Water treatment for housing estates & clubhouse pools
Fresh water tanks, clubhouse pools and cooling systems — for owners' committees and managing agents who have to justify every dollar.
Fresh water tanks, clubhouse pools and cooling systems — for owners' committees and managing agents who have to justify every dollar.
Estates are a different buyer: the decision is made by an owners' committee or managing agent who must justify the spend to residents. The systems are usually fresh water tanks, a clubhouse pool, and cooling plant. The work has to be right, documented, and defensible at a meeting.

Residents are not a transient population — they are the people who will attend the meeting. Drinking water tanks and a clubhouse pool are both visible, both emotive, and both need a clear written result rather than reassurance.
The estate's cooling towers answer to the EMSD Code of Practice. The clubhouse pool answers to a different authority entirely: under the Swimming Pools Regulation (Cap. 132CA), a pool that the public can access, or that is operated by a club, institution, association or other organisation, must be licensed by the Director of Food and Environmental Hygiene — and the only exemption in FEHD's published licensing guide is a pool serving not more than 20 residential units with no public access. In practice, almost every estate clubhouse pool operates under an FEHD licence.
That licence carries daily working obligations, not just a certificate for the clubhouse wall. FEHD's published licence conditions include holding pool pH between 7.0 and 7.8 and free residual chlorine at not less than 1 ppm at all times bathers are in the water, testing chlorine and pH every day, keeping a register of the results, and displaying the day's readings on a notice board at the pool entrance. We set out the full picture — who needs the licence, the water quality standard behind it, and the records worth keeping on file — in swimming pool licences in Hong Kong: what the licence requires.
This is where monthly testing, chemical supply and plain-language reports stop being three separate purchases: scheduled testing gives the committee independent numbers to file alongside the daily register, chemical supply keeps chlorine and pH correction stocked to the levels the licence names, and a report residents can read is the same document a manager can show an FEHD inspector.
Client names, including hospitals and government sites, are kept private. Full reference lists are shared with quotations on request.

Gotech cleans and disinfects estate fresh water tanks, with laboratory testing to confirm the result. Quotations are written so they can be tabled at a committee meeting, reports are in plain language residents can read, and pool chemicals — chlorine tablets and sodium hypochlorite — are delivered locally by the same supplier.
