Water Use Efficiency & Conservation

West Basin Municipal Water District (West Basin) develops, implements and provides cost-effective water efficiency programs to local communities in its service area to help save water and increase local water supply reliability.

In addition to augmenting local water supplies, West Basin’s water efficiency and conservation programs also help residents and businesses become more water efficient and reduce their water and energy costs.  Water efficiency has multiple benefits that include lowered energy costs, reduced urban water runoff, and pollution prevention.

West Basin’s water efficiency programs include a variety of programs and resources that assist every customer sector. In partnership with the Metropolitan Water District (MWD), West Basin provides educational classes, water surveys, free water efficiency devices, and rebates.

West Basin collaborates with the South Bay Environmental Services Center, local cities, water retailers, Los Angeles County, non-profits and other stakeholders to promote programs and assist the public with participating in the District’s various programs.

Water Use Efficiency Data Study


As a continuation of its leadership and proactive planning approach for water use efficiency, West Basin completed its third Water Use Efficiency (WUE) Data Study in 2019.  The objective of the WUE Data Study is to provide a plan that articulates guiding principles and strategies for West Basin’s WUE programs and services, and facilitates innovation and adaptability given California’s rapidly changing water resources landscape.

The WUE Data Study was developed in close coordination with West Basin staff, local cities, water retailers and environmental groups.  The 2019 Plan focused on the following major areas:

  • Coordination with Stakeholders
  • Proactive Response to Regulatory and Other Drivers for Water Conservation
  • Innovative Analysis of WUE Programs
  • Strategic Recommendations

The WUE Data Study analyzed current programs, changing demographics, new drivers for water efficiency and surveyed the local water retail companies to evaluate their needs to comply with new WUE regulations.

The 2019 WUE Data Study provides West Basin staff with valuable data to develop strategic and targeted programs in coordination with the local cities, water retailers, and other stakeholders.

West Basin is well prepared to develop new programs and strategies that will help meet the state’s future water use efficiency requirements. See archived plans below.
