Big Dry Creek Wastewater Treatment Facility Solids Dewatering Project

The city’s Big Dry Creek Wastewater Treatment Facility (BDCWWTF), located at 132nd Avenue and Huron Street, treats an average of 7 million gallons of wastewater per day from the northern two-thirds of the city.  The biosolids by-product produced during the treatment process is stabilized, thickened and beneficially utilized as a soil supplement and fertilizer on permitted farms fields in the eastern part of Colorado.  The city will construct a new dewatering facility on the BDCWWTF campus to replace aging equipment and improve the efficiency of the overall solids management program, resulting in more efficient plant operations, reduced truck traffic and improved farm operations.

Project Details

The design of the new $23 million dewatering facility and other campus-wide improvements has been completed and the construction contract has been awarded to Archer Western Construction, LLC. Construction began August 13 and is anticipated to be completed by the summer of 2020.  Early construction activity will include setting up the field construction offices and preparing the site for the building foundation  An architectural rendering of the proposed dewatering facility is shown below.

Project Impact

Due to the proximity of this project to our customers, the city is taking special precautions to minimize disruption and inconvenience, including:

  • Hiring a specialty contractor with high qualifications specifically for this type of work. All contractors bidding this work will be required to meet specific qualifications.
  • Restricting work hours to Mondays through Fridays from 7 a.m. to 5 p.m. to limit the impact of construction equipment and work noise.
  • Weekend and evening work will only be permitted if special circumstances arise.
  • Careful monitoring of contractor compliance to state and local permit requirements for noise and dust control.
