Frequently asked in Chicago

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 holds wastewater, allowing solids to settle out and form sludge, while lighter materials like grease rise to the surface as scum. The liquid effluent then moves to a drain field for further purification.

What is the average cost of a septic tank?

The cost to install a new septic tank in the Chicago area can fluctuate based on several elements. These include the tank's size, material, and the specific site requirements for installation. To get an accurate understanding of the price for your property, it's best to obtain a personalized quote from a local septic professional.

How long do septic tanks usually last?

When maintained correctly, a septic tank can last for a considerable time, often 20 to 30 years or even longer. The drain field, which is a critical component, typically lasts between 15 and 25 years. Consistent pumping and avoiding the disposal of inappropriate items are key to system longevity.

How often do septic tanks need to be emptied?

Most septic tanks require pumping every 3 to 5 years. This recommendation is based on average household usage and tank size. However, a professional inspection can help tailor this schedule to your specific situation in Chicago. It’s important to follow their guidance.

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

How often should a septic tank be pumped?
