About this service

Above-ground tanks are typically used in areas where the soil is unsuitable for traditional burial or where the water table is too high. These systems require a pump to move waste into the tank and then out to the disposal area. They require specialized maintenance to ensure the pump and piping remain insulated and functional. Costs are influenced by the pump system type. Exact pricing confirmed free on the call.

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.

Frequently asked in Portland

What is a septic distribution box and what does it do in Portland?

In Portland, the septic distribution box (d-box) is a crucial component that receives the effluent from the septic tank and evenly distributes it to the various lines in the drain field. This ensures that the wastewater is spread out for proper treatment by the soil. A failing d-box can lead to uneven distribution and system problems. We can help you find a pro to inspect it.

What does septic tank maintenance entail in Portland?

Septic tank maintenance in Portland typically includes regular pumping of the tank to remove accumulated solids and scum, usually every 3 to 5 years. It also involves periodic inspections of the tank, baffles, and drain field to identify any potential issues early. Educating household members on proper usage is also important.
