Drinking water tanks accumulate sediment, biofilm and whatever the roof and the atmosphere deliver. Gotech drains, cleans and disinfects the tank and connected pipework, flushes the system, then tests the water in the laboratory to confirm it is safe before it goes back into use. Needed for new or repaired systems, after any suspected contamination, and as routine building maintenance.
A fresh water tank is a reservoir of drinking water that usually sits in the dark, unwatched, for years. Sediment settles. Biofilm develops on the walls. If the cover or screening is imperfect, dust, insects and worse get in. None of this is visible from the tap until it is very obvious indeed.
This is a different risk profile from a cooling tower. Nobody inhales aerosol from a water tank — they drink from it. That makes the acceptance criteria different, and it makes laboratory confirmation non-negotiable rather than nice to have.
This service is needed for newly installed or repaired plumbing, after any suspected contamination, and as periodic maintenance. The trigger people forget is the repair: opening a main and closing it again introduces exactly the contamination the system was designed to exclude.
A drinking water problem is not a slow financial bleed — it is an acute event. It is visible, it is emotive, and in a housing estate or hotel it arrives with an audience. The remediation is not the expensive part; the trust is. Routine cleaning with a documented lab result is a small, predictable cost that keeps the question from ever being asked.
It depends on the tank, its condition and its environment, and periodic cleaning is normal building maintenance. It should also be done whenever the system is new, has been repaired or opened, or where contamination is suspected — for example after a typhoon or flooding — regardless of when the last clean was.
Yes, and this is the point of the exercise. Cleaning without confirmation is an assertion; a laboratory result is evidence. We test and give you the report. See laboratory testing.
Draining and cleaning, disinfecting the tank and connected pipework, flushing the system through, inspecting the covers, screens, overflow and access, sampling for laboratory testing, and a written report with the lab results. The water is confirmed safe before it goes back into use, not after.
Yes. This service is needed for newly installed or repaired plumbing, after any suspected contamination, and as periodic maintenance. Opening a main and closing it again introduces exactly the contamination the system was designed to exclude, so a new or repaired system should be drained, cleaned, disinfected, flushed and laboratory-tested before the water goes back into use.
Tell us the building and the tank and we will quote the work, including the lab test.
