Exceeding customer expectations in pipeline pigging project for local Water & Sewer District
SFE Global was contracted by a local Water & Sewer District to clean a wastewater force main due to poor performance. We exceeded the customer’s expectations with pipeline pigging by decreasing friction loss, increasing pump flow and efficiency and reducing energy costs of pumping.
The image reflects a flow trend showing the difference, before and after pigging.
Before: ~ 55 gpm each pump.
After: ~180 gpm with two pumps, ~ 164 gpm with one pump
