Environmental issues being solved by city

Wednesday, April 27, 2011

A day before Lewisburg called for bids on a $13 million dollar sewage treatment plant expansion, the utility's superintendent said he's working to prevent sewage backups in three basements.

Rain on a drainage area between Jackson and Glenn avenues raises the water table, increases groundwater flowing into broken sewer pipes, and increases the likelihood of wastewater rising from three basement drains.

It's a localized example of hydrology that's to be resolved at the treatment plant with construction of a holding tank. That and increasing the plant's treatment capacity are to be built within a year and a half.

Pipe repair in a subdivision near the county garage could be done by Memorial Day, depending on the weather, and certainly before July 4.

Such explanations come from Kenneth Carr, superintendent of the Lewisburg Water and Wastewater Department. The city Water and Wastewater Board met Thursday afternoon.

That's when Carr reported five sewage backups, although there were only three homes involved because two homes had backups twice.

About 1,300 feet of eight-inch pipe is to be installed to resolve the problem at Jackson and Glenn avenues, Carr said. The city's cost is estimated at $15,000 to $20,000.

Meanwhile, broken service lines and sewers are to be replaced in a city housing authority development, he said. Pipes can be replaced up to the house because the city owns those public housing units.

The utility board has unanimously approved the projects.

Approval for the $13 million sewage treatment plant is in compliance with an order from the Tennessee Department of Environment and Conservation.

Bids are to be opened at 2 p.m. May 10 at the utility's offices on Water Street. A pre-bid conference was scheduled for 10 a.m. on Tuesday.

Once the successful bidder is awarded a contract, that company will have 540 calendar days to finish.

Because federal stimulus money is being spent on the plant expansion project, the prevailing wage rate in the area must be paid to project workers under the federal Davis-Bacon Act of 1931.
