Maintenance

Maintenance recommendations are based on industry standards and experience in Reclamation facilities.
 However, equipment and situations vary greatly, and sound engineering and management judgment must be exercised when applying these recommendations.
 Other sources of information must be consulted  recommendations, unusual operating conditions, personal experience with the equipment, etc.) in conjunction with these maintenance recommendations.  

•  Preventive Maintenance Preventive maintenance (PM) is the practice of maintaining equipment on a regular schedule based on elapsed time or meter readings.
•  The intent of PM is to “prevent” maintenance problems or failures before they take place by following routine and comprehensive maintenance procedures.
•  The goal is to achieve fewer, shorter, and more predictable outages. Some advantages of PM are:
•   It is predictable, making budgeting, planning, and resource leveling possible..
•  When properly practiced, it generally prevents most major problems, thus reducing forced outages, “reactive maintenance,” and maintenance costs in general.1
•   It assures managers that equipment is being maintained.
•  It is easily understood and justified. PM does have some drawbacks:
•  It is time consuming and resource intensive.
•  It does not consider actual equipment condition when scheduling or performing the maintenance. 
•  It can cause problems in equipment in addition to solving them (e.g., damaging seals, stripping threads).
