The Indiana-American Water Company consists of seventeen separate water supply systems serving 18 communities in the State of Indiana, with some of the largest being Kokomo, Muncie, Richmond, Terre Haute, Jeffersonville and Greenwood. The total state-wide customer base includes approximately 170,000 households. During 1993, the Indiana-American Water Company acquired the resources of the Indiana Cities Water Corporation. As a result of this acquisition, new water supplies began to be developed to insure that reliable water service would be available to the systems in Indiana. Due to rapid growth and increasing water demands in several former Indiana Cities systems, it was deemed necessary to utilize a fast-track, design/build method for the simultaneous construction of three water treatment plants in Johnson, Montgomery and Hamilton Counties as part of the Central Indiana Systems Improvement Project. This design/build facility delivery method proved essential in quickly and economically increasing the system capacities of those communities where the existing systems were at, or near, their rated design capacities. Due to the uniformity in much of central Indiana's groundwater supplies, the three groundwater treatment plants are very similar in design. The plants are 3.0 to 6.0 million gallons per day capacity, iron and manganese removal plants, outfitted with induced draft aerators, chemical oxidation systems, pressure filters, distributive pumps, chlorine disinfection and fluoridation systems. The Hamilton and Montgomery County plants have emergency generators; and the Montgomery County facility also houses administrative offices and a distribution vehicle garage. All of the plants have the latest instrumentation, control and telemetry technologies, which allow them to function by either on-site or remote computer interfaces. Using an innovative fast-track, design/build delivery process termed "owner-guided design/build," these projects were successfully designed, permitted and constructed in a 16-month period from March 1996 to June 1997. A number of highly effective project management, contracting and partnering techniques were used to accomplish these results, and are described in this paper from the owner's, designer's and builder's perspectives.
