The Sewer Bypass Challenge: Sewer relocation in Boston required a bypass system for 900 million gallons of sewage over 75 days. Project challenges included placing the pump system in a very small footprint in a noise-sensitive residential neighborhood.
The Baker Bypass System: Baker service professionals worked with the general contractor to increase the pumping capacity from 23 to 43 MGD (million gallons per day) – providing a 20% safety margin. As luck would have it, back-to-back “100-year storms” inundated Boston part way through construction, followed by exceedingly dry periods. The dry-run pumps performed without a hitch and ran at lower RPMs for a $15,000 fuel savings, while sound-absorbing curtains around the project reduced noise by 30% at a distance of 30 feet.
