Many utilities are considering or have implemented seasonal storage facilities (typically open reservoirs) to balance peak seasonal demands for reclaimed water (for example, irrigation) against the relatively constant supply from wastewater treatment plants (WWTPs). Storage changes the characteristics of reclaimed water and often algae will become a problem.

The objective of this project was to document  the water quality and cost trade-offs associated with storage options for the reclaimed water, considering the trade-offs involved in the treatment, management, and operating procedures at wastewater treatment facilities preceding discharge of the reclaimed water to the storage systems. This Resource Guide was prepared to assist utilities and consulting engineers by providing a decision-making framework (decision matrix) for meeting these objectives. It focuses on considerations of short-term or long-term storage and methods of treatment of the reclaimed water before storage.
