After 18 months, the long-awaited sewerage pipe replacement works has finally been completed on 10 July 2025 under Suruhanjaya Perkhidmatan Air Negara’s Sewerage Capital Contribution Fund.
This project took longer than the original 12-month timeline. The delay was largely due to the need to control soil movement during construction. The contractors had to move slower than originally intended, as extra care was required to secure the structural integrity of surrounding buildings as they moved along the project site. Whilst this extended the duration of the works, it ensured the long-term safety of the area.
In January 2025, SPAN approved a budget allocation of RM2.74 million for the project to replace the sewerage pipes located at Jalan SS15/4 and Jalan SS15/8 in Subang Jaya, Selangor Darul Ehsan. The project was initiated to replace sewerage pipes that were over 30 years old in the SS15 commercial area, which had been prone to frequent damage, resulting in blockages and backflow into premises. These have caused frequent disruptions to both the public and business proprietors operating in the vicinity.
The project was initiated following a request raised by myself to SPAN and Indah Water Konsortium (IWK), which was followed by a series of discussions. This project has benefitted approximately 40,000 students, workers, and residents in the SS15 commercial hub.
The length of the main sewer line installed is 400 metres, using vitrified clay pipes with a diameter of 225mm. The connecting pipes for all 46 existing shop lots measured approximately 150 metres, with a diameter of 150mm. The material is also vitrified clay pipes. In addition, IWK has also upgraded the drainage system in the area from 300mm to 450mm and 600mm U-Drains.
We are aware that some property owners had made unauthorised connections from kitchens as well as rainwater downpipes directly into the inspection chambers. The oil from kitchens is one of the main cause of blockages in the sewerage pipes, whilst the rainwater channelled often results in overflow as the capacity of sewerage pipes cannot cater to rainfall. This matter has been discussed with the Subang Jaya City Council (MBSJ), which will conduct inspection and issue notices to the relevant premises to redirect those connections.
In closing, I extend here my deepest gratitude to the former Chairperson of the SPAN, Charles Santiago and everyone in the agencies, IWK, MBSJ, the patience of shop owners and all stakeholders who contributed to the successful completion of this project, recognising their dedication, expertise, and cooperation in addressing the long-standing issues faced by the Subang Jaya community.
