OTTAWA — Putnam County Commissioners heard a proposal Thursday to install a wetland at the county landfill to treat the leachate on site that will reduce the expense of hauling it.
Greg Bockrath, project engineer for Bockrath and Associates, and Troy Recker, project designer, attended the meeting to discuss the proposed project.
Leachate is defined as liquid that has drained through a material and has picked up some of that material.
“It is costing the county approximately $20,000 a year to treat the leachate. We have space where we can construct a wetland treatment system,” Bockrath said.
The firm agreed to get back with the commissioners within the next week on a price for engineering for the treatment wetland project.
Recker said soil tests have proved an additional lining will not need to be used. The native soil can be used and that will help with project costs, according to Recker.
“The clay is thick enough to hold and support the wetland,” Recker said.
The commissioners will still need to approve the project and a design phase will take place as well as permitting with the Environmental Protection Agency that will be a six- to nine-month process, according to Bockrath.
“What we are looking at is instead of trucking the leachate off site, putting it into a treatment facility on site at the landfill facility, treating it on site and discharging it to the receiving stream,” Bockrath said.
Vincent Schroeder, commissioner, said currently the county hauls the leachate by tanker to the Ottawa Wastewater Treatment Plant and the county is charged by the Village Of Ottawa to treat the wastewater.
“We started working on the project a year ago. We are spending $20,000 to treat the wastewater and the price is going up so we want to put in a wetland to eliminate that expense,” Schroeder said.
Michael Lammers, commissioner, also said the project will help with reducing expenses.
“We are looking for a proposal. If we are spending $20,000 a year to dispose of this water if we could use this wetlands concept it makes a lot of sense,” Lammers said.
Another project is a waterline project at the Putnam County Fairgrounds that is out to bid. There will be several waterlines replaced there that are used to fill tankers in the infield, restrooms and water line connections for vendors.
