Automatic Water Softener Removal Rebate

For Our Water’s Sake, Use Alternative Water Softeners!

Protecting our local water supply is critical. Residential self-regenerating water softeners – the kind that uses rock salt or potassium chloride pellets – pose a serious water quality problem for our communities.

On average, a single self-regenerating water softener contributes up to 30 pounds of salt each month into our community’s water treatment system. That salt ultimately ends up in our groundwater and recycled water supplies. Salt is the single most important constraint on our future ability to use groundwater and recycled water, our most reliable and drought-proof local water supply.

That is why the Inland Empire Utilities Agency, with support from residents, businesses, environmentalists, local cities and other water and wastewater agencies, approved a regional ordinance prohibiting the new installation or replacement of self-regenerating water softeners.

What does the regional ordinance mean?

  • If you have a self-regenerating water softener now, you can keep it – you just can’t replace it. However we encourage you to remove it by taking advantage of IEUA’s rebate (up to $2,000) and free professional water softener removal service.
  • If you want to use a new salt-based water softener that does not harm the water supply, contact a professional service that collects and disposes of the salt canisters (exchange tanks).

Application Process

IEUA has launched a self-regenerating water softener rebate program. If you have a connected and working self-regenerating water softener, and live in the cities of Chino, Chino Hills, Fontana, Montclair, Ontario, Rancho Cucamonga, or Upland, you can get a rebate for the reasonable value of the unit—from $300 up to $2,000.

Applying for the rebate is simple:
Submit the one-page rebate application to IEUA with an original invoice or proof of purchase showing that the unit is fully paid and has no lien. IEUA will send you an offer with the rebate amount and your authorization letter to proceed. Sign the authorization letter and schedule an appointment with a plumber on the attached list. After the plumber removes your self-regenerating water softener IEUA will mail your rebate check.
