Records of Maintenance Performed Records must be kept indicating which maintenance tasks have been performed and when. This is helpful for two reasons. First, it is imperative to verify the completion of each maintenance task. Second, to schedule future maintenance activities or to verify the condition of certain equipment, it is always helpful to be able to refer back to the record of past maintenance performed. All tanks should be inspected once per year. Technical Resources Manufacturer’s maintenance specifications do not always provide complete information on all maintenance tasks. Certain general maintenance tasks are not covered in detail in manufacturer’s maintenance

1-13 Introduction to Wastewater Management manuals, and many general maintenance tasks are not addressed in manufacturer’s information at all. Tools and Equipment Every wastewater system must have suitable tools and the required specialized equipment available to perform maintenance. These tools and equipment should be of good quality, because they are likely to be used for many years. Spare Parts Inventory It is important to maintain an inventory of spare parts required for preventive maintenance, as well as for corrective and emergency maintenance. The initial inventory must be developed based on the requirements of each preventive maintenance task. Procedures also should be implemented to make sure that parts are replaced in the inventory as they are used. Database management of spare parts inventories is usually necessary in larger utilities. Personnel Training Even a well-developed maintenance program with a full staff for implementation will not be able to complete the required work unless the staff are trained in both how to carry out the maintenance program and in the precise skills required to perform specific maintenance tasks. If the maintenance program has not been developed internally, the consultant or entity that developed it should be required to provide training in its implementation. Budgeting for Maintenance Budgeting for maintenance will require that sufficient funding is available for the following: Preventive Maintenance—Operating budget Labor (staff time, person hours) Parts and supplies Equipment Emergency Maintenance—Operations reserve account Labor (overtime) Materials, parts, supplies Replacement equipment Contractors Equipment Replacement—Capital reserve account Evaluation and design Labor Equipment cost Contractors Estimating Staff Hours for Various Maintenance Functions (Task Analysis) Sufficient labor must be available and funded for preventive maintenance functions. A good preventive maintenance program will document the schedule and work plan for each maintenance function. This schedule serves as the basis for estimating the labor requirements for preventive maintenance.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
