Dale Clark and His Team Achieved $22,000 in Annual Energy Savings for Only a Tiny Investment

Saving energy in clean-water plants often starts with the efficient use of air. Dale Clark and his team at the lagoon-based clean-water facility in Clare, Michigan, have achieved about $22,000 in annual electricity savings on average — roughly 19% — by making changes to the aeration system that cost only a few hundred dollars.
