Work on the fourth of five planned “cells” at the Washington City Landfill is expected to be completed by the end of October, according to Andrea Lueken, assistant city engineer.
The landfill is located on the Struckhoff Farm off Bluff Road.
Crews with J.H. Berra Construction Co. mobilized for the project the week of Sept. 2 and began with erosion control and the clearing of trees and grub. Excavating the cell began earlier this week with the moving of soil and grading.
So far, work is on schedule and going well, Lueken said.
“Right now we’re on schedule or a little ahead of schedule,” she said. “We’re hoping for no rain delays or unforeseen conditions.”
The excavation phase of the project is scheduled to take place through the last week of September, in which the installation of leachate pipe and berm removal will begin.
During the first three weeks of October, the trench will be anchored and liner will be installed.
The final step, the placement of protection soil, is scheduled to be finished by the end of October.
City council approved a contract with SCS Aquaterra for engineering and supervision services related to the project. The estimated cost for services provided by the firm is $77,900.
A second contract was awarded to Berra Construction Co. Inc. for actual construction of the fourth cell.
Once the fourth cell is finished, a portion of the first cell will be excavated and trash will be relocated from it to the new cell.
The excavation is being done to bring the city into compliance with the Missouri Department of Natural Resources which cited the city several years ago for overfilling Phase I, said Jim Briggs, city administrator.
Because of the odor that will be involved with opening the first cell, moving the trash will likely be done during the winter months and in the evening.
The city began developing the landfill in 1997 under a 20-year lease of the farm property.
