Glastonbury, CT Wastewater Facility Earns ACEC Award

State-of-the-Art technology improves effluent quality, reduces nitrogen discharge, and provides reliable, safe, and energy efficient operation

Recent design upgrades to the Glastonbury water pollution control facilities (WPCF) have earned an engineering Merit Award from The American Council of Engineering Companies (ACEC) of Connecticut.

The Glastonbury WPCF is one of the first Four-Stage Bardenpho processes in Connecticut to meet the 2014 nitrogen limits. To minimize operational costs and reduce safety concerns associated with chemical storage and handling, the WPCF was designed to avoid the need for supplemental carbon to achieve nitrogen reduction goals. Typically, many facilities use methanol (highly flammable) or other supplemental carbon source to allow the process to operate effectively.  By maximizing the size of the secondary anoxic zone, Wright-Pierce was able to provide a process that would meet low levels of effluent nitrogen without supplemental carbon.

A well-planned sequencing approach, a result of close collaboration between Wright-Pierce and the Town, allowed the Town to maintain necessary levels of treatment throughout the construction period.

In addition, energy saving features earned the project more than $125,000 from CL&P in funding. The facility improvements enable Glastonbury to provide the treatment capacity necessary to meet the Town's planned residential and commercial growth.
