The City of Milbank will drain the water tower today. While this sounds extreme, City Administrator Jason Kettwig explained it is normal and the process is done every three to four years to enable maintenance.
“We perform this type of maintenance regularly to clean the inside coating and prevent rusting,” said Kettwig. “As long as no major repairs are needed, the job should be completed by the end of the day.”
According to Kettwig residents should not notice any difference. “There might be a slight change in the color of the water, but it will be minimal and disappear quickly,” he said.
The process is simple. Pumping of water to the tower ceases for the day which allows water to drain from the tower. “With our new system and pump house, this is an easy job,” Kettwig said. The pump house is able to maintain 50 pounds of pressure – the normal weight. Three pressure reliefs around the city trigger and release additional pressure as necessary.
Maintenance will also be completed on the above ground storage tank. The tank is washed, cleaned, and examined.
