High river levels and the recurring lowland flooding along the Missouri River at Plattsmouth have the City of Plattsmouth taking extra steps to fix a troublesome predicament.
The Cassgram reports that city officials have known about a break in a 24-inch sanitary sewer main for several weeks. The flooding has been persistent since early June and has not allowed crews to get to it to make repairs.
The broken main is allowing dirt to get in the system. “The longer that pipe remains broken, the more risk we incur at the Waste Water Treatment Plant,“ wrote City Administrator Erv Portis in a memorandum to city council members.
At the August 2nd meeting, the council approved the immediate hiring of Kerns Excavating of Plattsmouth to make emergency repairs. Because the flooding in the area north of East Main Street near River Road has not subsided enough since then to allow the repairs and the river forecasts call for continued high levels for months, the council has now authorized Kerns to also begin building a dike around the existing sinkhole.
The project includes removing the water and installing a system to temporarily bypass the broken main during the repair process. The contract with Kerns says costs are not to exceed $82,110.
After the main is fixed, another contractor, Utility Services, will come in “to vacuum the silt, sedimentation and other materials that have caused the plant’s bar screen to stop operating,” said Portis. That contract calls for costs not to exceed $38,000.
