A Hong Kong water treatment company since 1982

Gotech Chemical Ltd was founded in 1982, providing water treatment and maintenance services to clients in Hong Kong. Over more than 40 years we have grown from supplying chemicals and cleaning detergents into a full water treatment and engineering specialist.

Our clients include hospitals, hotels, electronics factories, commercial and residential buildings. We are a full-service company built to help clients meet the requirements set by the Hong Kong government.

Our people

Gotech has more than 20 staff — water treatment technical specialists, certified trained technicians and engineers. Our teams complete the required safety training and come to site in proper uniform with identification, ready to work.

Our track record

• 500+ clients as of 2026 — some are property management companies with many buildings under their care
• 11 hospitals on Gotech real-time monitoring — live pH, chlorine and more
• Hotels, malls and office towers on long-term maintenance contracts, some running since 2015
• Many government facilities — sports centres, municipal buildings and offices
• Water-treatment works delivered for the EMSD's E&M Services Department at Hong Kong public hospitals — and the EMSD is the department that regulates cooling tower water quality
• On the EMSD's approved vendor list — vendor number supplied with tender documents on request

Safety

Site and worker safety is our top priority. Work complies with the ordinances and specifications of the Hong Kong SAR government, we follow a no-smoking policy on site, and waste from the water treatment programme is removed as directed by the estates management office.
