In this paper the authors examine opportunities for energy savings at water treatment facilities in North America and how energy savings can be achieved. The authors discuss specific approaches, such as using variable speed drives and high efficiency motors as primary sources to realize increased payback of original equipment cost. In addition, this paper explores life cycle costing as a method to justify investment in equipment upgrades, moving beyond just simple payback periods. The authors use existing treatment facilities for reference throughout the paper. Includes 4 references, tables, figures.
