Administration Division

The Administration Division provides administration, fiscal control, and inter-agency coordination with affiliates in the water industry. Pomona today benefits from the decisions of forward-thinking farmers, landowners, and civic leaders in the past who secured underground water rights for the City of Pomona and managed such as a shared resource. Pomona receives over 3/4ths of its water from underground reservoirs, a precious natural resource derived from its location adjacent to the San Gabriel Mountains and Mount Baldy. The mission of the Water Resources Department is to protect and manage this natural resource for the people of the City of Pomona and to provide the cleanest water possible to the residents and businesses of Pomona.

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 engineers are available for in-person signatures and meetings by appointment only. Appointments are offered Monday through Thursday, from 1:30 – 4:30 p.m.

Water Operations Division

The Water Operations Division provides safe, high quality water, and delivers this water upon demand in an efficient manner at a reasonable cost to residents and businesses within the City of Pomona. The Division maximizes locally produced groundwater and locally collected surface water to minimize reliance on more expensive purchased water through the efforts of production, distribution and construction, water quality, and water treatment sections.

Production

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.

Environmental Compliance

The Environmental Compliance Division provides policy, guidance, and training to help maintain compliance with environmental laws and regulations, minimize environmental risk and liability, and promote environmental best management practices. The team strives to protect and conserve our natural resources through education, planning, waste reduction, recycling, and pollution prevention. This division is responsible for the management and implementation of the City’s Energy Efficiency goals and projects. Stomwater Pollution Prevention Program, Sewer System Management Plan (SSMP) that includes the Fats, Oils and Grease Control Program, and education on water use efficiency.

Public Health Goals Report

Provisions of the California Health and Safety Code 116470 (b) specify that water utilities with 10,000 or more service connections are required to prepare a special report by July 1, 2019, if water quality measurements have exceeded any Public Health Goals (PHGs). PHGs are non-enforceable goals established by the California Environmental Protection Agency’s (Cal-EPA) Office of Environmental Health Hazard Assessment (OEHHA). The law also requires that where OEHHA has not adopted a PHG for a constituent, water suppliers are to use the Maximum Contaminant Level Goals (MCLGs) adopted by United States Environmental Protection Agency (USEPA). Only constituents which have a California primary drinking water standard, also known as Maximum Contaminant Level (MCL), and for which either a PHG or MCLG has been set are to be addressed.

This report provides information required by law of constituents detected in the City’s water supply between 2016 and 2018 at levels exceeding the applicable PHG or MCLG. Included is the numerical public health risk associated with the MCL and the PHG or MCLG, the category or type of risk to health that could be associated with the constituent, the best treatment technology available that could be used to reduce the constituent level, and an estimate of the cost to install that treatment, if it is appropriate and feasible.
