About this service

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's main job is to collect wastewater from your home and separate solids from liquids. The solids settle to the bottom as sludge, and the liquids, called effluent, flow out to a drain field. This process is crucial for treating wastewater on properties without access to a central sewer system, especially common in areas surrounding Denver.

What is the average cost of a septic tank?

The cost to install a new septic tank in the Denver area can vary widely based on the tank size, type, and site conditions. Factors like excavation depth and the complexity of the drain field installation will also impact the overall price. For an accurate understanding of costs specific to your Denver property, it's best to get a personalized quote.

How long do septic tanks usually last?

With proper maintenance, a typical septic tank system can last for many years, often 20 to 30 years or even longer. Regular pumping and inspections are vital to extending the life of your system. This proactive approach is especially important in the Denver region to prevent premature failures.

How often do septic tanks need to be emptied?

Most septic tanks need to be pumped every 3 to 5 years, depending on household size and water usage. If your Denver home has a smaller tank or a larger family, you might need more frequent pumping. Ignoring this can lead to system clogs and costly repairs.

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

How often should a septic tank be pumped?

Pumping frequency for your septic tank in Denver depends on usage. A general guideline is every 3-5 years for a typical household. However, larger families or those with high water usage might require annual pumping to prevent solids from building up and causing issues.
