Approximately 30% of the wastewater in Colorado is treated through onsite wastewater treatment system technology. COWC is a leader in the design of new onsite wastewater treatment systems and replacement, repair or upgrade to existing systems. All projects begin with an initial in person evaluation to assess site and soil conditions, topography, and potential impacts from surrounding properties. From there we work with our client to establish what the system will be utilized for so that we can calculate the anticipated wastewater flows accurately and design the best wastewater treatment system possible for your project while keeping cost and curb appeal in mind.
We have completed over 1,500 designs across the Front Range ranging from new construction of onsite wastewater treatment systems, to repairs of existing systems. We have experience with engineering systems on extreme slopes with bedrock, to properties with high groundwater and restrictive soil conditions.
Our portfolio contains a wide variety of designs for large flow systems ranging from RV parks, schools, churches, summer camps, retail, gas stations, restaurants, long term care facilities and more. We have experience working directly with the Colorado Department of Public Health and Environment permitting process for large flow systems.
Many projects are required to submit grading and drainage plans to mitigate the impact of development on water quality, or to create egress for emergency vehicles at your site. COWC has experience creating drainage and storm water management plans as well as driveway and site grading and excavation engineering.
We offer services from simple driveway engineer to whole project grading and erosion plans. Our grading and drainage plans encompass best management practices and requirements from the local and state level.
