22、ation, 146xiPrefaceSuccess in any project requires careful planning, design, imple-mentation, and monitoring. Establishing an effective mainte-nance program is no different. Many significant advances have been made in recent years in maintenance management systems, including the introduction of a nu

23、mber of software packages that simplify the task of designing a good maintenance operation and the application of geographic information system and global position-ing system (GIS/GPS) technology to facilitate the location of plant equipment and distribution system components. Still, the fundamental

24、 requirements for establishing an effective program remain the same. A maintenance manager who initiates a project to establish or improve a program must:Develop a clear statement of the scope of the work with cost 1. estimates.Sell the merits of the project to senior management.2. Carefully design

25、the program to include all necessary elements, 3. including planning for future expansion.Solicit the cooperation and recommendations of upper 4. management, operations personnel, and field maintenance technicians.Develop an implementation plan and schedule.5. Plan techniques for monitoring and revi

26、ewing the program 6. after implementation.xii |MAINTENANCE MANAGEMENT FOR WATER UTILITIESThe establishment or improvement of a maintenance program must be a high priority for any maintenance manager. The benefits to a water utility of an effective maintenance program are well established, and senior

27、 managers generally support implementing improved programs for maintenance. The maintenance manager and staff are key members of a utility staff who contribute to the effective operation of a water utility by ensuring that equipment runs smoothly and facilities and grounds are safe and functional wo

28、rkspaces. This book was prepared to provide guidelines to help water utility maintenance managers develop and analyze their maintenance man-agement programs. The text systematically covers the primary com-ponents of effective maintenance management and suggests actions that a maintenance manager can

29、 take to improve the operation of the maintenance section.While this book continues to emphasize the importance of per-forming preventive maintenance and of carefully planning new and modified maintenance systems, this edition introduces newer concepts involving the use of GPS technology and asset m

30、anagement. In par-ticular, the application of computer technology has expanded from generating and tracking work to integrating maintenance data with the utilitys financial and inventory systems. The use of the Internet to pro-vide training for maintenance staff is also introduced as an additional r

31、esource for maintenance managers to consider.The author thanks manuscript reviewers Kenneth C. Morgan, PE, Water Distribution Superintendent, City of Phoenix, Ariz.; and Robert Garcia, City of Peoria, Ariz. The author also wishes to acknowledge the important contribution that maintenance managers an

32、d techni-cians make to the success of their water utility. This acknowledgment extends to those operations staff, particularly in smaller water utilities, who perform many of the maintenance tasks that are essential for the efficient operation of a water utility.1CHAPTER 1The Need for MaintenanceWhe

33、n a piece of equipment is first placed in service, it gener-ally operates near its maximum efficiency. For example, a new automobile, assembled with new parts, is at its operating peak, with the engine running smoothly and according to the specifications of the designers and manufacturers. The shock

34、 absorbers, springs, and tires produce the best ride that the vehicle is capable of delivering.The same principle applies to a water pumpset and its auxiliary equipment. Assuming proper design, construction, and installation, the volume of water pumped immediately after a system has been com-mission

35、ed is at or near its design capacity. This principle holds true whether the equipment for transmitting the water is a hand pump located in a village or farm or a 50-mgd centrifugal pumpset providing water to a large community.Also, of course, all equipment with moving parts eventually wears and must

36、 be replaced. The owner of the car, the farm with the hand pump, and the utility using large-capacity pumping equipment all must recognize this fact and develop plans to correct inevitable equipment wear.A water utility is among the most capital intensive of all utilities. A utility of any size must

37、 allocate sufficient resources to perform those maintenance functions needed to protect its investment in equipment. In larger utilities, a separate maintenance group is usually required; 2 |MAINTENANCE MANAGEMENT FOR WATER UTILITIESfor smaller utilities, staff, for example, plant operators, may per

38、form all duties critical to the operation and maintenance of the system. Only through effective maintenance management can a utility fulfill its responsibility to provide high-quality water to the community it serves.Role of the Maintenance DepartmentA water utilitys primary function is to provide s

39、afe, high-quality water to its customers in sufficient quantities and at a reasonable cost. The performance of the utilitys maintenance department plays a key role in the success of this endeavor. In general, the maintenance group provides support services to other departments within the organiza-ti

40、on. Maintenance is responsible for keeping the equipment, vehicles, and structures of the utility in good operating condition. The services provided by maintenance personnel range from routine tasks such as replacing light bulbs to critical ones such as repairing equipment neces-sary for production

41、of finished water. Whatever the nature of the work, efficient completion of these tasks requires a planned approach.ResponsibilitiesThe specific responsibilities of the maintenance group include the following:Repairs to equipment, vehicles, distribution system scomponents, and buildingsplanning and

42、executing repairs to restore the equipment and structures to acceptable standardsPreventive maintenance (PM)developing and implementing sa program of regularly scheduled work designed to maintain equipment operation and prevent major problems.

47、tructure needing maintenance.Balancing Maintenance RequirementsA large utilitys maintenance department is frequently organized into four sections to accommodate different O chemical-feed equipment; flocculation, sedimentation, and filtration units; process instrumentation devices (such as flowmeters

48、 and other telemetry components); and transformers, motor control centers, and protec-tive relays.Since E/M equipment incorporates a multitude of moving parts (e.g., bearings and contacts) subject to wear, it requires effective PM for reliable and economical operation of treatment plants and pumping

49、 stations. However, PM is not cost-effective for all E/M equipmentsome equipment is generally operated until it fails. For example, unless a fractional horsepower motor is driving a critical piece of equipment, PM for it is probably not cost-effective. The motor will be replaced when it fails. Even under a good PM program, other equipment will fail on occasion simply because of faulty components. Thus, pr
