Will a Water Softener Harm My Septic System?

While there have been concerns over a water softener’s impact on septic systems – such as killing the bacteria in the septic tank with salt, overflowing tanks with too much backwash flow and reducing the drainage field’s ability to absorb water – recent scientific remain inconclusive.
Salt has been found to have no harmful effects on bacteria and the soil of the drainage field. However, the volume of backwash flow can range from 55 to 100 litres per week or the equivalent of one to two standard filled bathtubs. Regenerating the softener not more than once a week should reduce the amount of backwash entering the septic system.
