About this service

Septic treatments are additives designed to introduce beneficial bacteria or enzymes to your tank, helping to break down organic waste. While they don't replace the need for routine pumping, some homeowners use them to keep the biological balance healthy, especially if they use heavy amounts of household cleaners. You might consider these if your system is older or heavily used. Regular pumping remains the gold standard, but high-quality additives can sometimes provide an extra layer of support for your system's natural processes.

Summer often means more houseguests and increased water usage, which puts extra demand on your septic tank. With more showers and laundry loads, it is easier for a tank to reach capacity. If you have guests coming over, consider a pump-out beforehand to avoid an inconvenient backup during your family gatherings.

A septic distribution box is a crucial component of a septic system in Portland, especially for drain field function.

This even distribution is vital for preventing overloading in one area and ensuring consistent treatment of wastewater. Proper function prevents premature drain field failure, which is important given Portland's climate.
