Ego Restaurant | The Holly Bush

When unexplained water costs began impacting margins at Ego Restaurant The Holly Bush, the issue was invisible to the team on site.

There were no obvious bursts, no flooding, and no visible pipe failures. However, hidden leakage and overnight wastage were quietly draining both water and profit.

Using LeakNet smart metering technology, Quensus identified the problem, implemented targeted efficiency upgrades, and delivered a measurable reduction in consumption within months.

‍

The Challenge

LeakNet smart metering detected unusually high overnight consumption while the restaurant was closed.

The system recorded a significant abnormal spike. Flow rates reached 71.7 litres per minute for several hours overnight.

This level of continuous flow outside operational hours indicated substantial hidden leakage or uncontrolled usage.

The financial impact was material:

• Approximately £875 per month in unbudgeted water costs
• Total monthly water spend reaching around £1,450
• No clear visibility on where the losses were occurring

Without real time monitoring, the issue would likely have continued undetected.

‍

The Solution

Quensus installed smart monitoring equipment on both the 1 inch hot and cold water mains within the basement boiler room.

The system provided:

• Continuous flow monitoring
• Overnight usage visibility
• Data driven insight into abnormal patterns
• Clear benchmarking for expected operational consumption

‍

Following data analysis, Quensus recommended a structured efficiency upgrade plan:

1. Repair of five leaking toilets
2. Upgrade to dual flush systems to reduce ongoing consumption
3. Installation of an automatic valve programmed to shut off the mains water between 2 AM and 8 AM

This combination addressed both active leakage and future behavioural or operational wastage.

‍

The Results

The impact was immediate and measurable.

• Water costs reduced from approximately £1,450 in December 2018
• Down to £635 by July 2019
• Representing a 57% reduction in total water spend

The return on investment was rapid:

• Most recommended upgrades achieved payback in just 2.5 months
• Ongoing savings continued beyond the initial recovery period
• Reduced exposure to future hidden leaks

‍

Strategic Impact

Beyond the direct cost saving, the project delivered:

• Data driven control over water usage
• Reduced risk of major leak events
• Protection of operational margins
• Long term sustainability improvements

‍

This case demonstrates how smart monitoring combined with targeted physical upgrades can transform water management from reactive maintenance into proactive asset control.
