On the Wabash River, a channel dam that has pooled future drinking water for the city is being replaced.
According to Miller, the dam, which has been in service for more than 100 years, is starting to show its age. Water has eroded the sides of the dam, leading it to potentially wash out if it is not replaced.
“Once a dam starts to erode on the back side, something needs done," said Miller. "At some point, the dam could have blown out."
The new dam is being built less than 50 feet away from the old dam, which will be demolished after the new dam is completed. The cost of the project is $1,031,875.
At the water treatment plant, an additional million-gallon clear well tank was built this year and a baffle was added to the current tank.
“The main reason for the baffle in the tank is that it creates a ribboning effect to increase the disinfectant contact time,” said Miller, adding previously the chemicals were not circulated, which created inconsistencies to the chemical levels.
A new lime softening system also was installed at the water treatment plant, softening the water delivered to city residents.
Another item the council approved for the water treatment plant was the purchase of the new actuators, which will allow improved control of the filtration process at the water treatment plant. The actuators, or electric motors, make automated shutoff of water line valves possible. The cost for the actuators is $51,758.60, plus $800 in shipping costs.
Work on the water treatment plant over the past two years has totaled more than $3 million.
Other infrastructures being improved include water mains and manholes.
During the meeting Wednesday, the council approved a change to the location of replacement water mains. The water mains were originally slated to be installed between Third and Second streets, but will now be installed near Edgar Street and Richland Avenue after it was determined the lines at Third and Second didn't need to be replaced. The 6-inch cast iron water mains, totaling 860 feet on Edgar and Richland, with replacement 8-inch PVC water main was also approved.
