Part of Planning Inspectorate accepted a project for DCO examination concerning water supply from rivers in Hampshire.

How could low river levels in the River Test affect Openreach's infrastructure usage?

Likely What happens if… A possibility worth considering, not a forecast.

Openreach's fibre network is being utilized for Southern Water's drought resilience efforts The threat of water shortages, driven by low river levels in the River Test, is prompting Southern Water to strengthen its drought resilience. To achieve this, the company is trialling the Lightsonic system in Hampshire. This technology uses fibre optic cables and machine learning to detect leaks efficiently. Crucially, the Lightsonic system relies on utilizing Openreach’s existing underground fibre network to continuously monitor the water pipes.

Why it matters

For Openreach, the utilization of its existing infrastructure by Southern Water for this specific, large-scale water management project represents a concrete operational application of its network. This demonstrates the utility of its fibre assets beyond traditional telecommunications, potentially opening new avenues for infrastructure partnerships and service deployment in response to climate pressures.

This initiative is part of a broader industry trend where aging infrastructure and mounting climate pressure are converging, causing major water stress. Southern Water has already identified and repaired nearly 15,000 leaks across its region since January, showing a commitment to using innovative techniques to secure supply.

What we don't know yet

  • How many leaks are expected to be detected using the Lightsonic system in the Hampshire trial?
  • What is the projected long-term cost saving for Southern Water from this technology?

What would change this answer

Southern Water expands the Lightsonic trial beyond HampshireThis would increase the scale and duration of Openreach's network utilization for water monitoring across the UK.
The River Test flow levels stabilize or increase significantlyThe immediate pressure on Southern Water to reduce reliance on the river and implement leak detection would diminish.
