The August issue of Journal – American Water Works Association features a new case study of a public works project that aligns water and energy efficiency.
“Logan, Utah: A Case Study in Water and Energy Efficiency” describes Logan City’s challenge to manage both resources and the innovative solution Hansen, Allen & Luce (HAL) provided. The paper is available here.
HAL employees Steven C. Jones and Robert B. Sowby contributed the article with coauthor Paul W. Lindhardt, Logan’s water division manager.
The project involved well and pump station retrofits and the implementation of a new pressure zone. One year later, Logan’s water system had reduced energy costs by 32%, water use by 17%, and mainline breaks by 40%. The project eliminated the need for an expensive transmission project and postponed the development of a new water source.
Lindhardt is pleased with the results. “[The project] has helped make Logan City’s water system more efficient to the point of saving over $100,000 per year in just energy savings,” he said. “It has been amazing to see how familiar [HAL] has become with how our system operates. That familiarity has led to many suggestions and operational recommendations for improvements above and beyond the typical scope of work.”
The project was named APWA Utah’s Public Works Project of the Year for its innovative concept and positive results.
HAL has provided professional services in civil engineering, water resources, and the environment for over 40 years and is a recognized leader in water system optimization and energy management.
