If you live in an area with hard water and also have a septic system, you may have heard conflicting information on whether to using a water softener is harmful to your septic. There are good points on both sides of the argument; however, most of the negative points against using a water softener with a septic system are based on older models of water softeners. The short answer is yes, water softeners can affect your septic system. That being said, there are ways to minimize the effects so that you can enjoy the benefits of softened water and maintain a healthy septic system.
Water Softeners Effects On Septic Systems
The biggest concern with water softeners on septic systems is the large amount of water discharged when the softener regenerates. This can be up to 150 gallons of water, depending on the type and size of the water softener. This surge in water use can cause a backlash on the septic system, pushing partially treated water out into the drainfield before it is ready. This can add to the growth of biomat and eventually lead to septic backups or drain field failures.
However, there are some solutions to this issue. First, most newer models of water softeners only regenerate based on water used, unlike older models which regenerated based on a timed system. This can reduce the number of regenerations and negative effects on the septic. Another solution is to drain the discharged water from the regeneration process outside of the septic if it is allowed under your local municipality or county codes.
If you have a water softener or are considering adding one, talk to your local septic professional on what is the best way to protect your septic system. They can offer advice on what is the safest way to add a water softener without jeopardizing your investment in your septic system.
