In 2004, Brodhead Creek Regional Authority (BCRA) initiated the development of a new well source (Well No. 3) along McMichael Creek to increase their available source water supply. Upon startup of the well in 2010, BCRA experienced production and water quality challenges. Subsequent water quality sampling identified turbidity spikes and indicated the presence of coliform bacteria that led to the determination that Well No. 3 is a Groundwater under the Direct Influence (GUDI) of surface water. After repairs to the well casing to address shallow groundwater and surface water intrusion had failed to completely mitigate the risk of surface water intrusion, BCRA determined that filtration of Well No. 3 would be required and selected membrane filtration as the most viable treatment option.
RETTEW developed an equipment procurement solicitation document to receive detailed proposals from relevant membrane manufacturers for the proposed filtration system. We evaluated the manufacturer responses based on capital and operating costs for the proposed membrane filtration system and pilot testing. Based on RETTEW’s evaluation, BCRA selected two membrane manufacturers to conduct pilot testing. RETTEW prepared a pilot testing protocol and actively partnered with BCRA during the pilot testing and design phase of the full-scale Well No. 3 water filtration facility project.
