Pumps Tab

The Pumps tab enables users to document a pump's location and other attributes, including its manufacturer, model number, size, serial number, and classification.  An agency can also record the pump installation date and project number.  The tab records pump specifications as well, such as its various diameters, elevations, and part types. Several fields with a unique purpose are defined in the table below.

Field Name

Definition

Location

The location of the pump slot from the Pump Station Inventory, Pumps tab. (Read-only.) This field remains blank if:

  • The slot in which this pump is installed does not have a defined location

    OR

  • The pump is not currently installed in a pump slot.

Pump Size (in)

The physical dimensions of the pump unit.

Pump Classification

The category of pump (e.g., booster, wet well, above ground, etc.).

Pump Capac (gpm)

The capacity, in gallons per minute, of the pump at the specified operating point.

Total Dyn Head (ft)

The total head, in feet, at the specified operating point.

Impeller Dia (in)

The size, in inches, of the impeller installed in the pump.

Number of Stages

Usually equal to the number of impellers installed in a pump.

Priming Type

The type of priming used on the pump (e.g., flooded suction, vacuum, water, etc.).

Pump Controller

The method used to control the pump (i.e., local or remote).

SS End Type

The type of end on the suction side of the pump.

SS End Dia (in)

The diameter, in inches, of the pump's inlet.

SS C/L Elev (ft)

The elevation, in feet, of the suction piping centerline.

DS End Type

The type of end on the discharge side of the pipe.

DS End Dia (in)

The diameter, in inches, of the pump's outlet.

DS C/L Elev (ft)

The elevation, in feet, of the discharge piping centerline.

Risk Calculation

Risk calculations are a way for agencies to evaluate where potential weak spots in their infrastructure are.

Criticality

Rates how important the asset is. This rating should be a whole number based on a scale that the agency uses. A higher number means more risk.

Example: On a scale of 1 to 100 this asset is pretty import so it has a Criticality score of 85.

Probability of Failure

Rates how likely the asset is to fail. This rating should be less than one because it represents a percentage.

Example: This asset will only fail about 5% of the time so it has a Probability of Failure of (5/100) = .05

Mitigation

Rates any factors that have been put into place to mitigate the failure of the asset. This rating should be less than one because it represents a percentage.

Example: To offset the failure of this asset we have a backup, though it will only make up for about 30% of the loss. This asset has a mitigation score of (30/100) = .3

Risk

Represents how much risk the asset represents. Calculated based on: (Consequence of Failure x Probability of Failure x Mitigation).

Example: This asset represents a 85 x .05 x .3 = 1.275 risk to the system.
