Water treatment for hotels
Chilled water, cooling towers, hot water and pools — under one contract, with the documentation your group audit asks for.
A hotel is several water systems at once, and each carries a different risk. Gotech covers all of them under one contract: cooling towers and chilled water for the plant, hot water services and pools for the guests. Several of our hotel contracts have run continuously since 2015.

The systems we look after
What is actually at risk
A hotel's exposure is not only regulatory — it is reputational. Legionella is associated with hot water services and spa pools as well as cooling towers, and guests are a transient population who take any illness home with them. Meanwhile brand standards and group audits demand documentation that a local contractor can actually produce.
Why Gotech fits
- One contractor across cooling, hot water and pool systems — not three
- Reports formatted for group compliance files and brand audits
- Work scheduled around occupancy, not around us
- Pool water testing and chemical supply from the same team
- Several hotel contracts running continuously since 2015
Client names, including hospitals and government sites, are kept private. Full reference lists are shared with quotations on request.
Frequently asked questions
Can one contractor handle a hotel's cooling towers, hot water and pools in Hong Kong?
Yes. Gotech covers a hotel's plant and guest systems under one contract: cooling towers and chilled water, hot water services, swimming pools and spa, and kitchen boilers. Pool water testing and chemical supply come from the same team, and several of our hotel contracts have run continuously since 2015.
Why does a hotel need Legionella control beyond its cooling towers?
Because Legionella is associated with hot water services and spa pools as well as cooling towers, and guests are a transient population who take any illness home with them. A hotel's exposure is reputational as well as regulatory, so the hot water and leisure systems need the same treatment discipline as the plant — with documentation that brand standards and group audits will accept.
Will water treatment work disturb hotel guests?
It is scheduled not to. We plan the work around occupancy, not around us, and every visit ends with a dated report formatted for group compliance files and brand audits. Each job starts with a free site visit and a written quotation, and the work follows the EMSD Code of Practice.
