Central Clear Creek Wastewater Treatment Facility (WWTF)

The WWTF is located near Dumont, Colorado, 40 miles west of Denver. The facility is permitted for an influent flow of 0.10 mgd and discharges into Segment 2c of Clear Creek just downstream from the confluence with Mill Creek. Segment 2c is "Use Protected" and classified as Recreation E; Aquatic Life Cold 1; Agriculture and Water Supply.

Description of WWTF

In 2019, Central Clear Creek Sanitation District finished a complete replacement of its existing sewage treatment system. Originally constructed in 1974, the existing system was no longer practical to maintain. Additionally, it was not capable of meeting future discharge permit limits. The new sysem installed by the District is sized to treat the same amount of sewage as the previous system, 120,000 per day. However, the demand on the system is typically only 25% of capacity. The new system features membrane bioreactor treatment technology which is the most robust form of treatment available. The technology combines the best of conventional treatment with filtration. The plant has consistently produced water cleaner than required by regulatory agencies since it has been in operation.

The District's new wastewater treatment plant features the Membrane Bioreactor treatment process.  The MBR is one of the most robust forms of wastewater treatment as it combines conventional activated sludge wastewater treatment and advanced filtration.  The wastewater is initially treated with a biological process to remove contaminants.  Once this process is complete a filter is used to remove remaining bacteria, pathogens, and nutrients to remain in compliance with the District's discharge permit.  The advantages of an MBR system includes better treated wastewater quality, smaller space requirements, and east of automation.
