Twelve water treatment services for Hong Kong buildings — treatment, cleaning, disinfection, testing and monitoring, delivered by our own specialists, technicians and engineers since 1982.
01We keep your cooling towers clean, efficient and under the EMSD Legionella limits — and give you the records to prove it.
02A deep clean and disinfection that clears sludge and biofilm, controls Legionella, and resets your tower to a safe baseline.
03An independent check of your cooling tower — water quality, records and condition — with a clear report you can act on, including the annual audit the EMSD FWCT Scheme requires.
Change only the href on that anchor:
04Chlorination of new or repaired drinking water pipework and tanks before they go into service — dosed to 50 mg/L, held 24 hours, flushed and laboratory-tested.
05Pre-commission cleaning that clears scale, debris and biofilm from new pipework — new plant and mall shop fit-outs alike.
06Treatment programmes for steam and hot water boilers that stop scale and corrosion before they cause damage or downtime.
07Live monitoring of your water system, online and around the clock — with automatic dosing and alarms, so problems are caught before they become notices.
08Water sampling and laboratory analysis — drinking water, pool water and Legionella — with formal reports you can file or forward.
09Risk assessment, sampling and treatment that keeps Legionella counts safely in the “undetected” range — and the records to prove it.
10Chlorine tablets and sodium hypochlorite, supplied locally in Hong Kong.
11Hardness scale dissolved off the fill in place — descaler recirculated for 4–6 hours, then neutralised and rinsed. A separate job from the routine clean.
12Tanks drained, cleaned, disinfected and refilled, with a laboratory test before the water goes back into use — routine, after repairs or after contamination.
Every job starts with a free site visit and a written quotation.
