Centralized Wastewater Treatment Services in Colorado

The National Western Centralized Wastewater Treatment Facility, a division of MFEI, has processed non-hazardous waste streams properly for over 20 years. Additionally, we own and operate a state and federally permitted facility for the treatment of sub categorical; B (oily water) and C (organic) contaminated ground and surface water as well as non-categorical septic and grease trap waste. Full package services include testing, profiling, specialized transportation, treatment, storage, resource recovery for beneficial use, and disposal.

If you have liquids from construction sites, tainted surface water, groundwater siphoned off to avoid floods, oils, grease, or particular non-hazardous residues, they all need special treatment. That’s where our facility steps in. Situated near where I-25 and I-70 cross, we efficiently treat, filter, purify, and handle wastewater. Plus, our services span the entire Rocky Mountain region and nearby states.

Your Solution for Groundwater Treatment & Remediation

By providing a centralized wastewater treatment facility, National Western Centralized Wastewater Treatment Facility  offers local government and municipalities the opportunity to direct and refer the generators or transporters of various non-hazardous liquid waste materials to a safe, local low-cost processing and disposal facility. Oily wastes, restaurant grease, sand trap residues, and other similar non-hazardous waste by products require special handling and treatment prior to proper disposal. These materials must be properly processed in order to prevent the fouling of municipal waste treatment facilities, to avoid potential contamination to state water, and to comply with state-required regulations.

We are a state-approved facility focused on handling groundwater treatment involved in construction site dewatering, transportation, treatment, and disposal. Our facility is not only efficient but also affordable. Furthermore, we are capable of processing anything from a small volumes to large tanker truckloads exceeding 6,000 gallons. Once solid wastes are processed, they can be mixed with other industrial materials. This approach enables us to use these waste materials beneficially, as opposed to going through expensive permitting for on-site treatment or only being allowed to landfill them.
