Rates & Service Areas

Customers of DMWW pay a rate per thousand gallons of water they consume each month. In addition, customers pay a flat monthly availability charge that is based on the size of meter approved for the property. If a customer uses no water in any given month, only the availability charge will apply. The availability charge covers fixed costs that are not dependent on the amount of water consumed, and include costs for customer service, metering and meter reading, and costs for the pipeline to serve your property, to name a few examples.

Rates include a component for replacement cost depreciation which funds the utility's capital program. The rate structure seeks equity among the user classes and service areas with regard to the cost of producing and distributing treated water.
