Document Description
IWVWD's proposed Arsenic Rule Compliance for Wells 9A, 10, 11, and 13 Project (the Project) consists of constructing and operating arsenic treatment facilities at existing Wells 9A and 13, the two IWVWD wells with the highest arsenic concentrations. Each treatment facility will consist of an oxidation, coagulation, and filtration treatment system for arsenic removal, and each will be designed to accommodate flows of approximately 1,200 to 1,500 gpm. Untreated water produced by Well 10 will be conveyed via a proposed 12-inch diameter pipeline to the treatment facility at the nearby Well 9A site for blending with treated Well 9A water, and the blended water will then enter IWVWD's distribution system via a short section of proposed 16-inch diameter pipe. Untreated water produced by Well 11 will be conveyed to the treatment facility at the Well 13 site via proposed 12" pipeline for blending with treated Well 13 water, and the blended flows from Well 11 and 13 will then enter IWVWD's distribution system near Well 13.
