CP348  Pumps - Maintenance and Replacement to Suit Asset Management

The size and type of pumps used for different purposes in the water industry varies enormously; as does the costs of failure. Managing such a large stock of variable pump types is extremely complex and demanding. To be effectively managed, pumps need to be grouped and allocated their own programme, according to factors such as:

  • Consequential risks of failure.
  • Management effort scaled by whole life cost.

  • The pump duty; steady intermittent and variable.
  • Maintenance/replacement schedules.

This project will deliver cost-effective manageable plans for each pump group based on operational stress envelopes, using operating data such as: hours run; start/stop frequency; and pumped material. The management programme will also incorporate key pump management factors such as whole life costs (WLC) - including carbon, proactive and reactive maintenance, monitoring, stress factors in service and service failure costs.


  • Potentially significant savings.
  • Mechanism to include carbon considerations in pump management.
  • Clearly defined management methods for different pump groups.

Work programme

Bringing in specialist expertise from the Pump Centre, this project will:

  1. Review and build on recent relevant pump management work, including UKWIR projects on data collection (WIDER) and deterioration models.
  2. Set the categories of pumps by: type; duty; size; maintenance and operating regime; and failure data. This will include stress factors e.g. start/stop rates, run time and severe duty.
  3. Define pump groups, and for each pump group create the WLC (including consequences of failure).
  4. Identify pump management elements and assign costs to them, including, scheduled/unscheduled maintenance, refurbishment, and pump monitoring methods.
  5. Build WLC models, with a carbon price element, for each of the pump groups and calibrate with client data.
  6. Develop a stress envelope, linking run time, start/stop rate and operating regime to the timescale to replace the asset.
  7. Develop a matrix of management operations against pump groups showing WLC benefits.
  8. Produce, in consultation with participants, a pump management implementation plan.

Project Output

  • Interim report on the pump groups and estimated WLC.
  • Consolidated report on pump management by groups, and the research. into the costs of maintenance, monitoring and refurbishment.
  • Implementation plan.
  • Dissemination seminar.
