RECYCLED WATER FACILITIES
PLANNING STUDY
(STUDY)
2/9/2017
Item 12.b
1
Background
In 2014, the Council directed staff to pursue the following goals:
Meet the City’s future projected water demand of its buildout population by:
Meeting the reduction in per capita use as prescribed in the Water Conservation Act of 2009;
Proceeding with work necessary to develop a recycled water project that can be used to prevent seawater intrusion in order to provide long-range protection of the City’s groundwater
supply; and
Ensure water use efficiency and drought protection through regional conjunctive use, storage and management of surface and groundwater supplies.

Background – Recycled Water Progress
NCMA Technical Group’s Strategic Plan (2014)
Regional Recycled Water Strategic Plan (2014)
Integrated Regional Water Management Program funded a basin characterization of the Santa Maria Groundwater Basin (2015)
City of Pismo Beach Recycled Water Facilities Planning Study (2015)
SSLOCSD/City of Arroyo Grande Satellite Water Resource Recovery Facility (2015), which became the Recycled Water Facility Planning Study in 2016
Regional Groundwater Sustainability Project Letter of Intent (2017)

Discussion
Today we are happy to report a major milestone with the Study.
The past eight months, District and City of Arroyo Grande staff has been busy working with WSC to complete the Study.
A full copy of the Study is posted on the District’s website.

Review RW Program Goals & Objectives
Identify ways the District can contribute to developing a resilient water supply portfolio for southern San Luis Obispo County;
Investigate and document potential regulatory, scientific, financing, jurisdictional, and public acceptance constraints to the District developing a recycled water system;
Identify opportunities for the District, its member agencies, and regional stakeholders to overcome these constraints and outline a strategy for developing an additional, resilient,
drought-proof source of water supply;
Provide an opportunity to educate the public and project stakeholders about recycled opportunities in the region; and
Coordinate with other local efforts to develop a regional recycled water program.
