Our Project Process

For private residential septic projects we ask owners to provide us with site parcel number/address, acreage, number of bedrooms for the finished construction, and, if available, a site map. We’ll discuss conditions on site with you. From this we create a free, all-inclusive, 30-day estimate based on what is generally required to install a regulation-compliant system in your area. Once the contract is finalized, we schedule a site visit for the soil evaluation Colorado requires. After the evaluation is performed, if the site qualifies for a gravity flow system under State and county regs, our certified techs design your system and update the estimate to reflect conditions on your site. This may be higher or lower than the initial estimate. Once this final estimate is approved, we submit the design to county, then install your system.

If you already have a septic design, you can provide a copy to us and we will create an estimate based it, then you jump into the process above at the point where we obtain county approval.

Commercial septic systems must, by Colorado regulation, be designed by an engineer. We can put you in touch with someone to design the system, or if you have a design, give you an installation estimate.

For residential excavation, roadway or sewer projects, we ask you to provide us with length, width, and depth or height of the proposed project, and discuss project details such as rock or tree removal, slope/grade, existing utilities, and proposed use for the site, so we can help make sure the end product meets your needs. From this conversation we create a free, 30-day estimate for the project. To contract with us, sign the estimate, return a down payment and we will be glad to schedule the work in a timely manner for you.

For commercial excavation, roadway or sewer projects you can send us plans or we can arrange a meeting to discuss your needs.
