Typical things we find

An unmetered supply serving student accommodation

An unbilled water bypass meter

Shadow Leakage

An unmetered feed to a student accommodation block. This was unbilled for over 10 years! There were two billed meters for the retail units, but the accommodation itself had never been billed.

Student accommodation is renowned for having problems with ‘leaky loos’. With no meter here, how would you know if there’s a leakage or wastage issue?

Shadow Demand

A school with a 51,000 litre per day leak under this classroom floor. The leak had run for over six years! No wonder the caretaker said they always had problems with slugs at this end of the school.

The savings at this school are the same as 50 standard water audits. But because it’s only one site – it’s less time-consuming, less work and less cost to get the savings.

Shadow Leakage

A nursing home with an unbilled meter. This home is split into two sections. The section on the right was billed. The section on the left, however, was unbilled. This section contains two thirds of the rooms, plus the kitchens and communal areas, and had this unbilled meter.

These are difficult to find because the billed meter masks the issue in the billing system.

Shadow Demand

A fire tank with a massive leak. Over 100,000 litres per day was leaking into the bottom of the structure and down the drain.

Enough water was being wasted here to serve 200 households – in an area designated as severely water stressed by the Environment Agency.

Shadow Leakage

A fruit farm with an unbilled meter. This farm had a combination meter. The main meter was billed, but the bypass meter was not.

This supply has high seasonal use, with fruit pickers occupying 91 caravans throughout the Summer. With an extra 450 people on site, there will be a seasonal increase in night use that you'll want to capture – otherwise it will go on your leakage.

Testimonials

Highlow Water’s analysis has helped us to uncover significant volumes of unaccounted-for water and high use at non-household properties. We’ve been able to focus the analysis into areas where it helps us the most.

The analysis finds issues at properties that would otherwise fly under the radar and are not obvious from simple analysis of the data. Highlow’s approach turns these hidden issues into low-hanging fruit, which helps us against our business targets.

SEW used High Low Water to help us identify which schools were using more water than they should be so that they could be targeted through our water efficiency work.

Ben and the High Low team helped us identify some Super High using schools. Ben was also really helpful in visiting the schools and helped these schools find leaks and fix them quickly, helping them save money and water! Thank you for the work you did-it helped us be specific in where we target!

I am pleased to provide this reference regarding our ongoing partnership with Highlow on the current water efficiency trial.

From the outset, Highlow has demonstrated exceptional professionalism and a proactive, collaborative approach. Their team has worked closely with ours to design and deliver each phase of the project, ensuring clear communication, careful planning, and smooth coordination across all stakeholders.

Although the trial is still in progress, the process so far has been well managed and has given us confidence in both the methodology and Highlow’s expertise. They have been responsive to any operational challenges and consistently maintain high standards of safety, accuracy, and customer engagement.

Based on our experience to date, we have every confidence in Highlow’s ability to see the project through successfully and would recommend them to other water companies considering a similar initiative.
