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.
Frequently asked in Denver
What is the purpose of a septic tank?
A septic tank is a crucial part of an on-site sewage treatment system. Its main job is to collect wastewater from your home, allowing solids to settle out as sludge. Liquids then flow into a drain field, where they are further treated by soil and microorganisms. This process prevents raw sewage from contaminating your property or local water sources.
What is the average cost of a septic tank?
The cost of a septic tank itself can vary widely based on size and material, but this often doesn't include installation. Factors like the type of tank, whether it's concrete, plastic, or fiberglass, and its capacity will influence the price. It's best to get a specific quote for your property in Denver, as excavation and installation add significant costs.
How long do septic tanks usually last?
With proper maintenance, a septic tank can last for several decades, often 20 to 30 years or even longer. Regular pumping, avoiding harsh chemicals, and being mindful of what goes down your drains are key. The drain field, which is part of the system, can also last a long time if the tank is well-maintained. Preventing backups is essential for longevity.
How often do septic tanks need to be emptied?
Septic tanks typically need to be pumped every 3 to 5 years, but this can depend on household size and water usage. If you have a large family or frequent guests in your Denver home, you might need more frequent pumping. Ignoring this can lead to costly backups and damage to your entire system. It's wise to schedule regular check-ups.
How much does it cost to have a septic tank pumped?
The cost to pump a septic tank can depend on the size of the tank and your location within the Denver metro area. Factors like accessibility and any additional services needed, such as minor inspections, can also affect the price. To get an accurate figure for your specific situation, it's recommended to call for a direct quote.
How often should a septic tank be pumped?
As a general rule, septic tanks should be pumped every 3 to 5 years. However, this frequency can change based on the number of people living in the house and their water usage habits. For homes in the Denver area, it's wise to consult with a local professional for a personalized recommendation to avoid issues.
