The challenge
The water serving an English luxury private estate had a long history of fouling and deposits building up in its borehole and distribution pipework, and the conventional chemical treatment in place was not clearing it.
Deposits on pipe walls are where waterborne pathogens shelter and re-grow, so for an estate carrying a duty of care over its water, a system that never comes properly clean is a standing Legionella risk, not a cosmetic problem.
What we did
We introduced a disinfection regime aimed at the pipework itself rather than only the water it carried, dosed continuously at a low concentration across the system, rather than relying on the heavier chemical load the estate had been using.
Over a ten-week trial, just 62.5 litres treated 1.6 million litres of water, a fraction of the previous chemical volume, and the water was tested by the estate's local water-authority laboratory.
The result
Brought back under control, with far less chemistry.
The pipework was visibly clear, and the result was achieved with a fraction of the chemical the estate had relied on.
The water was tested by the estate's local water-authority laboratory, an independent check on the pathogen counts across the trial.
Why it matters
For estates, hotels and any operator carrying a water-safety duty, the inside of the pipework is the hardest part of the system to control and the easiest to ignore. This shows it can be brought back under control, and kept there, with less chemistry in the water, not more.
