Problem: Upper Blackstone Clean Water owns and operates an advanced wastewater treatment facility serving the communities within Worcester and six other surrounding towns throughout central Massachusetts with an average daily flow of 36 mgd. When the utility needed to replace their peristaltic hose pumps, they knew the importance of finding a pump that could pump thickened sludge for dewatering, but they were also focused on the cost efficiency when investing in a new pump.
Solution: After evaluating replace-in-kind options and reviewing other positive displacement pumps, the utility partnered with Penn Valley Pump to implement Double Disc Pumps within their facility. With few moving parts and minimal wear, the pump requires little maintenance, helping reduce overall life cycle costs. The maintain-in-place design allows the plant to rebuild the pump quickly without removal from the frame or disturbing the piping.
Result: After a successful 6-month trial as part of the company’s swap-your-pump program, the utility purchased a total of four units for their dewatering operation and two units for scum transfer so the facility could confidently continue the process of purifying water for its communities. 800-311-3311; www.pennvalleypump.com
