SAWPA - One Water One Watershed

One Water One Watershed (OWOW) is an innovative Integrated Regional Water Management Plan (IRWMP) planning process being developed within the Santa Ana River Watershed.

Through collaborative strategic partnerships and building upon the successful watershed planning in the past, the next generation of integrated regional watershed planning is under development to solve problems on a regional scale, and give all water interests a voice in the planning process.

The “One Water One Watershed” (OWOW) 2.0 Plan is the Santa Ana River Watershed’s integrated regional water management (IRWM) plan. This plan reflects a collaborative planning process that addresses all aspects of water resources in the watershed over a 20-year time horizon. OWOW 2.0 reflects a new suite of innovative approaches that lead with a water demand reduction strategy, instead of relying solely on continued imported water deliveries. These approaches include multi-beneficial projects and programs that are linked together for improved synergy, proactive innovative, and sustainable solutions, integrated regional solutions supporting local reliability and local prioritization, watershed based project and programs that effectively leverage limited resources, promote trust and produce a greater bang for the buck, and integrates water supply, water quality, recycled water, stormwater management, water use efficiency, land use, energy, climate change, habitat, and disadvantaged communities and tribes.

During the last two years, water resource managers from every sector have been working together, through workgroups referred to as “Pillars,” to write OWOW 2.0. The strategies of OWOW 2.0, which are cemented in the Plan’s Broad Planning/Management Guidance Strategies were distilled from that work and will serve to guide future planning and management in the watershed. If we integrate OWOW 2.0’s strategies into our daily lines of business and consider the Pillar’s Recommended Implementation Actions listed in the OWOW 2.0 Executive Summary, we will have taken major steps toward combating the Six Horsemen of the Apocalypse.

OWOW Plan (IRWMP)

OWOW 2.0 Plan

SAWPA officially launched this Integrated Regional Water Management (IRWM) planning effort on April 20, 2011, with the signing of a partnership agreement with the U.S. Bureau of Reclamation. OWOW 2.0 is not merely an update of OWOW 1.0. Under its theme of “Moving into Implementation” the Plan lists recommended watershed level actions for implementation. Click here to view the OWOW 2.0 Plan.

OWOW 1.0 Plan

SAWPA officially launched the IRWMP planning effort during a meeting on April 17, 2007, in which 178 officials representing more than 100 agencies in Riverside, San Bernardino and Orange counties met to discuss the framework for the OWOW Plan, a shared vision of the Watershed.  From the very beginning, the process has been opened to, and has received the participation of representatives from all geographic regions and political jurisdictions within the watershed, and from diverse representatives of different sectors of the community (governments, water agencies, development and environmental community, and the public at large).Click here to view the OWOW 1.0 Plan

Past Integrated Regional Water Management and Watershed Plans

Santa Ana Integrated Watershed Plan, 2005 Update

The 2005 IWP Update was prepared by SAWPA and adopted by the SAWPA Commission in June 2005. This document provides updates to projects that are important to successfully continuing the Integrated Watershed Program in the Santa Ana River Watershed.

Water Resources Plan 2002 Volume Number 1

Part 1 and Part 2, Volume Number 2

In 2002, SAWPA developed a multi-phased planning process called the Integrated Watershed Plan (IWP). This Plan has three components: the SARI Planning Study, the Integrated Water Resources Plan, and the Environmental & Wetlands Component. This Plan is closely related to the Southern California Integrated Watershed Program (SCIWP).

Environmental & Wetlands 2002

The Water Resources Plan was first written in 1998 to provide a watershed-wide evaluation of water supply needs and plans for projects that would support meeting these needs. This activity is designed to update the 1998 Water Resources Plan to optimize the use of all water resources in the Santa Ana River watershed, integrate the watershed planning effort with Metropolitan Water District’s Integrated Resources Plan Update, and provide descriptions of future projects within the Santa Ana River watershed. The current SAWPA Water Resources Plan was initiated in fiscal year (FY) 1994-1995 and was completed in FY 1997-1998. The benefit of this project was the development of a single document that combines the demands and available resources for all the member agencies to help resolve anticipated future shortages in the watershed. It is necessary that the information be updated to assure current regional planning alternatives using the latest data possible.

The document was designed to:

  • Gather existing and projected water demand and supply data from member districts.
  • Determine potential local and regional projects to optimize available water resources.
  • Integrate watershed planning with Metropolitan Water District Integrated Resources Plan Update.
  • Provide descriptions of future local and regional projects, and participate in and support the Santa Ana River Dischargers Association.
  • Compile information into a single document.

The Plan was based on the 2000-2001 population, water demand, and water supply information as the project baseline, and then planning horizons were developed for 2025 and 2050.

SARI Planning Study 2002

SAWPA owns capacity rights or owns outright approximately 93 miles of pipeline known as the Santa Ana Regional Interceptor (SARI) Line. Construction on this pipeline began in the 1970′s and has had several additions up through the year 2001. This planning study reviews the use of the line, maintenance, costs, and provides recommendations for future actions.

How do I get involved?

Engaging stakeholder involvement in a large, diverse watershed is challenging. It is unlikely that any one individual “knows” all of the stakeholders, and as such, the development of mailing lists and notification of workgroup meetings can be daunting. The OWOW process was designed to be different from other planning processes. One critical difference is that OWOW was designed to be a “bottom-up”, rather than a “top-down” process. By encouraging participation from different groups of people and those holding varying viewpoints from throughout the Watershed, the capacity to reach larger numbers of stakeholders also grew.
