11.3.4.3
Maintenance Personnel. Another component of an effective maintenance
management system is efficient organization of maintenance personnel. This includes
providing adequate staffing, developing job descriptions and an organizational chart,
providing maintenance training programs, and holding periodic staff meetings.
Job descriptions are often developed for use in assessing the skill level
required to perform particular tasks in a maintenance program. Depending on the size
of the facility, complexity of equipment, and size of the maintenance department,
various skill levels may be required (for example, Operator I and II, Mechanic,
Electrician, etc.). In many facilities, specialized equipment maintenance may require
the use of outside contractors.
11.3.5
Spare Parts and Stock Control. Keep sufficient types and quantities of
materials and stock on hand to ensure practical, economical, and continuous service.
A review of the equipment and the manufacturers' recommendations will aid in
determining which spare parts and miscellaneous supplies should be included in the
inventory.
11.3.5.1
Expendable Stock. Stock levels for expendable items used at a fairly
uniform rate (such as pump packing, treatment chemicals, and laboratory reagents) are
based on maintenance experience and operating reports. However, levels may be
modified for reasons of economy. Thus, savings can sometimes result if treatment
chemicals are bought in large quantities.
11.3.5.2
Standby Items. Seldom-used materials needed to safeguard health,
ensure uninterrupted operation of installation facilities, or prevent destruction of
property are classed as standby items. Typical examples are chlorinator parts, such as
a spare flowmeter, auxiliary chlorine valves, and cylinder connections. Hold materials
to be stocked as standby items to a minimum, based on a detailed study of the water
supply system. Consider these issues in setting up stocks of standby items:
a)
Non-critical parts immediately available from nearby installations,
municipalities, or supply houses are not stocked. Critcal parts are stocked.
b)
Much repair work at pumping stations and treatment plants can be
anticipated, and parts for these repairs can be secured when needed.
c)
Only major sizes of pipe and fittings are stocked in large amounts.
d)
If the plant has several similar units, parts that are interchangeable
need not be stocked for each unit.
