What affects the price

About this service

The price for a new septic installation depends on several key factors. The primary drivers are the number of bedrooms in your home, which determines the tank size, and the results of your soil percolation test. If the ground requires a specialized treatment system, the total will be on the higher end of the spectrum. Costs typically sit in a broad range depending on these site 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.

With regular pumping and proper care, a septic tank can last for 20-30 years or even longer. The drain field's lifespan can also be extended with good maintenance. Avoiding flushing inappropriate items is key to longevity.

Septic tanks generally require pumping every 3 to 5 years. This frequency can be influenced by the number of people in your household and your water usage. A professional can advise on the best schedule for your Memphis home.
