"Great service. Only downside was a little extra cost for transport of recycled asphalt from Commerce city to northern Colorado. Virus shut down the local sources. Not Tanner's fault though and the the price was more than fair given the distance. Took 8 hours for three loads."

"Tatum Works showed up the next day, gave me a good price to fix my water leak (much better than the other two contractors I contacted) They finished the work faster than expected and restored my yard to the original state. We are so very happy with the entire project with Dustin and his crew. We would highly recommend this company."

Septic Tanks FAQs, answered by experts

Good news: You’ll naturally increase the bacteria in your septic tank simply by using it. If you want to encourage more good bacteria growth, stop using products and household cleaners that kill bacteria, such as bleach and harsh chemicals. Never flush antibiotics, and make sure only water and waste go down the tube—not paper products, feminine hygiene products, or diapers.

Frozen well pipes make themselves known quickly, as your faucets slow down to a trickle or shut down completely. If you notice a serious reduction in flow in the winter from toilets, showers, kitchen faucets, and other plumbing fixtures, a frozen pipe or two is to blame. Another tell-tale sign is frost or ice on exposed pipes outside. 

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

Deciding between an engineered septic system and a conventional one depends on property size, soil quality, local regulations, and environmental factors. If your property has limited space, poor soil, or is close to sensitive environmental features, an engineered system may be required. Professional site evaluations, considering water usage, long-term plans, and budget constraints, can help determine the appropriate choice. Consulting with a septic system professional is crucial for ensuring compliance with regulations and selecting the best system for your property's unique needs.

Start by finding the septic tank, marked by an access lid near your home. From there, the drain field extends outward in a series of trenches. Look for greener, lusher grass, as drain fields promote plant growth due to moisture and fertilizer. You can also check property records, use a soil probe to detect damp soil, or hire a septic professional with ground-penetrating radar equipment to map the drain field’s location.
