A Montana Homeowner's Guide to Septic Systems
This document was originally reviewed and published in accordance with U.S. Environmental Protection Agency policy. The original document was modified and reviewed for use in the state of Montana by the Montana Department of Environmental Quality, Solid Waste Section, Septic Tank Pumper Program.

“This homeowner’s guide will help you care for your septic system. It will help you understand how your system works and what steps you can take, to ensure your system will work properly. A checklist is also included at the end of the guide to help you keep track of your septic system maintenance.”

Note: It is generally not standard practice to put pumped waste back into a septic tank. While tanks are designed to operate 90-95% full of water (not solid sludge), putting back pumped material often implies a “dewatering” technique used to break up solid sludge or simply because of improper disposal practices.

The Goal is Removal: The purpose of pumping is to remove accumulated solids and scum to prevent them from entering the drain field, as noted in discussions on Facebook. Backwashing Practices: Some companies may backflush to break up sludge, but returning half of the waste is not standard practice and may indicate improper procedures.
