Schlaff presents council with waste-water treatment plant equipment needs

The Dexter City Council was advised on the state of its waste treatment plant during its regular meeting at the Dexter Senior Center, Monday evening.

“Last week we had a blower go out at our water filtration plant,” Dan Schlaff said.

He is the director of public works for the city of Dexter. There are three “blowers” in the plant. They are used as part of the “airation process.” 

Two years ago, Shlaff said that they had to use two blowers to get enough oxygen into the process to make it work. Originally they only needed one at a time.

“I didn’t see this coming, so it’s a little bit of an emergency,” Schlaff said.

The blowers were installed in 1999. They have since gone out of production and there are no replacement parts available. And because the remaining blowers have to remain on, Schlaff said he has no way of knowing if the other two blowers need to be replaced or not.

Schlaff said that this did at least present the city with an opportunity to modernize. Installing a new, equivalent model would cost the city between $40,000 and $50,000, plus $10,000 for installation.

A more modern, energy efficient blower, Schlaff said, would be able to use the water it filtrates much more efficiently. That would be greener and would cost the city less because it would not have to run all the time.

“There’s a lot of different options out there [with] energy savings,” Schlaff said.

He said that the new models would have a meter on them which would measure demand. “As demand goes down, the energy goes down.”  

Schlaff also brought up possible increases in future demand and safety. He said that the current blowers could blow up if they were “dead headed” or had “defusuer problems.” The new blowers have fail safes to prevent this.

The city council did not vote on whether or not to replace the filtration blower.
