Iron & Manganese Removal Plant — East Lyme, Connecticut
LEI was retained by the Town of East Lyme Water & Sewer Commission to design a 500 GPM capacity treatment facility for Production Well No. 4. This 24" x 36" gravel packed well replaced a 30' deep caisson well, which had historically high iron and manganese concentrations.
A 36' x 66' split face block treatment plant building was constructed in a residential area. This building encloses the vertical turbine well pump, three 8' diameter manganese greensand filtration vessels, and a 150KW stand-by generator.
