UK Water Industry Adopts New Tech to Fight Drought Risks
The topic is trending due to increasing water stress in England, where nearly three-quarters of the country is facing drought conditions. In response, Southern Water is deploying new acoustic sensor technology to find and fix leaks in ageing infrastructure.
What happened
- Earlier
A 650 km UK trial of Lightsonic's technology saved over four million litres of water daily [1], [2].
- Recent
Southern Water announced a partnership with Lightsonic to monitor drinking water networks using Openreach fibre optics [1].
What you need to know
Roughly 2.6 billion litres of water leak from England's network every day [1].
About 60% of England's water mains are older than 45 years [1].
The new system uses existing telecommunications cables to detect vibrations from leaks [1], [2].
The technology helps utilities prioritise repairs by categorising leak severity [1].
It is not confirmed how many total kilometres of the Southern Water network will be covered by this technology.
Background
Southern England is one of the most water-stressed areas in the UK. This puts significant pressure on utilities to maintain supplies while dealing with climate changes [1].
The water industry is facing challenges from ageing infrastructure, with some mains exceeding 100 years in age [1].
Southern Water serves 2.7 million drinking water customers and 4.8 million wastewater customers across the Isle of Wight, Hampshire, Kent, and Sussex [1].
Questions people ask
How does the leak detection technology work?
It turns existing fibre optic cables into acoustic sensors that pick up sounds and vibrations from leaking pipes [1].
Why is this being implemented now?
It is part of a strategy to build drought resilience and meet Ofwat's 2030 targets amid worsening water shortages [1].
