Leak Detection

Mark Quartermaine has completed leak detection training presented by Wide Bay Water Corporation Queensland, which included:

  • Theory and practice of acoustic sounding
  • Theory and practice of acoustic logging
  • Importing GIS maps
  • Use of leak detection software
  • Correlation of leak noise recordings.

Surveyors are conducted using leak noise loggers to detect leaks when the system is quiet. Leaks can be located on longer pipelines and information logged using PC based leak correlators.

Leak Search can carry out

  • ALD surveys and water audits
  • Data gathering for hydraulic modelling
  • Surveys of Sewer Rising Mains
  • Investigations of Trunk Distribution Mains
  • Investigations of bore field water loss
  • Utility Mapping
  • Reporting on the condition of valves and mains
  • Investigations for unauthorised water use
  • Investigations for residential and commercial water loss.

Leak Search methodologies and data processes are an integral part of a full “water audit”. At the end of an investigation, a technical report is produced detailing the water loss. Satellite phones are used to communicate anywhere in Australia.

ALD Survey, Water Audit in progress

Vacuum Excavation for Sub-surface Utility Engineering

Non-destructive digging (NDD), pot holing or soft dig is the safest excavation and preferred method.

Temporary bypass for Pressure logging - 50mm temporary bypass for minimum night flow calculations

Sample flow data

(Dewatering pump) Cast iron fitting leaking at flange flow loss estimate 20 L/min = 28.8 kL /day

Leak correlation flow estimate 5L/min
