Ranhill SAJ Sdn Bhd developed a yearly pipe replacement project in order to reinforce their water supply infrastructure to continue providing water to local residents and businesses and also to supply future developments in the town. The new pipeline is to cope with the large number of new houses being built in and around the town and maintain supplies and demand to its networks. This work was to allow for extra capacity, greater network resilience in anticipation of the housing developments being planned and would involve laying approximate of 33km of new pipeline in the town to provide extra capacity to meet the water needs of the growing number.

This project consisted mainly of the replacement of old pipes by new ones that could keep and maintain a safe, reliable, and clean water supply to all residents making sure that the pipe's reliability and pressure maintained an acceptable level.

The installation take place in town of Kulai and Pontian which to be laid on the roadside in the residential area. This project needs to be completed within 18 months from its kickoff date (March 2023). Hence, this installation plan must be incorporated on minimizing the traffic disruption.

The existing pipeline materials were Asbestos Cement pipes. PVC-O pipes were introduced within the options due to the advantages that this kind of pipes imply and finally, this was the selected option due to the reasons.

• Lightweight, hence less equipment needed to lift and install. Speed of installation will be faster in comparing to the other types of pipes. They weigh less than the half of PVC and PE pipes
• Ease of jointing (no butt fusion welding).
• High hydraulic capacity and pressure with effective cost of project ownership cost (material & installation)
• 50 years of warranty
