ENGINEERING SERVICES

Onsite Wastewater Treatment Systems (Septic Systems)

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.
