Solid waste facilities are divided into sections called cells, where waste is stored during the decomposition process.
When a solid waste facility maxes out capacity in an existing cell, it typically builds a new cell expanding the footprint.
Before any waste material can be stored in the new cell, the area must be prepared.
Nine acres of sub-grade is prepared for the placement of a four-layer system of liner and geocomposite.
The redundant layers provide added protection for the environment.
The subgrade is sloped, allowing any incoming rainwater to flow toward a sump area to pump away the leachate water for treatment.
Rainwater that falls onto the waste is collected and treated for the protection of groundwater and environmental waterways.
A system of perforated drainage piping is installed on top of the liner system to handle the volume of water.
The pipes are then covered with large river rock then sand to filter the water entering the pipes.
A Force Main and series of pumps then pump the leachate water to the treatment center.
Upgrades to the pumps and piping systems of the existing cells are also a part of COMANCO’s scope of work.
