About this service

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.

How does a septic tank work in Portland?

A septic tank in Portland works by receiving wastewater from your home. Inside the tank, solids settle to the bottom as sludge, and lighter materials like grease float to the top as scum. Bacteria in the tank help break down some of these solids. The partially treated liquid then flows out to a drain field, where it is further filtered and dispersed into the soil. It's a self-contained system.
