Pipeline Asset and Risk Management System (PARMS)
 Stream Leader: Stewart
Burn
Pipeline Asset and Risk Management System (PARMS) is a suite of computer-based
models designed to assist in the management of water supply network assets.
CSIRO’s PARMS is offered exclusively by CSIRO Land and Water.
PARMS-Planning allows assessment of management and operational strategies
for both short and long-term repair and replacement of water pipelines.
PARMS-Planning can assess replacement needs based upon the predicted number
of failures in any one year, and is easily tailored to meet customer needs.
PARMS - Planning has been designed to:
- Quantify customer preferences and their effects on long-term costs
- Measure economic consequences
- Measure social costs associated with water interruptions and develop
an overall cost benefit framework
- Identify and evaluate lifecycle costs of meeting standards for water
supply continuity
- Allow assessment of the effects of different operational and management
strategies.
 Methodology - Tailored to your needs
Planning models for pipelines requires the costs of different customer
preferences and operating practices to be established. PARMS-Planning
has been developed to allow easy analysis of a range of scenarios,
such as different:
- Customers performance requirements
- Service requirements
- Operating practices
- Repair/renewal strategies required by water authorities and easy analyse.
PARMS - Planning also:
- Links to existing asset information
- Incorporates failure curves from water authorities past failure information
as well as physical models developed by CSIRO
- Includes local costing information.
Application
The PARMS-Planning model identifies assets for replacement.
Earlier models could only identify replacement strategies for a cohort
of similar pipes.
Additionally PARMS-Planning is able to assess replacement based upon the
predicted number of failures in any one year, and thus meets individual
customers’ needs.
The Planning model is used to forecast the expected annual number of failures
for each individual type and size of pipe asset for the next 30 years,
based on the age of each asset, its installation and operating conditions
and its failure history.
PARMS-Planning allows the cost implications of different management and
operational scenarios to be evaluated.
 Future PARMS components
Future modules within the PARMS suite will examine:
- Prioritisation strategies for asset replacement methods for managing high
consequence failures of critical mains
- The use and selection of condition monitoring techniques
- Different scenarios for replacement strategies and alternative risk
measures.
Implementation - Working with you
CSIRO provides water authorities with:
- Initial analysis of asset management needs
- Tailoring PARMS to suit individual needs
- Linking to existing asset database (GIS or other)
- Use of historical failure information and development of physical
failure models
- Customised costing schedules
- Ongoing support.
