Urban Water Use Efficiency

LA Urban Area

Urban water use sectors include residential, commercial, industrial, institutional, and other water use sectors.

Water that is not used for agriculture or to support the environment is referred to as “urban water.” Urban water includes water that is used for:


  • Drinking
  • Toilets and showers
  • Landscaping
  • Car washing
  • Businesses
  • Industrial processes


Climate change, population growth, land development, and increasing regulations on water use impact our water supply, which means that we must be more diligent in conserving the water we have now, so that we have sufficient supply for the future.  


Water waste costs everyone. Waste leads to higher water prices, and developing new water supply solutions such as building more reservoirs, water recycling, and desalination, are all expensive options.  


To help ensure that we use our urban water supplies wisely, the Urban Water Use Efficiency program provides information and assistance to water suppliers, agencies, and the public in several areas:


  • Urban water management planning and other water supplier management and reporting requirements
  • Leak detection information and resources to reduce water waste
  • Understanding and implementing the Model Water Efficient Landscape Ordinance (MWELO)
  • Commercial, Institutional, and industrial water efficient practices
  • Tips on what individuals can to do save water

This section below is to provide clarity for urban water suppliers on their reporting requirements to the California Department of Water Resources (DWR) and the State Water Resources Control Board (State Water Board).
