Swimming Pool Filter Replacement Rebate

Here's a dirty little secret about your old swimming pool filtering system:

It wastes water, energy and money. It's time to consider a new water- and energy-efficient cartridge filter system. Here's why:

  • SAWS will give you a rebate up to $250 on your water bill when you replace your pool's sand or diatomaceous earth (D.E.) filter(s) with a new high-efficiency cartridge filter system.
  • Replacing your sand or D.E. filter with a high-efficiency cartridge filter system can reduce your water consumption by as much as 20,000 gallons per year.
  • Translation: Lower water and energy bills.


Pool filtering system All participants in the SAWS Pool Filter Replacement Rebate program must:

  • Be SAWS water customers for the requested installation property site.
  • Own their pools and have either a sand filter or diatomaceous earth filter.

Participants shall not hold SAWS Conservation responsible for pool water quality or any costs associated with maintenance or repairs.

Rebate Details:

  • Rebate will be credited to the SAWS water account of the applicant.
