Water Supply/Quality Reports

Public Health Goals (PHG)

The Public Health Goals Report is a comparison of the drinking water quality provided by the District against the PHGs adopted by the California Environmental Protection Agency, Office of Environmental Heal Hazard Assessment (OEHHA). PHGs are levels that do not pose a significant risk to health and are not regulatory standards. As the OEHHA website states, drinking water standards established by the State are required to be set as close to the corresponding PHG as is economically and technologically feasible. This report details constituents within the District's drinking water which exceed the adopted public health goal and estimates the cost required in order to meet the PHG. This report is updated every three years.

Water Shortage Contingency Plan & Water Conservation Ordinance

The overall principle of the District's Water Shortage Contingency Plan is to reliably meet water demands during water shortages caused by supply interruptions, reductions, or allocations, as well as respond to emergency conditions.

Ordinance 2021-05-05, the District's Water Conservation and Water Supply Shortage Program, establishes the regulatory authority and policies with respect to water conservation and the declaration of a water supply shortage.

Integrated Regional Water Management Plan for South Orange County (IRWM)

The South Orange County Integrated Regional Water Management (IRWM) Plan has been developed from, and coordinates with, existing plans and research documents provided by the participating agencies in a manner that identifies and integrates regional projects to improve water supply, protect water quality, enhance the environment, and provide flood risk management. This Plan establishes a priority ranking to help further regional efforts to investigate the feasibility of, and identify funding for, these projects. Individual projects, however will go through the appropriate environmental review and permitting process as funding is secured.
