Aggregated Small Property Program

Westside Water Resources oversees the funding and installation of groundwater recharge systems that redirect rooftop rainwater out of our sewer system and into our aquifer.

Qualifying properties may be eligible for:

  • NSF Certified roof coating

  • Up to 95% reduction of the stormwater charge on your water bill

  • Native Landscaping

  • System performance monitoring system
