The legal requirement — what PUB expects
Annual cleaning & certification is mandatory
Under PUB Singapore requirements, all MCSTs and building owners must have their potable water storage tanks cleaned, disinfected, inspected and certified at least once every 12 months by a PUB Licensed Plumber (LP), in line with SS 636 (Code of Practice for Water Services).
These tanks store PUB-supplied water intended for human consumption, and failing to complete the annual certification on time is an offence under the Public Utilities (Water Supply) Regulations. Waves Fluid Engineering carries out all tank cleaning works according to the latest PUB standards.

Isolation & draining
The tank is safely isolated from supply and drained, with minimal disruption to the building.
3
Internal cleaning & washing
Walls, base and fittings are thoroughly cleaned to remove sediment, moss and buildup.
4
Sterilization & disinfection
The tank is sterilized and disinfected using approved procedures to eliminate bacteria.
5
Water sampling & lab testing
Water samples are sent for chemical and bacteriological testing, with lab reports provided.
6
Certification & PUB submission
Our licensed plumber completes the certification and handles the PUB submission process.
