Course overview
This course was developed by WRc to enable delegates to understand how the N1 exponent relates to water loss management; and to plan for, carry out, and analyse data from N1 field tests. Knowledge, skills, and techniques gained will ultimately allow leakage teams to sustain an optimised and resilient water supply system. Upon course completion, participants will be able to:
- Understand pressure zones in the supply system and how the N1 exponent relates to pressure and leakage, as well as its impact on water loss strategies
- Identify best practice for implementing a successful N1 test which draws upon lessons learned and common challenges
- Use data to select DMAs and pressure zones as targets for N1 testing
- Create a comprehensive plan for N1 testing, including zone selection, scheduling, resource allocation, and risk management
- Prepare and conduct a safe and accurate N1 field test
- Analyse and interpret N1 test results and use this data to inform pressure management, leak detection, and repair prioritisation
- Establish ongoing monitoring practices to sustain system efficiency and resilience
Who can benefit?
Delegates may include new starters to the water leakage field. Additionally, new recruits to leakage teams to ensure a standardised level of knowledge and training, thus consistency of operations.
