About this service

Modern plastic septic tanks are made from durable, lightweight polyethylene. They are a popular choice because they are resistant to corrosion and easier to install than older concrete models. You might choose a plastic tank if you are replacing a failing system or building on a lot with difficult soil conditions. Because they are lighter, proper installation is critical to ensure they don't shift underground over time. We can help you determine if a plastic model is the right fit for your property.

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 Fargo

How does a septic tank work in Fargo?

In Fargo, a septic tank system functions as a decentralized wastewater treatment system. All wastewater from your home flows into the septic tank, where solids settle to the bottom as sludge and lighter materials like grease rise to the top as scum. Naturally occurring bacteria help break down some of this organic matter. The liquid effluent then flows out to a drain field, where it is naturally filtered and purified by the soil before it reaches groundwater. This process keeps wastewater from contaminating local water sources.
