Hong Kong has many operators in the drainage and septic tank cleaning industry, with uneven quality and service scope. Quite a few leave only a phone contact, with no website and no reviews, making it hard for customers to judge in advance whether they are reliable. The following 6 points can help you choose the right drainage company.
1. Do they hold a Drainage Services Department registration number
Companies that handle residential liquid waste (septic tanks, grease traps) are legally required to register with the Drainage Services Department (DSD) and obtain a registration number. The list is published on the DSD's official website, so you can verify it directly.
2. Do they hold the relevant Environmental Protection Department licence
For work involving the collection and transport of chemical waste (for example waste oil from grease traps), a company must hold the relevant licence issued by the Environmental Protection Department, to ensure the waste is properly handled rather than dumped carelessly.
3. Is the quote transparent
A reliable service company can, at the phone or WhatsApp enquiry stage, already provide a fairly clear price range based on the on-site information you give (capacity, distance, location), rather than "we'll tell you once we arrive".
4. Does the service scope match your needs
Some companies only do a single type of job (for example only drain clearing). If your needs involve multiple services (for example septic tank cleaning, grease trap cleaning and CCTV pipe survey all at once), choosing a company that can handle everything in one stop reduces the time cost of coordinating different contractors.
5. Can they handle emergency call-outs
Drain blockages and septic tank overflows are often sudden situations. A service company's response speed, area coverage and fleet dispatch capability directly affect how quickly the problem can be solved.
6. Customer reviews and past track record
Pay attention to the company's reviews on Google and social platforms, or ask for past service cases (for example maintenance contract experience with similar restaurants or housing estates) as a reference for judging reliability.
