Sewers collapsed, cars totaled: Omaha begins to total damage from Saturday's deluge

Flood totaled as many as 50 vehicles in just one Omaha parking lot

 

Omaha Public Works officials said Monday at least one section of storm sewer collapsed in Saturday's torrential rainfall, another two sections may have been damaged, and at least 50 vehicles parked in one downtown facility are likely totaled.

 

Omaha Public Works engineers Todd Pfitzer and Steve Andersen briefed the media on the repair and clean-up Monday. You can watch their briefing here:

 

"The Old Market garage had feet of water in it, it's now got inches of mud," said Pfitzer after a look at the parking facility at 10th and Jackson. Pfizer estimated as many as 50 vehicles parked in the lower level Saturday night would not be salvagable.

 

City crews used street sweepers and other heavy equipment to clean streets from the mud and dirt left behind by the rapid runoff.

 

Rain fell at a rate of 4" per hour between 8:00 p.m. and 11:00 p.m. Saturday as storms moved west to east across the metro Saturday night.

 

Inspectors were focusing on the hardest-hit area: Dodge to Martha, 50th Street to the River, inspecting sewer lines and streets as they looked for signs of buckling pavement and damage underneath street level.

 

"It's all hands on deck," said Andersen.

 

Andersen noted the Leavenworth Street corridor also was an area of significant damage.

 

"Those are areas where there's kind of a natural valley where that surface water runs down to the river so that was a lot of water on the street and carrying a lot of debris and so there's a lot of cleanup," said Andersen.

 

Pfizer also noted the damaged sewers are likely some of Omaha's oldest. Some of them date back more than a century. Ongoing and longterm efforts to replace the combined storm-sanitary sewer lines likely prevented some problems.

 

"We have taken storm flow off of that combined system and we have detention basins around town, and that has helped immensely over the last several years," said Andersen. "We're not seeing the impact as much as frequently as we used to with these type of events."

 

Andersen noted the main purpose of the CSO program is to hold the runoff temporarily so it can be processed through the city's water treatment facility.
