Constructing a new chlorination building to treat water for the citizens of Corry brings about a choice for the city — should gas or liquid chlorine be used — and gas was the final decision reached at a recent Corry Municipal Authority meeting, which is what the city already uses.
H and K Services, of Leon, New York, is finishing the interior of the building as part of an ongoing water project to upgrade aging infrastructure and a decision to use gas does several things.
A change order was issued for the switch, increasing the contract with H and K by $21,325, which is covered by contingency designated for such changes.
City Manager Jason Biondi said chlorination equipment was not included in the original contract, which means the city would have needed to submit a change order either way once a decision was made.
The choice of gas also keeps the water department using the same chlorination process it has been using.
"We are gas now and we would like to stay with gas," Corry Public Works Department Lead Operator Mark Leofsky said. "We designed the new building where we could do either one."
He said initially the liquid form was thought to be a good option but going through the water project brought about the change.
"Before we started the water project, we were entertaining the idea of going to a liquid chlorine system and as we worked throughout phase one and phase two of the water project … we feel staying with gas is a better option for the city of Corry at this time," Leofsky said.
Leofsky said the city could change to liquid in the future.
Leofsky said the new system will work with a SCADA (Supervisory Control and Data Acquisition) system — computerized controls.
The SCADA system works with analyzers and digital scales that read chlorine weight, Leofsky said.
Authority member Regis Dombrowski voiced concerns over the safety of a gas system.
Leofsky and Biondi both said they believe gas to be safer.
Biondi said in talking to the city's engineering firm and water system consultants, they also agreed the most consistent performing system would be gas if the city is comfortable with the safety protocols and procedures already in place.
"I feel comfortable this is a good decision for us long term," Biondi said.
