3 Tips for Doing Laundry With a Septic System


A septic system has different needs than a sewer connection. Connecting your septic system to your washing machine is possible, but if done incorrectly, you can potentially damage or overwhelm the system. To make septic system maintenance easier and extend the life of your system, follow these tips.

Laundry Tips for Septic System Maintenance

1. Choose a Mild Laundry Detergent

Harsh chemicals are hard on septic systems. The system relies on beneficial bacteria inside the tank to break down solid waste so the liquid can escape through the drain field. Large doses of cleaning chemicals can kill off the bacteria. As a result, solid waste will then build up more quickly and you’ll need more frequent septic tank pumping. Choosing a septic-safe laundry detergent while also avoiding bleach and other harsh chemicals will help preserve a healthy population of bacteria and minimize your need for septic tank maintenance.

2. Reduce Water Use

Large amounts of water flowing through your septic system can overwhelm the tank and saturate the drain field. Whenever possible, reduce the amount of water you use for your laundry. You can do this by only washing full loads or adjusting the load size on the machine’s settings to match the amount of clothing you’re washing. When it’s time to replace your washer, choose an energy-efficient model designed to use less water.

3. Spread Out Your Loads of Laundry

Even if you aren’t wasting water, doing many loads of laundry at once can overwhelm your system. Instead of having one “laundry day” when you wash all your clothes, spread the loads out throughout the week. This allows time in between loads for the water to enter the drain field and for the soil to gradually dry out.
