MARYVILLE, Mo. — New water filtration membranes are slated to be the big-ticket item on next fiscal year's water and sewer budget, pending approval from the City Council.
In a water treatment facility, membranes are used to filter out unwanted substances in what will become drinking water. In a budget workshop Tuesday evening, City Manager Greg McDanel said the city's current membranes were installed in 2011 and are nearing the end of their 7-9 year operational life.
“As those membranes get older, the chemicals build up on those and you can only clean them up so much without damaging them, and so as they continue to build up, in times that are tough for water production, such as the winter, get harder and harder each year,” McDanel explained. “So I guarantee this is our last winter we have with our current membranes without having significant issues, and probably, we'll have to even increase production hours at the plant this winter to get through with our existing membranes.”
New membranes would cost around $1.8 million, including a full warranty and installation, the proposed budget estimated.
McDanel also recommended that the council discuss over the next couple of years coming up with a long-term plan for water treatment, which could include a new water treatment facility that would likely be handled in partnership with the public water supply district.
This year, no new rate increase for water and sewer service is currently included in the draft version of the proposed budget.
The new budget will be presented at a council meeting later this month ahead of the start of the new fiscal year on Oct. 1.
