The Carroll Water Project, under the auspices of the Carroll Water and Sewer District, included the design and construction of a complete water system for the residents and businesses located within the Carroll Water and Sewer District boundaries. This system consists of some 85+ miles of 8" and 12" waterline, a water treatment plant with a design capacity of 1,000,000 gallons per day, a buried intake structure in Lake Erie, a raw water pump station, and a 500,000 gallon elevated water storage tank.

Brunkhorst Engineering Consultants, Inc. was asked by the Board of Trustees of Carroll Township in 1989 to perform a feasibility study to supply water to the residents and businesses of the Township. After due investigation, evaluation, and review of the various social and economic variables, the resultant study indicated that there was indeed a need for good water within the Township and that a range of financing options was available to construct a system to serve the area. In August of 1991, the Carroll Water and Sewer District was created under the provisions of Section 6119 of the Ohio Revised Code. Subsequent to this establishment of the District, Brunkhorst Engineering Consultants, Inc. was retained by the Carroll Water and Sewer District Board to provide the engineering/surveying services necessary to design and construct the water system outlined above. Brunkhorst Engineering Consultants, Inc. investigated various options and new innovative technologies for the proposed intake and the treatment process in an effort to minimize the capital costs of the system without sacrificing the quality and safety of the end product, potable water, to the District users.

After careful and thorough evaluation, Brunkhorst Engineering Consultants, Inc. recommended U.S. Filter's Tri-Zone equipment for the water treatment plant. This system incorporates two innovative technologies, pretreatment of the raw water with ozone and an adsorption clarifier to provide high quality water. The use of ozone increases the efficiency of particulate removal, helps control taste and odor problems, and reduces the amount of chlorine needed in the finished water. The raw water is brought in from Lake Erie through a large filter that was constructed in the lake bed. This sand and gravel filter significantly reduces the particulates in the raw water and ultimately results in higher finish water quality, lower chemical costs, fewer backwashes from the clarifiers and filters, and helps control problems due to zebra mussels.

The project was completed in the fall of 1998 at a cost of $20,000,000.
