Workers from Moltz Construction of Salida have been making progress on Cedaredge's new sewer treatment plant for almost six weeks since construction began.
Last week they were in the process of pouring concrete that will make containment walls of the 25-foot-high treatment cells of the plant.
The two cells will have a capacity of 375,000 gallons per day, twice that of the town's 30-year-old wastewater treatment lagoons that the new mechanical plant is replacing.
Two of the present lagoons will remain in service and dredged and retasked as "aerated sludge holding ponds," according to plan drawings reviewed by the DCI. The other two lagoon cells will also be dredged and the space on site used as an "emergency overflow pond."
According to the project engineer, final completion of the new sewer treatment plant is scheduled for December 2016.
