PALMYRA, Mo. — The Palmyra City Council agreed to move forward with a $750,000 upgrade to the municipal wastewater treatment plant, following the recent failure of one of the facilities two rotors used for treatment.

Mark Bross, water/wastewater department manager with Klingner and Associates, presented three possible options for repair and upgrades at the facility. The first two options he presented would replace the failed rotor with one of two different designs. 

He said the first two options were less costly, but they would not meet forthcoming Missouri Department of Natural Resources regulations regarding treatment for nitrogen and phosphorus. 

He presented a third option which would use pipes instead of rotors to treat wastewater by forcing oxygen into the water. He said the equipment and installation costs would be greater, but the annual operation costs would be about $8,000 less for electrical use.

Council members approved the third option. Bross noted he worked with Brent Abell, Board of Public Works superintendent, to apply for State Revolving Fund money for the project. He added that the efficiency of the new system would reimburse the city's investment within two to three years and provide the capacity to treat between 50,000 and 75,000 gallons of additional wastewater.
