To help take care of the drain field:

During heavy rain seasons, downspouts on your home can send gallons of stormwater to the septic system, which risks sewer water backing up into your home and overflowing into the Puget Sound. Disconnecting downspouts will greatly reduce the amount of stormwater that overwhelms the system. Read more to learn how to protect our waterways by managing rain on your property.

Other ways to take care of the drain field:

• Pick up after your pets. Keep your dog from digging in the drain field.
• Don't dig, drive stakes, or plant anything on the drain field. The roots of trees, shrubs, and invasive weeds can clog the drain field.
• Don’t flush harmful materials into the system. Limit garbage disposal use, as these disposals can contribute to solid matter build-up.
• Use water wisely and conserve water when you can.
• Report anything unusual. Odors, large pooled water, or exposed pipes may signify a problem.
