What does a Water Department do?

A water department provides water to local residences and businesses operating within their service area. Typically this includes the delivery of safe drinking water as well as the removal of waste water through the associated sewer services. Additionally, any infrastructure repairs and improvements are the responsibility of the utility. These projects include water and sewer lines as well as any treatment plants required for safe operations. Water departments are also responsible for regular water testing. Testing ensures that the water provided to customers is safe to use and free of harmful contaminants.

Commonly asked questions about Water Departments

Will the Water Department repair my lines if they become damaged?

Whether the water department will fix the line depends on where the damage is located. Water and sewer lines that are on public property, such as under public roadways and sidewalks, are the responsibility of the water department. However, any lines located on your personal property may be your responsibility.

Do I have to use water from my local Water Department?

You are never required to use a service from any utility. However, there might not be a suitable alternative available. The most common alternative to water through a local service is through a well on personal property; however, not every property has water on it to support a well. Additionally, a permit is required to dig a well and, if you live in downtown areas a well might not be allowed. In these cases, your only option besides the water department may be to purchase water from a traditional retailer such as a grocery store.

How are Water Departments' price rates set?

Utility commissions often set water rates. These organizations determine a reasonable cost based on budgets required to provide the service to customers and maintain necessary infrastructure, including water and sewer lines, treatment plants and testing facilities.
