A factory draws continuously, so a leak does not stand out. It becomes part of the baseline and stays there until somebody compares the meter against what production should actually use.

- Buried reticulation between buildings, installed in phases with no accurate as-built drawing.
- Steam and condensate lines, where a failed trap wastes both water and energy continuously.
- Cooling circuits and make-up water, topping up automatically and hiding the loss entirely.
- Wash-down and CIP systems running at high volume, so a fault disappears into normal usage.
- Compressed air and gas lines, a separate loss that the same survey methods find.
- Effluent and trade waste lines under hardstanding.
Scheduling Around Production
The cleanest data comes from a site at rest, so testing is normally booked into a planned shutdown or an overnight window. Night-line analysis establishes what the site draws when nothing should be running, and that figure alone often justifies the survey before anything is located.

These are indicative market ranges, not a quotation. They are compiled from published South African leak detection and plumbing pricing to give you a starting point for budgeting. They are not the rate card of any company on this platform.
Insist the loss is quantified in kilolitres per day. At the City's upper tariff steps that number converts directly into a monthly rand figure, which is what gets a repair approved.

Frequently Asked Questions
How is a leak found on a site that never stops?
By narrowing before pinpointing. Night-line analysis measures what is drawn when nothing should be running, step testing isolates the zone, and correlation locates the break within it.
Do we have to shut down for this?
Not usually for the detection. Most of it is scheduled into an existing overnight window or a planned shutdown, because low demand gives cleaner readings as well as avoiding disruption.
What is the difference from industrial leak detection?
Very little. Factory work is the same discipline with production-specific systems added, particularly steam, condensate, cooling and wash-down circuits.
