The water tower at the edge of the village of Genoa is in need of repairs that could cost up to $30,000.
“They found some rust spots, nothing major, but they need to be taken care of to prevent further rusting,” said Genoa Village Administrator Kevin Gladden.
Nelson Tank Engineering of Lansing, Mich. recently used robotic inspectors to check the integrity of the storage tank situated along Ohio 163. The rust spots are located along some of the rings where the steel is welded together. Gladden reported the finding to Genoa Village Council during the mid-April meeting.
“It’s going to need cathodic protection. We’ll have to empty it, attach anodes and it’ll stop the rust,” Gladden explained during a telephone interview Monday.
Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. The simplest method to apply CP is by connecting the metal to be protected with another more easily corroded sacrificial metal to act as the anode of the electrochemical cell. These systems are commonly used to protect a range of metallic structures including steel water or fuel pipelines and storage tanks, ships and boats as well as offshore oil platforms.
Gladden has contacted Poggemeyer Design Group of Bowling Green, the village’s engineering consultant, to create specifications for the repair contract as well as a cost estimate.
“It’ll probably cost between $20,000 and $30,000. It won’t be cheap. They basically have to go up inside the thing and apply the anodes,” Gladden said. The village also will likely take advantage of the repair down time to have the tank cleaned well with a chlorine rinse, he added.
The job will require the village to drain the 500,000-gallon tank before crews being work.
It should not interfere with residents’ daily use of water though, he said. There is a second water storage tower located in the park.
The maintenance is well overdue, Gladden said.
The last time he recalled such work being done was 1999, Gladden said. A robotic check took place about three years ago, however, the previous administration did not act on the maintenance, he said.
The repair job will likely take place in spring 2013.
“We don’t have the money budgeted this year for that kind of work. It’ll probably have to wait until next spring,” Gladden said.
