"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. "

"I highly recommend Seamus, Kellen, and their team at Doone Brothers. They did my septic as well as my full site excavation/grading/driveway project. My site is very steep and challenging. I found them to be hardworking and fair. They went above and beyond with their communication and effort on my project and Iâ m super grateful to them for the work they did."

"Jason Dodge did a great job. Not only did he snake the drain in no time at all but he noticed the hot and cold water were reversed on my sink faucet and in 3 minutes he corrected it no charge! He couldn't have been nicer. I was only charged $100. for the whole thing. they have definitely become my go-to plumber!"

"Zach and Josh are professional and experienced. Arrived on time and were transparent about their work. Knowledgeable about underground piping. Confident about their work before backfilling. Work was done over thirty days ago and no leaks! I know because we have a water meter that uploads to a website that displays and identifies leaks. "

"Mario, the technician, seemed very nice and knowledgeable The $49 quoted trip charge turned into a $220 diagnostic charge not including any service. He wasn’t sure why water was appearing on the floor, but felt it may be due to some clogging of a PVC drain tube. He said it was not possible to simply clean it out, but it should be replaced at a cost of another $250 (for a pipe?). We declined. We subsequently had another repairman come in who said there is no problem cleaning the tube and did so. The material clogging the pipe is shown in the photo."

FAQs for septic system installation and replacement projects in Littleton, CO

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
