Leak detection on a major UK university campus
Leak detection
A leading UK university identified unusually high water usage on its campus network and suspected a leak. With a dozen interconnected buildings supplied by a shared pipe, the challenge was to pinpoint the source of the problem quickly to minimise both water loss and financial impact.
The challenge
Water meters indicated a suspected leak of around 1,000 litres per hour. Left unresolved, such a leak would waste 24,000 litres of water per day – the equivalent of almost ten average UK households’ daily consumption. At current water and wastewater rates, the university stood to incur tens of thousands of pounds in unnecessary costs annually, not to mention the environmental impact.
Ecoprod’s engineers began with a site-wide survey and detailed analysis of usage and leakage graphs, narrowing down the likely location of the leak.
The next stage was to insert a T-section and hydrant connection to allow for CCTV under pressure. This investigation revealed stones and partial blockages within the pipework in the area where the leak was suspected.
This approach provided confirmation of the issue’s location and allowed the university to plan remediation with minimal unnecessary excavation.
Financial and environmental impact
A leak of this scale – 1,000 litres per hour – could cost a large institution upwards of £50,000–£100,000 per year in wasted water and sewerage charges, depending on tariff. By locating and addressing the leak, the university not only prevented ongoing financial loss but also reduced unnecessary strain on water resources.
This case study highlights the importance of specialist water leak detection and investigation for large estates such as universities, where supply networks are complex and water loss can escalate rapidly. By working with experienced engineers, institutions can reduce costs, protect infrastructure, and demonstrate environmental responsibility.
