Water system planning, as required by WAC 246-290-040, provides the framework for making key water supply management decisions. An integral part of the comprehensive Water Shortage Response Plan is the City’s course of action in the event of possible water shortages.
A water shortage can be described as any situation in which the water supply is insufficient to meet the demand. A shortage may occur for a number of reasons, but it is most commonly a result of drought conditions. Other factors that can cause a water shortage include contamination, inadequate planning, shallow wells, inadequate pumping, water waste and losses due to emergency conditions such as an earthquake.
The Plan discusses shortages associated primarily with drought conditions, and how to effectively maintain the water supply so that the basic needs of the citizens of Tumwater are met in the event of a water shortage.
