The goal of this project was to produce a set of labor hour and frequency standards that can be applied to maintenance, repair, and replacement of equipment and appurtenences used in water and wastewater treatment. A complete list of unit operations that are used in water and wastewater treatment was compiled. Each of the unit operations listed was reviewed in detail and any equipment or appurtenance that might be necessary for that operation was listed. Each component listed was analyzed to determine the types of tasks that would have to be accomplished over the life of the component to keep it in operating condition. A seven digit numbering system was applied to the list giving each task statement a unique number. There are more than six hundred task statements for the water and wastewater treatment plants. It would be very time consuming and tedious to keep track of all the information required without the use of a computerized data base. For this project, a relational data base called d-Base III was used. A routine developed by the Architectural Engineering Department of the Pennsylvania State University for the CERL project on plumbing and electrical systems was modified for use in this project. The computer used was and IBMPCXT with a 10 megabyte hard disk. Appendix C lists the directions for use of the system including input and output of data.
