Should a Water Softener Discharge to a Septic System?

In most cases it should not be discharged into your septic system.

How a Water Softener Works

A water softener removes minerals like calcium and magnesium from hard water using a process called ion exchange. During regeneration, the system flushes out these minerals with a brine solution (saltwater), which is then discharged as wastewater.

Potential Effects on a Septic System

1. Increased Water Volume

Softener regeneration adds extra water to the septic tank. If the system is small or already near capacity, this additional flow can reduce retention time and push solids into the drain field.

2. Salt (Sodium) Concentration

The brine discharge contains sodium, which can:

  • Alter the soil’s structure in the drain field, reducing its ability to absorb water.
  • Affect the bacterial activity in the tank that breaks down waste.
  • Corrode concrete or metal components over time.

3. Bacterial Impact

Some studies suggest that moderate salt levels don’t significantly harm septic bacteria, while others show reduced efficiency in waste breakdown. The effect often depends on the system’s size, soil type, and water usage.

A water softener should never discharge to a septic system. Instead diverting the discharge to a separate location is safer. A separate dry well or dedicated discharge line can be installed to handle the brine safely. Always consult a licensed septic professional, licensed plumber or local authority before making changes, however it is the homeowners responsibility to know where the water softener discharges to.
