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.

What is the purpose of a septic tank?

A septic tank serves as the primary treatment unit for wastewater in homes not connected to a municipal sewer system. Its purpose is to receive all household wastewater, separating solids from liquids. The solids settle to the bottom as sludge, while lighter materials like grease float to the top. The clarified liquid then flows to a drain field for further treatment in the soil before returning to the groundwater. It's a critical part of your home's infrastructure.
