    An evaluation of a water treatment plant with improved overall effectiveness as an objective
    Homsi, Ibrahim J. (Virginia Tech, 1995-12-05)
    The XYZ water Authority (Authority) supplies a population of approximately one million people with drinking water. This water is being produced by three water treatment plants and several independent well sites. The River water Treatment Plant (WTP), the Authority's largest and most modern of all three plants has been experiencing, over a period of ten years, severe and premature equipment failures which are causing process interruptions, production losses and high maintenance cost. These failures were attributed to lack of proper operations and maintenance procedures and practices. In an effort to rectify these maintenance and support problems, the Authority initiated this study for evaluating the current operations and maintenance (O&M) activities at the River WTP. The purpose of this project is to identify the major deficiencies with the current O&M program and to recommend an approach for continuous improvement of plant performance. These recommendations employ some Total Productive Maintenance (TPM) concepts initially introduced by Japan. TPM is an integrated life-cycle approach related to production equipment. Investigations of the water industry revealed that until this date, the introduction and complete implementation of TPM to maintain equipment associated with water treatment in the U.S. has not been fully utilized. It was also determined by this study that a prerequisite for successful implementation of TPM is a computerized maintenance management system (CMMS) to be utilized for managing maintenance information. A brief description and implementation procedures of CMMS is also included in this report.

    The Fairfax County Water Authority response to the Colonial oil spill of March 28, 1993
    Bonacquisti, Thomas P. (Virginia Tech, 1994-04-18)
    The Fairfax County Water Authority (FCW A) is one of the largest water purveyors in Virginia, producing an average of 111 million gallons of water per day for approximately 960,000 people. Located in Northern Virginia, FCW A supplies drinking water to Fairfax, Prince William, and Loudoun Counties, the Town of Herndon, the City of Alexandria, and several federal institutions within the area. The Potomac River and the Occoquan Reservoir constitute the raw surface water supplies for the service area. On March 28, 1993, a 36-inch oil transportation line ruptured, spilling in excess of 400,000 gallons of No.2 fuel oil in the vicinity of Reston, Virginia. This massive spill severely contaminated the Potomac River and forced a complete shutdown of FCWA's Corbalis Water Treatment Plant (WTP) for 13 days. Since the Corbalis WTP normally meets 50 percent of the water demand, production from FCW A's other treatment facilities, drawing from the Occoquan Reservoir, had to be dramatically increased during a period of unusually harsh raw water conditions.
