June 24, 2024  –There was an unexpected, significant water main break in the Terra Vallee area this morning. Water service from Mandan Middle School to Hwy 1806 N and 24th Street NW to Cascade Way NW is affected by this break. The contractor working on the fix anticipates being done by 6 p.m. Any additional updates will be posted to cityofmandan.com/news. City staff and leaders appreciate your patience and understanding as repairs are taking place.

Once water service is restored, if you notice discolored water or excess air in your water lines, please flush your cold water lines through a fixture that does not have an aeration screen, such as a bath tub spout or an outside water spigot, running until clear water is visible.
