The replacement will cost about $1.365 million, and Public Works Director Pat Flood said the added efficiency of the upgrade would save the city thousands of dollars each year spent on power used to run the outdated filtering equipment or membranes, on overtime.
Flood explained during the Monday council meeting that the filters were installed in 2003 and are losing efficiency.
“The membrane actually does the treatment,” he said. “The average life of a membrane is about seven years; we’ve outlived the life of the membrane. We’ve reached a point now where they have to be replaced, we can’t keep up with the flows when it rains.”
The equipment at the Rubes Creek WRF are more than a decade old, and Flood said when heavy rain increases the water flow, extra staff have to work at the facility to keep up with the flow.
“For five days after it rains, they have to stay 24/7 until we get caught up on the flow,” Flood said.
Replacing the membranes would allow the city to spend less on personnel costs, Flood said, and an upgraded aeration system will help save significant energy.
Flood recommended replacing the membranes with similar technology to save money because upgrading to the newer technology would mean more engineering costs to make the facility compatible.
After about seven months of research into various technology options, Flood and other city officials reviewed three different proposals before deciding to recommend the General Electric option.
The council unanimously approved the $1.365 million purchase of GE wastewater treatment upgrades.
Flood said the new membranes are expected to arrive in mid-July and will be installed immediately after the city receives them.
