Why was the Conservation rate originally put in place?

The Washington State Department of Heath requires us to file an approved water system plan that includes a water use efficiency program. Their focus is on maximizing existing resources to allow for future growth and population expansion. The absence of water use efficiency and planning could result in an inability for our natural resources and the services that provide them to sustain the population. Since the Washington State Department of Health is not authorized to control growth and population expansion, their solution to conserve water became a mandate to water utilities and their customers.

While other utilities use a multi-tiered conservation rate that affects all of its users, our water system plan uses a rate method that affects only the people who actually use quantities that exceed average use. Since 15% of our customers use 80% of the water during summer months, they become responsible for the excess use, instead of charging people who utilize conservation methods and stay below the range of excess use.
