The tap water in Ames, Iowa, is safe to drink again.

City officials announced Sunday that the order that water be boiled first had been lifted.

Ames was forced to shut down its water system Wednesday after broken water mains were discovered as a creek and river flooded large swaths of the city. By Thursday, residents were allowed to use small amounts of water for showering or flushing toilets. Crews have repaired or isolated the broken mains.

John Dunn, the city's water and pollution control director, says there are no remaining restrictions on water.

The flooding in Ames came after three nights of heavy rain caused creeks and rivers in central Iowa to swell earlier in the week.
