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 Chicago

What is the purpose of a septic tank?

A septic tank's primary function is to treat wastewater from homes not connected to a public sewer system. It receives all household sewage, allowing solids to settle and form sludge, while grease and lighter materials float to the top. The partially treated liquid then flows into a drain field for further purification by the soil. This process is vital for environmental protection and public health.

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

How long do septic tanks usually last?

With consistent maintenance, including regular pumping and inspections, septic tanks can last for 20 to 30 years or even longer. The lifespan can be significantly shortened by neglect, leading to potential system failures and costly repairs. Proper care is an investment in the longevity and reliability of your entire septic system.

How often do septic tanks need to be emptied?

Most septic tanks require pumping every 3 to 5 years. This frequency is influenced by the tank's capacity and the number of people using the system. Households with higher water usage or those that frequently use a garbage disposal may need more regular pumping to prevent system overload and backups.

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

How often should a septic tank be pumped?

A good rule of thumb is to have your septic tank pumped every 3 to 5 years. This interval might need adjustment depending on household size and usage habits. For a family in the Chicago region, understanding your specific needs is key. A professional can help you establish the most effective pumping schedule for your system.
