The most important thing is to complete these types of maintenance, no matter what they are titled. Different names or definitions of maintenance can be used, and systems might combine categories of maintenance in different ways than described below. Maintenance falls into the broad categories listed below. Maintenance involves those activities that help keep the assets in good working order, so they will operate as intended. The collection of data in this phase assists in decision making for all phases of the asset’s life. In this phase, all maintenance activities are performed and tracked. The purpose of the maintenance phase is to ensure the asset is fully functional and performs optimally until it reaches the end of its useful life.

The operations plan is a manual for operating the system. It should define how resources (personnel, financial and physical) will be allocated to achieve the Level of Service goals. The system should have a plan in place that lays out the who, what, when, and how of the daily operations. Passive assets are unlikely to need any change in operation, while active assets or those that are a bit of both might require changes. These distinctions become most important in alternate and emergency operating procedures. In this case, the asset becomes an active asset. However, if a major pipe break occurred, the valve would need to be closed with human intervention. The valve is normally in an open or closed position and functions as a passive asset since no intervention is required for it to stay in this position. An example would be an isolation valve in a water distribution system. There are also some assets that are both passive and active.

These types of assets include pumps, chlorinators, scrapers, and chemical addition systems. If an asset is active, it will need human interaction or control technology to start/stop it and adjust its operation to meet the conditions and requirements at the time. These types of assets include categories such as pipe, storage tanks, utility access holes, and many green assets, including bioswales and pervious pavement. If an asset is passive, it does not require regular human interaction for it to do its job. Personnel should be familiar with all three types of procedures, or they should know where they can find the procedures when needed in resources such as in a book, online, or in a shared site.Īsset operations can be passive or active. Emergency operating procedures – These plans are used in response to a specific event that poses an immediate risk to health, life, property, or the environment.This might be due to maintenance or other activities that require it.

Alternate operating procedures – Procedures used when the system is not being operated in a routine fashion.

Standard operating procedures – Operations carried out routinely to ensure the system is performing as expected.

Operations, or operational activities, can be classified into three categories: In this phase, operation activities are performed and tracked. The purpose of the operations phase is to ensure the asset is operated as it was intended, within design specifications, with maximum uptime until it reaches the end of its useful life. Otherwise, it will be difficult to optimize or schedule maintenance so it causes the least disruption in operations. It is imperative that the operations and maintenance personnel communicate regularly. Maintenance and operation are not always completed by the same personnel. However, the two activities usually do not happen at the same time - for example, an asset might be taken out of service for maintenance. Therefore, when the operations plan for an asset is developed, the maintenance plan also needs to be considered. How assets are operated will impact how assets need to be maintained and vice versa. Operation and maintenance are often discussed as one activity (i.e., O&M), but they are two, different, but interrelated, activities.
