Some key capital programs are set up to increase infrastructure reliability.

  • Colorado River Aqueduct Reliability - Projects under this program will replace or refurbish facilities on the Colorado River Aqueduct system in order to reliably convey water to Southern California.

 

  • Treatment Plant Reliability - Projects under this program will replace or refurbish components at Metropolitan's five water treatment plants in order to reliably meet treated water demands and comply with all applicable water quality regulations.

 

  • Distribution System Reliability - Projects under this program will replace or refurbish existing facilities within Metropolitan's distribution system, including reservoirs, pressure control structures, hydroelectric power plants, and pipelines in order to reliably meet water demands.

 

  • Prestressed Concrete Cylinder Pipe Rehabilitation - Projects under this program will refurbish or replace Prestressed Concrete Cylinder Pipe lines to maintain water deliveries without unplanned shutdowns.

   

  • System Reliability – Projects under this program will improve or modify facilities throughout Metropolitan's service area in order to utilize new processes and/or technologies, and to improve facility safety and overall reliability. These include projects related to Metropolitan's Supervisory Control and Data Acquisition (SCADA) system and other Information Technology projects.  

 

Conservation programs:

  •  bewaterwise.com is the website providing information on rebates, water saving incentives programs, grants , surveys etc.
  • The watering index is a scientifically based number (uses ET data) used to help save considerable amount of water by guiding the amount of water used by sprinkler system with weather change.
