Procedure for Water Service Installations


PUB adopts a simplified procedure for the design, installation and inspection of water service installations within the customer's premises.

The procedure requires the water service workers to notify PUB before commencement of water service works by submitting the site plans and schematic drawings of the water service installation. Once water service works are completed, they are required to submit a Certificate of Satisfactory Completion of Water Service Work certifying that the water service installation is completed in accordance with the Public Utilities (Water Supply) Regulations, Singapore Standard CP48 - Code of Practice for Water Services, all other relevant statutory requirements and other PUB requirements.

Water service workers, i.e. Professional Engineers (PEs) or the Licensed Plumbers (LPs), need not obtain PUB's approval for the detailed water reticulation system drawings and apply for an inspection before turn-on of the water supply.

Water service workers can submit their notifications, drawings and certificates electronically to PUB through the CORENET e-Submission System.
