Frequently asked in Dallas

What is the purpose of a septic tank?

A septic tank serves as the primary treatment unit for wastewater in homes not connected to a municipal sewer system. It collects all household sewage and allows solids to settle out as sludge, while lighter materials like grease float to the top. The clarified liquid then moves to a drain field for further purification.

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

How long do septic tanks usually last?

With regular maintenance, a septic tank system in Dallas can typically last between 20 to 30 years. This includes periodic pumping and avoiding the disposal of harsh chemicals or non-biodegradable items. The drain field, which is also a critical component, may have a lifespan of 15 to 30 years.

How often do septic tanks need to be emptied?

For most homes in Dallas, pumping the septic tank every 3 to 5 years is a standard recommendation. However, the exact frequency depends on the tank's size and the number of people using the system. A professional can assess your tank's contents to determine the optimal pumping schedule.
