What affects the price

The final bill for septic work depends on a few specific variables. First, the size of your tank and the total volume of waste removal play a role. We also look at the accessibility of your tank lids; if they are buried deep underground or hidden under landscaping, extra labor is required to reach them. The distance from our truck to the tank also impacts the setup time. Every property has unique plumbing needs, and exact pricing is confirmed free on the call.

Frequently asked in Denver

What factors influence the cost to install a septic tank in Denver?
How does a septic tank work to treat wastewater?

A septic tank is a buried, watertight container that serves as the primary treatment unit for wastewater from your home. All wastewater flows into the tank, where solids settle to the bottom as sludge, and lighter materials like grease float to the top as scum. Bacteria naturally present in the wastewater help to break down some of the organic matter. The partially treated liquid, called effluent, then flows out to a drain field for further purification. This process effectively removes most contaminants before the water re-enters the environment.

What is the best toilet paper for a septic system?

For optimal septic system performance, it's best to use toilet paper that is labeled as 'septic-safe' or 'septic-friendly.' These products are designed to break down quickly and easily in the septic tank, minimizing the risk of clogs and buildup. Avoid using thicker, multi-ply papers or those with added lotions or fragrances, as these can be more difficult for the bacteria in the tank to process. Choosing the right toilet paper is a simple step towards maintaining your system. Ask for advice when you call.

What are the signs of a failing septic tank drain field?

Signs of a failing septic tank drain field in the Denver area include persistent wet spots or standing water in your yard, sewage odors, or slow-draining plumbing fixtures. You might also notice unusually lush or green patches of grass over the drain field area. If multiple plumbing fixtures are backing up, it's a serious indicator. Addressing these issues promptly with professional help is crucial to prevent further damage and potential environmental contamination. Call for a free assessment.
