Customer Supply Pipe Losses

As distribution losses become increasingly controlled, Customer-Side Leakage (CSL) is an increasingly significant component of the leakage figures. In AMP7, the industry is focussed on tackling the issue.

The individual loss may be small, but the Leakage Run Time is often significant and when coupled with the number of CSLs, account for a significant proportion of overall losses.

Smart Metering is improving awareness times from up to 6 months (due to manual reads) and allowing analysis of Legitimate Night Use (LNU), but having identified CSL issues, both the location and repair efficiencies have led to us offering a simple, cost-effective and precise CSL location service from boundary box to property.

Our service provides the ability to:

  • Trace the route of the supply pipe from the boundary box to the property so that supply pipe records can be confirmed
  • Pinpoint the location of leaks on the supply pipe, so that the repair team can dig down accurately and without unnecessary damage to the customer’s property
  • Identify supply pipes that are constricted and require renewal

If you would like to discuss our service further, please contact us.
