Workshop Brief
The ability to store water is an important component of all public water supply systems. This can be accomplished with ground storage tanks or elevated tanks. But which one is the best choice for your system? How do you determine how much water should be stored? Is bigger always better? If I store too much water, is water quality an issue? This webinar will discuss the advantages and disadvantages of ground storage vs. elevated storage. It will provide guidance on how to determine the volume of water that should be stored for a particular system. It will discuss the consequences of variation of flow between summer and winter and how this variation can impact water quality, along with provide some guidance on what can be done, both from a design standpoint and an operational standpoint, to improve the quality of the water in a storage tank.
