Right now, it's just a big ditch, but eventually it will hold a sewer pipeline that pumps effluent from Pembroke to the the Corfu sewer treatment plant. The $1.7 million project provides for upgrades to the plant, providing Pembroke, the school district and the area's business parks created by the Genesee County Economic Development Center with needed wastewater service. The project is partially funded by Department of Environmental Conservation grants, GCEDC grants and ratepayers. Construction started yesterday.
