Switch To Hybrid Blowers Offsets 68% Electrical Rate Increase For WWTP

The Old Orchard Beach Wastewater Treatment Plant (WWTP) serves the town of Old Orchard Beach, Maine, a coastal resort community where the population swells from 9,000 year-round residents to 75,000 in late June through early August, when seasonal residents and day trippers descend for the peak summer months.

Ahead of a scheduled rate increase from its electricity provider, the WWTP hoped to offset rising energy costs by replacing its 15-year-old positive displacement (PD) blowers with efficient new equipment that would cut back on both energy consumption and maintenance requirements
