Water Pump Station Models

ARMS Reliability Engineers were engaged by Watercare Services Limited to undertake a RAMS analysis of Sewer Pump Stations which would address the dominant failure modes and provide an effective maintenance plan and generate budget and performance predictions.

The pump stations completed were:

• DPS016 - a large critical station
• DPS015 - a medium sized medium criticality station
• DPS012 - a small sized low criticality station

The approach taken for this analysis was to build a Failure Mode Effect and Criticality Analysis (FMECA) model that represented the likely failure modes, provides an assessment of the Effects of Failure, and to allow the most effective maintenance tasks to be chosen. Once the maintenance tasks were chosen, the information was loaded into an Availability model so that the predicted spares can be generated.

These models were used as templates to allow rapid building of stations across the network.

Water Treatment Plant System Availability model

ARMS Reliability Engineers were engaged by Watercare Services Limited to undertake an Availability analysis of a water treatment plant which would predict system performance on the basis of maintenance plans derived.

Water Pipe Network Criticality Model

ARMS Reliability Engineers were engaged by Watercare Services Limited to undertake a high level criticality model of their entire water pipe network including dams, reservoirs and treatment plants.
This was a Reliability Block Diagram model which generated a criticality ranking of elements within the network in order to assist long term asset planning.

Ongoing Support

Watercare continue to utilize the RCMCost and AvSim+ software programs to review and optimise their maintenance and then evaluate system performance. ARMS provide ongoing support to the Watercare organisation ranging from periodic support meetings, remote model review rapid model building, and training
