Construction is currently underway in Constantia Kloof to replace and upgrade water pipes. Residents have been plagued by water outages and frequent pipe bursts in the area.
Louis Pretorius, community liaison officer for the WPR project in Constantia Kloof said it had been a slow start for the project but the first pipes were set to be laid on Friday, 7 May. The contract duration is expected to be four months.
Site investigations were done by Johannesburg Water Engineering Services Unit, to assess the project site and ensure that the scope of work was adequately understood and measured. It comprises the replacement of existing 100mm diameter steel pipes with 110mm uPVC pipes, 75mm steel pipes with 110mm uPVC, and 110mm steel pipes with 110mm uPVC pipes by means of the conventional open-trench method, as well as the horizontal directional drilling (HDD) construction method on major road crossings.
Streets that are expected to be affected are Bamboes, Boomgom, Worsboom, Kroton and road crossings. The scope of the work includes:
• Replacing about 408m of 100mm diameter steel pipes with 110mm diameter high-impact mPVC Class 16
• Replacing about 235m of 75mm diameter steel pipes with 110mm diameter high-impact mPVC Class 16
• Replacing about 465m of 110mm diameter steel pipe with 110mm diameter high-impact mPVC Class 16
• Replacing about 202m of 110mm diameter AC pipe with 110mm diameter high-impact mPVC Class 16
• Replacing about 25m of 100mm diameter pipe with 110mm diameter HDPE pipe using horizontal directional drilling method
• Replacing about 25m of 150mm diameter pipe with 160mm diameter HDPE pipe using horizontal directional drilling method
• Locating, exposing and protecting existing services
• Doing three tie-ins to connect the new network to the existing network
• Reinstating surfaces to original condition
• Replacing 65 below-ground domestic water meters with above-ground meters
