About this service
Your septic tank acts as an underground settling chamber. Wastewater flows from your home into the tank, where solids sink to the bottom as sludge, and grease floats to the top. The remaining liquid flows out into the drain field for natural soil filtration. If you notice standing water or odors in your yard, the system may not be separating waste properly. System complexity affects service costs. 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.
