Borehole drilling

Borehole drilling in Hong Kong

Updated 5 November 2026

We could not confirm a current HK$ price range for borehole drilling in Hong Kong from published sources, so this page does not quote one. In practice each borehole is priced per job, once the depth, the ground and the access to the site are known. The fastest way to a real figure is a request on BlaBlaPrice, where sellers reply in the chat with their own offer.

• type of work and its purpose (water supply, ground testing or another use)
• location: Central, Kowloon, Sha Tin, Tsuen Wan or Tuen Mun
• depth of the hole and the ground it passes through
• casing pipe and any extra features
• rig access to the site
• deadline and budget

Local rules and what to check

Hong Kong has a recommended standard for site investigation, called Geoguide 2, which sets out good practice for ground investigation work here. Ask any seller whether they work to it and how they record the exact position of each hole. If the drilling produces water that will be discharged, check whether a licence is needed under the Water Pollution Control Ordinance, because the rule says trade discharge into a water control zone should be covered by a licence.

Season and timing

November falls just before the winter months, which run from December to February in this northern-hemisphere climate, and summer runs from June to August. Starting now gives sellers time to plan the site visit and the drilling before December. If the work is needed sooner, say so in the request, since the deadline is one of the details sellers need.

How it is bought in Hong Kong

State the district from the list above and the exact site address, so the seller can judge rig access. Depth is quoted in metres, and the casing pipe is best described by its diameter in millimetres. Ask whether the offer includes the site visit, the rig transport and the removal of drilling material.

What to write in your request

Start with the purpose: water supply, ground testing or another use. Then give the district, the planned depth in metres, what you know about the ground, and whether a rig can reach the spot. Add the casing pipe and any extra features you want, your deadline and your budget. The more of these details you give, the more precise the offers will be.

On BlaBlaPrice you describe the job in your own words in a chat, and you can add a photo. The service is free for buyers.
