New Water Treatment Updates Could Save GF MillionsThis new system would put in new shallower ponds and use a cycle system.
Approving proposed water treatment updates could mean long-term savings for the city of Grand Forks.
Not only that, but the updates would also make separating sludge from water much easier for the water treatment plant.
Right now the water the plant treats goes into 15-foot deep storage ponds, which have to constantly be cleaned out.
If the City Council approves this more than $3 million project, it could save the city $4.5 million over the course of 30 years.
In the past devices used to clean the water have involved a vacuum and later a pipeline.
Recently workers would have to physically clean out the ponds and haul the sludge away which has cost more than $290,000 annually per pond.
This new system would put in new shallower ponds and use a cycle system.
As one pond drains the water into another, the sludge remains in that pond and is able to dry out properly.
Over the years the cycle system will build layers of this dried material, which, according to director of public works Todd Feland, could be used to cover the landfill if city leaders choose.
Feland said if approved, the project could start in May 2012.
