Construction & Development
Building something? Did you know that all new construction, changes of use and most renovations for residential and commercial projects must be evaluated and approved by the Water & Sewer Department (WASD)?
WASD's role is to evaluate the project's proposed use to ensure the availability, integrity and capacity of our infrastructure, which is designed to protect public health.
Construction & Development Payments
Payments for construction and development charges can be made online with a credit/debit card only.

Construction Project Requests
Learn about requests for projects within or along state roads; the re-platting or permanent closure of roads with existing water and sewer infrastructure; and excavations.
Cross-Connection Control & Backflow Prevention
A cross-connection is an actual or potential link between the potable water supply (water safe for human consumption) and a non-potable source (any other type of liquid, gas or substance not fit for consumption and that can affect water quality).
A cross-connection can be avoided by eliminating the link between the two sources. If the link cannot be removed, then the potable water supply must be protected through the use of a backflow prevention assembly.
