Proactively investing in asset infrastructure to boost resilience

This case study describes how our Infrastructure Services teams spotted an opportunity to improve water asset infrastructure to protect future water supplies in a way that avoided disturbing the ecological balance of the local watercourse.

Uninterrupted Water Supply for 20,000 Customers Despite a Major Burst

Read how our teams worked around the clock to ensure thousands of properties were unaffected by a burst pipe expelling around 250 cubic metres of water an hour.

This case study refers to a treatment works we manage for a customer that supplies treated water to domestic and commercial properties. Every day our team performs critical activities
to ensure a consistent supply of water 24/7/365.

This water would ordinarily keep the treatment process flowing, so the knock-on effect threatened to jeopardise our ability to produce treated water for a population of around 20,000 people.
