Water Softeners

The Nine Springs Wastewater Treatment Plant is not able to remove salt from wastewater, so every bag of salt that goes into a water softener passes through the treatment plant and into local streams. Increasing your softener’s efficiency protects our freshwater resources.

Salt Savers Program

Optimizing softeners for household water use and local water hardness can reduce salt use by 25% to 50%. If your household softener uses more than 1 bag of salt per month, have a professional tune it up or replace it with a high-efficiency model.
