Water & Wastewater
Energy reduction is a major concern in the collection system and at the WWTP. The two large, raw sewage pumps at the Glosser Road Pump Station operate with a variable speed drive system that matches the pump speed with the influent flow, which reduces energy demand. At the WWTP, one 15-horsepower waste-activated sludge pump was replaced with a one-horsepower-operated pinch valve to control the flow of waste solids from the clarifiers.
During the screen-replacement project, all raw-sewage flow was directed to one screen instead of two. This reduced electrical horsepower needs by six horsepower.
The blowers that aerate the sludge digesters have been put on a timer so that staffing has more operational and energy-reduction control on the solids-handling process. This has reduced the run time of five 15-horsepower motors by five hours per day each.
