Client: City of Moundsville Water Board, WV
Year Completed: 2008
Project Cost: $18,500,000
The $18.5 million project included the following unique elements:
- The plant uses advanced treatment technology for control of iron, manganese, disinfection byproducts, taste, odor, color, hardness, bacteria and pathogens
- Unit operations include ozonation (for pretreatment oxidation, pathogen deactivation); coagulation and flocculation (for chemical conditioning); multi-media/automatic backwash filtration system (for particle separation) and high-pressure nanofiltration (for hardness removal and submicron particle separation). All systems were pilot tested over several months to verify treatment assumptions
- The high pressure nanofiltration system also provides “log-removal credit” under the USEPA Long Term (2) Enhanced Surface Water Treatment Rule for inactivation of pathogens such as giardia and cryptosporidium
- The plant is supported by a micro-pile foundation system and a rock lined embankment above the 100-year, Ohio River flood plain
Project funding was provided by loans from USDA Rural Utilities Service and West Virginia Water Development Authority and grants from the USEPA STAG program and WVDEP. The project serves 4,500 customers in the City and Public Service Districts No. 3 & 4.
Extending over a 10-year period, GD&F performed pilot testing, planning, engineering, design, bidding, construction administration, construction inspection, funding applications and system start-up/commissioning services. The project will provide a dependable drinking water supply for the City and greater Marshall County area for many years.
