PLANS

CLIMATE ACTION PLAN

EMWD’s 2022 Climate Action Plan provides detailed information on EMWD’s efforts to reduce Greenhouse Gas Emissions and reach statewide sustainability targets.

Climate Action Plan

Sewer System Management Plan (SSMP) 2016

The State Water Resources Control Board (SWRCB)adopted the Statewide General Waste Discharge Requirement for Sanitary Sewer Systems (WDR SSS) on May 2, 2006 that required the development and implementation of a Sewer System Management Plan (SSMP). The purpose of the SSMP is to document EMWD’s program to properly operate and maintain its sanitary sewer system. The SSMP also identifies the chain of communication for reporting overflows, from receipt of a complaint or other information, including the person responsible for reporting sanitary sewer overflows to the SWRCB, Riverside County Health Departments and the California Emergency Management Agency (CalEMA).

For further information or questions about EMWD SSMP, please contact Alfred Javier at 951.928.3777, ext. 6327.

Urban Water Management Plan (UWMP)

EMWD has prepared the 2010 Urban Water Management Plan (UWMP). The Plan updates the 2005 UWMP and has been prepared in response to Water Code Sections 10610 through 10656 of the Urban Water Management Planning Act. Included in the plan is detailed information about EMWD’s water demand, supply and reliability for the next 25 years.

HAZARD MITIGATION PLAN 

The EMWD Hazard Mitigation Plan is a living document that reflects ongoing hazard mitigation activities.  Hazard mitigation involves strategies to reduce short and long-term vulnerability to identified hazards.  This document serves as the framework for the ongoing identification and implementation of hazard mitigation strategies developed for the EMWD Service Area.  

EMWD adopted its previous Hazard Mitigation Plan in 2017.  This document serves as an update to that Plan.

REPORTS AND STUDIES

State Water Resources Control Board Report on Wholesale Water Supply

On May 18, 2016, the State Water Resources Control Board (SWRCB) replaced the February 2016 extension of the emergency regulation with a new water conservation standard based on a “stress test” approach that assumes three additional dry years. The new water conservation standard is to be calculated based on each agency’s available supplies. As part of this emergency regulation, agencies providing wholesale water supplies (such as EMWD) are required to publicly post the volume of water that they expect to deliver to retail water suppliers in the next three years. EMWD has made these estimates assuming that the potable demands from retail water suppliers would be equal to the average of the potable demands recorded in 2013 and 2014. Based on coordination with the retail suppliers on the amount of available local water resources available in the three additional dry years, EMWD has estimated the wholesale demands for each agency. These demands are to be met with imported water sold by the Metropolitan Water District of Southern California, of which EMWD is a member agency.

State Water Resources Control Board Report on Retail Water Supply

On May 18, 2016, the State Water Resources Control Board (SWRCB) adopted an emergency water conservation regulation that utilizes a “stress test” approach to determine a local water agency’s conservation standard. Agencies must self-certify their water supply for the next three years based on a repeat of the dry period from 2013 – 2015. The “stress test” methodology proposed by the SWRCB shows no shortages for EMWD over the three year analysis period, resulting in a mandatory conservation standard of 0%.

Hemet/San Jacinto GroundWater Management Area Annual Report

The Annual Report is prepared by EMWD for the Hemet-San Jacinto Watermaster. The Hemet-San Jacinto Watermaster has provided EMWD permission to publish the Annual Report on our website. This report documents the activities undertaken in support of the Hemet/San Jacinto Water Management Plan.

West San Jacinto Groundwater Management Area Annual Report

As a part of the West San Jacinto Groundwater Basin Management Plan, EMWD produces an Annual Report on the status of the groundwater sub-basins within the district.

Draft Quail Valley Sewer Improvements Alternatives Study

In 2005, EMWD hired PBS&J to prepare a study to identify and evaluate the collection system within Quail Valley. The objective of the study is to find a feasible solution to the problem of septic system pollution in that area.
