Results and case studies

The best argument for a water cost review is what it actually returns. Below are representative results from surveys across different sectors. Figures are illustrative of the savings we typically identify; on your own site we will quantify the opportunity precisely before you commit to anything.

Manufacturing site — Midlands

A mid-sized manufacturer was drawing large volumes of mains water for once-through cooling and had never claimed a return-to-sewer allowance on water leaving in its product. The assessment recommended recirculating the cooling water and corrected the effluent basis. Combined, the measures cut annual water and effluent spend by just over a third, with the cooling investment paying back inside a year.

Identified saving: ~34% of annual spend  ·  Recovered overcharge: five figures, backdated  ·  Payback: under 12 months

Secondary school — North West

A school audit found the meter still spinning through the summer holiday — a clear sign of baseline waste. The cause was a bank of automatic urinals with no occupancy controls, plus a long-running leak on an external supply. Fitting controls and repairing the leak removed the entire holiday baseline.

Identified saving: ~41% of annual water cost  ·  Main cause: uncontrolled urinals & baseline leak  ·  Payback: same financial year

Hotel group — South Coast

A four-property hotel group had rising bills and no idea which site was responsible. Benchmarking per occupied room revealed one property running far above the others, driven by an on-site laundry with no water recovery and a pool backwashing far too often. Back-of-house measures cut the group's water spend with no change to the guest experience.

Identified saving: ~28% across the group  ·  Where: laundry recovery & pool backwash control  ·  Guest impact: none

Office landlord — London

A managing agent recharged water through the service charge with no sub-metering, so no tenant had any reason to find waste. An office audit isolated a continuous overnight flow on a vacant floor and corrected surface-water drainage charges on the car park. The recovered overcharge alone funded a decade of monitoring.

Your numbers

Every site is different, which is why we never quote a saving until we have seen your data. The free initial review is the fastest way to find out what your premises could return. Book yours here, or read about what a full review costs.

What the numbers have in common

The sites above sit in different sectors and the causes of their waste were quite different, yet the pattern behind them is the same one we see again and again. The waste was invisible from the bill alone, it had been running for a long time, and once found it was straightforward to fix. None of these clients had been careless; they simply had no way of seeing where the water went until someone looked properly.

How a saving is proven

A headline percentage is easy to print and hard to trust, so we anchor every result to the meter. Before-and-after readings, the specific measure responsible, and the payback period together turn a claim into evidence. That discipline is what lets a finance team approve the spend — and what lets you hold the saving year after year rather than watching it quietly erode.

• Savings measured against your own baseline, not an industry average
• Each result tied to a specific, identified cause
• Payback stated up front so the business case is clear
• Ongoing monitoring to make sure the saving sticks

Different sectors, one method

What links a factory, a hotel and an office landlord is not the cause of their waste but the way it was found. In each case we began with the meter data, looked for the consumption that could not be explained, and then confirmed the cause on site before recommending a fix. That order — data first, inspection second, recommendation last — is what keeps the results honest and repeatable across every sector we work in. The headline figures change; the discipline behind them does not.

Could your site be next?

If any of these stories sound familiar — a bill creeping up for no obvious reason, a site that draws water around the clock, a charge nobody has ever questioned — the chances are good that your premises holds a saving of its own. The only way to know is to look at your numbers, which is exactly what the free initial review does. We will tell you honestly whether there is enough at stake to justify a full survey, and roughly what it might return, before you commit to anything at all.
