Wade Phillips, Public Works Director for Harrison, told the Carroll-Boone water board last week that his city must implement corrosion control to protect its delivery system. The strategy Phillips suggested is to inject a corrosion inhibitor at the Bear Creek metering station, which is owned by CBWD.
Phillips said the plan is to install a tank to hold zinc orthophosphate, which would enter the Harrison water supply through a tie-in to the line. Phillips said the process would not interfere with CBWD operations, but Harrison equipment and supplies would be on CBWD property. He said at least 30 water systems in Arkansas use the same chemical for corrosion control, and the idea is to create a layer inside the pipes to control lead leaching into the water.
Engineers, then lawyers, will assess length of time, liability, and lease particulars, which will be presented to the board at a later date.
Connell told the board the metering station has only a pipe that comes up and runs through a meter and then on to Harrison. Chair Jim Yates said CBWD would need the engineers to look at the setup and determine the legal responsibilities associated with the plan. He said he had no issues with the concept.
Hammond agreed McGoodwin, Williams and Yates would work with Phillips on the plan and report back.
