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.
