Water Supply Wells, Treatment Plant and Storage Facilities – Seelyville, Indiana

HWC provided planning, permitting, design and construction administration services for the construction of a new Water Treatment Facility and new Distribution and Storage System for the Seelyville Waterworks Utility in eastern Vigo County, Indiana.

Phase I of the project included the development of a new water supply well field, a new water treatment facility, new water transmission mains and storage improvements.

Phase II of the new system provided necessary flow and pressure to approximately 250 homes on the western extremity of the Seelyville system via a new isolated pressure zone served by a new 500,000 gallon tank and booster station.

Phase III included analysis and design of the improvements for the treatment facility to serve approximately 400 new customers in an unserved township northeast of the utility. The preliminary study and design for this project included modifications for additional capacity for the filters and chemical feed systems.
