NEW CONCORD — Zemba Brothers Inc., Zanesville, will serve as the contractor in the second phase of improvements at the New Concord Wastewater Treatment Plant.

In emergency action Monday, Village Council unanimously adopted a resolution awarding the contracts for equipment, electrical work and general construction to Zemba.

Zemba’s bid of $549,780.86 was the lowest total bid among the five contractors seeking the work.

Other (total) bids were $659,133.27 from Nicolozakes Trucking, $627,700 from Kirk Brothers and $678,093 from Mechanical.

Craun-Liebing offered a bid only for the pumps, $164,800. Zemba’s bid for the pumps was $159,990.

This phase of the construction will result in a new pump station that employs a new technology — ultraviolet disinfection, Administrator John Huey said.

Currently, the village uses chlorine to disinfect, Huey said. It’s a costly process for several reasons.

To begin with it’s an involved process because after the chlorine is used for disinfection, it must be removed before the cleaned water can be returned to the eco-system.

The chemical is extremely corrosive to the pumps.

“That chlorine just eats them up,” Huey said. “Under the current system we have had to rebuild the pumps and that’s about $7,000 annually.”

Add to that the cost of the chlorine — about $3,000 annually — and the yearly expenses accrue quickly.

New grinder units also will be installed to deal with affluent (influent) before it reaches the pumps and thus preclude some wear and tear on the pumps.

Huey said improved efficiencies, along with operational and maintenance savings, are expected to pay for about half of the debt.

Upfront, the village has received a $100,000 grant and a $500,000 low-interest (3.25 percent) loan to pay for the project.
