- The JKMuir team worked with an energy services company to perform a preliminary energy audit of the GLWA WRRF. The WRRF and its pumping systems treat an average of 650 MGD, with a peak capacity of 1,700 MGD. JKMuir worked with the project team to identify pumping system optimization opportunities and energy savings measures at the WWRF. The goal of this project was to identify cost-effective energy savings opportunities at the WRRF, quantify potential cost savings for each measure and estimate project costs.
- JKMuir’s involvement included evaluating the pumping systems and mechanical equipment. The pumping systems evaluated included units ranging from 100 HP to 2500 HP, and the opportunities identified included pump rehabilitation, pump replacement, motor replacement, variable speed pumping, pumping hydraulic modifications, and pump sequencing optimization. The development of these opportunities included field work and meetings with operations personnel as well as stakeholder meetings to engage the facility staff. To assess the impact of proposed energy reduction and maintenance/operational benefits, JKMuir quantified energy savings associated with various equipment and operational upgrades. The resulting recommendations provided the opportunity for savings up to 19,000,000 kWh a year, and $1.2M in annual cost reduction.
