Develop operation and maintenance costs associated with <br /> partial automation and control verses maximum practical <br /> automation and control . <br /> 6. Identify property needs. <br /> H. Horizontal Collector Well Source Feasibility Study <br /> 1. Review existing published and other available data regarding <br /> the geological and shallow ground water conditions along and <br /> under Lake Decatur and the Sangamon River basin. <br /> 2. Evaluate to determine if sufficient coarser-grained <br /> unconsolidated material exists with sufficient hydraulic <br /> conductivity and recharge to produce continuously up to 24 <br /> million gallons per day. <br /> 3. Identify potential sites for horizontal collector wells. <br /> 4. Prepare a draft favorability evaluation which summarizes the <br /> information and data evaluation and provides an opinion <br /> regarding the success for developing the horizontal collector <br /> well as a total or supplemental raw water source for the <br /> plant and an opinion of probable construction costs based on <br /> similar projects. <br /> SLN3:023 A-6 April 1, 1991 <br />
