About this service

Determining the total cost for a septic system involves looking at both the hardware and the labor required to put it in the ground. Factors like site accessibility, permit fees, and the size of the tank significantly impact the bottom line. Because every property is different, costs typically fluctuate based on what the soil requires for proper drainage. A site visit helps narrow down these variables. 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 Philadelphia

What is the purpose of a septic tank?

A septic tank is the primary component of an on-site sewage treatment system for homes not connected to a public sewer. It collects all wastewater from the house, separating solids that settle into sludge and lighter materials like grease that float. The liquid effluent then flows to a drain field for further treatment by the soil. This system is crucial for safe and effective waste management.

What is the average cost of a septic tank and installation?

How long do septic tanks usually last?

With consistent maintenance, such as regular pumping and professional inspections, a septic tank can last for 20 to 30 years, and often much longer. Neglecting these maintenance tasks can lead to premature system failures and expensive repairs. Prioritizing its care is essential for its longevity.

How often do septic tanks need to be emptied?

Most septic tanks should be pumped every 3 to 5 years. The exact frequency depends on the tank's size and the number of people using the system. If your household has more occupants or frequently uses a garbage disposal, more frequent pumping might be necessary to prevent solid buildup and potential clogs.
