11.3.1.4
Major Overhaul and Repairs. As a rule, major overhaul and repairs are
not made by operating personnel. This work is usually performed under contract.
11.3.2
Personnel. It is generally best if well-trained personnel perform
inspections, repairs, and preventive maintenance tasks. Personnel assigned to these
tasks should possess a thorough knowledge of the functions and operations of the
equipment and the procedures for servicing it safely.
11.3.3
Maintenance Information. Water supply system personnel need ready
access to equipment O&M information. Keep this information on file and update it as
necessary. The best sources of maintenance information are the manufacturers'
instruction manuals provided with each piece of equipment. This material should be
bound and organized according to equipment type and be kept in good order for quick
reference. The following information is typically included in these manuals: descriptive
literature (catalog cuts and data sheets); parts lists; instructions for installation,
operation, maintenance, and repair; performance data (i.e., pump performance curves);
electrical diagrams; and schedules of required lubricants and chemicals. It is normally
recommended that operating personnel be familiar with each piece of equipment
through careful examination of these instruction manuals.
The material contained in this handbook is designed as a general
overview of maintenance requirements and may not contain answers for specific
maintenance questions. Consult the manufacturers' instruction manuals for specific
maintenance information. The specifications, shop drawings, and as-built drawings,
which should also be kept on file, show dimensions of each piece of equipment and
provide information on pipe sizes and materials, valve types, equipment types, etc.
They are available to plant personnel if the schematic drawings and valve and
equipment schedules in this manual do not provide sufficient information.
11.3.4
Maintenance Management System. Regularly scheduled preventive
maintenance is essential for keeping equipment in good running order. Daily tasks
may be incorporated into the sampling and laboratory testing routine to make the most
efficient use of the operator's time. If possible, perform routine tasks on the same day
of the week or month to avoid confusion about when they were last performed. For
example, each Monday can be set aside for performing weekly tasks, and the first
Tuesday of the month can be set aside for monthly tasks. Annual lubrication can be
performed during January.
Since operating personnel cannot be expected to remember the service
requirements for every piece of equipment, a system of preventive maintenance is
essential. To ensure the system is successfully implemented and maintained, it should
