This article presents an AWWA task group report on evaporation control as a technological necessity in many areas of the country. The report presents a summary of several methods to control evaporation that include: site location; avoiding extensive areas having shallow water depths; avoiding non‐beneficial, water‐consuming phreatophyte plants; considering windbreaks; using floating covers, consisting of reflective materials such as white polyethylene spheres; considering seepage and water loss; and, using monomolecular films to reduce evaporation by damping the microwaves (ripples) and interposing an additional physical resistance. Lessons from field trials are discussed, along with computation of water savings, and evaluation of control compounds.
