a sanitary sewer system that carries wastewater from toilets, showers, sinks, and dishwasher/washing machines and conveys it away from the homes and businesses. 

Treatment

The Treatment Division operates and maintains the City's water treatment facilities, air stripping towers, anion exchange plants. The Team inspects, repairs, and performs maintenance of plant equipment. The Division determines proper dosage of chemicals to ensure that treatment objectives are met and that the delivered water is safe for consumption. These facilities process surface water and groundwater which allows Pomona to provide water at a much lower rate to its customers. 

Water Quality Control

The Water Quality Control Division ensures the highest quality of delivered water and the proper operation of water physical plant facilities by providing cross-connection control, chemical analysis and bacteriological testing, as well as reporting on the quality of the City's water to its customers and various governmental agencies. A primary goal is that the City's water utility remains in compliance with the Environmental Protection Agency (EPA) and the California State Water Resources Control Board, Department of Drinking Water.
