Use leakage detection techniques to identify the location of water loss
Overview
This Standard is about using leakage detection techniques to identify the location of water loss. Techniques can include, but are not restricted to, acoustic, flow and pressure, step testing or visual. This includes selecting suitable single or combinations of leakage detection methods, resource planning, setting up and configuring equipment, using results to identify location, prioritising the urgency of leakage situations, recording information and make sure the relevant people, including customers, are provided with updates. Health, safety and hygiene procedures should be followed at all times.
This Standard is for anyone who uses leakage detection techniques to identify the location of water loss.
Performance Criteria
You must be able to:
obtain and analyse current information from existing records and data
select leakage detection methods that are appropriate for the condition and type of distribution infrastructure and its current characteristics
select methods and techniques that comply with health, safety and environmental considerations whilst minimising effects on water supply, water quality and customers
specify, and sequence, the extent and combination of leakage detection methods and techniques which will produce the most effective leakage detection activity
use information from reliable sources to determine equipment and resource requirements, availability and cost effectiveness
establish contingency plans in line with organisational procedures for situations where potential problems might occur
confirm notification procedures are put in place in accordance with organisational requirements
make sure those affected by testing are informed of the time and duration of tests and their effect on water supply before they start
check equipment for leak detection is in working order and safe to use
connect, set up and configure equipment in line with manufacturers’ instructions
use results to identify and verify accurate location of leakage
dismantle, clean and return equipment to storage in accordance with organisational requirements
mark the position of leakage in accordance with organisational requirements
record and report the position of leakage, including any local environmental or traffic conditions, in accordance with organisational requirements
determine and advise on urgency and acceptable timescales for dealing with identified water loss in compliance with quantity, rate of water loss and organisational service standards
determine the options for disruption to supply and potential extent of disruption that is necessary to deal with identified water loss situations
report relevant details to appropriate people about detection methods and the need for any further investigation
follow safe working and hygiene processes in accordance with approved procedures and practices
