Distribution

5 systems

5 water systems, operated under local government ownership.

Delivery

4,540 people

Residents served across Timpson's service area.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by local government ownership and serves approximately 4,540 people through 5 water systems.
