Water seepage on private premises is primarily a matter of building management and maintenance for property owners and occupants.

If water seepage problems involve the water supply system, owners may consider appointing a licensed plumber under the Waterworks Regulations (Cap. 102A) for checking the system and carrying out the necessary repair works. In this respect, the licensed plumber directory is available on the following webpage of the Water Supplies Department for reference.

Please note that the Water Supplies Department will not intervene in a private dispute arising from a mild water seepage nuisance where there is no evidence of waste of water.
