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 Gresham
How does a septic tank actually work?
A septic tank in Gresham, Oregon, is the primary component of an on-site sewage system. Wastewater from your home flows into this underground container. Solids sink to the bottom as sludge, while oils and grease float to the top as scum. Bacteria naturally present in the tank begin to break down some of the waste. The liquid effluent then moves to a drain field for further filtration and treatment in the soil.
What does a septic pump service involve?
A septic pump service in Gresham, Oregon, means a professional team will come to your property to empty your septic tank. They use a specialized truck with a vacuum hose to remove the accumulated sludge and scum from the tank. After pumping, they may perform a visual inspection of the tank and its components. This service is crucial for preventing overflows and system damage, ensuring proper function.
What factors affect the cost of septic tank installation?
