DES MOINES &#8212 Ottumwa residents resumed regular household water usage Saturday, but a boil order remains in effect for the city through at least Sunday.

The city’s sewer system had backed up into its water treatment plant and officials had been hoarding a limited water supply. Bret Voorhees, a bureau chief with Iowa Homeland Security and Emergency Management Agency, said Saturday that the city’s water pumps are working and that work crews are recharging the system.

Plant officials are still running tests to run to determine the water’s purity. Voorhees said that city officials hope to have the plant back to normal by Monday.

The boil order, issued Friday, is a safety precaution. Officials are still asking that residents boil their tap water for two minutes before consuming it.

Meanwhile, Lt. Governor Patty Judge toured Mystic on Saturday. Sixteen families in the town had to be evacuated due to flooding.

Judge said that, starting on Monday, the state plans to put assessment teams – aided by the Federal Emergency Management Agency – into the field to determine the extent of the damage caused by the flooding.

“They have suffered a real loss, so the next step for us is to try to figure out what kind of assistance is available and what we can do to try and help them,” Judge said.

Judge said there is still a substantial amount of debris and damage throughout the town.

Gov. Chet Culver visited Wapello and Van Buren County Friday. Both have praised local efforts to assist those affected by flood damage.

“What the governor has seen, and what I’ve seen this week across this state is a tremendous outpouring of volunteers,” Judge said. “Everyone has really pulled together.”
