About this service

When planning for a septic project, remember that you are paying for both the equipment and the labor. The tank itself is just one part; you also have to pay for the excavation, piping, and drain field installation. The total amount is typically influenced by the depth of the water table and the materials used for the tank. Getting a professional site assessment is necessary to understand your specific needs. 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 Oklahoma City

What is the purpose of a septic tank?

A septic tank acts as a primary treatment unit for wastewater from your home. It separates solids from liquids, allowing solids to settle and decompose. The clarified liquid then moves to a drain field for further purification. This system is vital for properties not connected to city sewer lines, ensuring safe and effective waste management.

What is the average cost of a septic tank?

How long do septic tanks usually last?

A well-maintained septic tank can last for 20 to 30 years, sometimes even longer. Regular pumping and inspections are crucial for longevity. Neglecting maintenance can lead to premature system failure, resulting in expensive repairs or replacement. Proper care ensures your system functions efficiently for years to come.

How often do septic tanks need to be emptied?

Septic tanks typically require pumping every 3 to 5 years. This frequency can increase if your household uses a lot of water or has more occupants. Overfilling can cause solids to enter the drain field, leading to system damage. A professional can help determine the best schedule for your Oklahoma City home.

How much does it cost to have a septic tank pumped?

How often should a septic tank be pumped?
