Project Details:
Black River Overlook, 28 affordable housing units in Ludlow, VT constructed by Okemo Realty in 1996, had been plagued with water quality issues, excessive concentrations of iron, manganese, hardness, calcium since opening.
The 1996 water treatment system was limited and vintage and desperately needed upgrade and replacement.
The project scope included complete reconstruction of the water room, replacement of pumps, controls.
The Drinking Water and Groundwater Protection Division required manganese concentrations be reduced to below a secondary contamination standard of 0.05 mg/l pursuant to the requirements of Subchapter 21-6 of the Vermont Water Supply Rule, Chapter 21. The 0.05 mg/l secondary maximum contaminant established for Manganese at in the Vermont Water Supply Rule is much lower than the Vermont Department of Health Advisory standard of 0.3 mg/l. A new water treatment system consisting of aeration, three carbon filters, two water softeners, and two chlorination systems (pre & post) was designed, permitted, and constructed.
Blair Enman, PE, Principal and Founding Partner, and Patrick Griffin, PE, project Manager, Enman Kesselring, note: We expect many Small Scale Public Community Water Systems will likely fall to the new 0.05 mg/l jurisdictional threshold for Manganese.
Enman Kesselring Consulting Engineers, PC, was retained by Housing Vermont (address) to address the water quality issues. In conjunction with Waite Heindel, Hydrogeologists, Burlington, and Vermont Water Treatment Company, Enman Kesselring along with Housing Vermont, lead the team of consultants.
The General Contractor was Naylor & Breen, Kim Levins, Brandon, Scott Hayden, Hayden Plumbing, Brandon, and Vermont Water Treatment Company, John Beauchamp, Rochester. Housing Vermont’s representatives were Rich Wickman, Project Manager, and Kathy Beyer, Vice President for Development
