Two types of storage needs must be addressed when developing a wastewater reuse system. One type provides operational storage, and the other is used for storage during poor weather conditions.
A minimum amount of operational storage is needed to give the operator flexibility to adjust, maintain, and service the irrigation system. All wastewater reuse systems need to provide a small amount of operational storage, which should be calculated as follows:
Unless discharge to a receiving stream is possible, most systems will need to store wastewater through the winter months. One approach to determine anticipated storage needs is to set up a monthly chart covering one year. The chart will show the required storage needed in terms of design flow.

| First installed in 1973, the wastewater reuse system at Deer Creek State Park is the oldest operating system in Ohio. Wastewater from the lodge, campgrounds, and all other park facilities is treated and stored in one aerated and one storage lagoon. Solid-set irrigation sprinklers distribute the wastewater to an isolated 12-acre field adjacent to the lagoons. |
