New life for sewer pipes at Tygerberg Hospital through pipe relining.

Updated: Jun 13, 2023

The Tygerberg Hospital has commenced the repair and upgrade of its underground sewer network. The Western Cape Department of Public Works, in collaboration with the City of Cape Town, issued a tender for the relining of the pipes in mid-2022. Leakfind, the chosen contractor, was awarded the project in October 2022.

The scope of the project encompasses multiple tasks, including relining the existing pipes, replacing damaged sections and high pressure cleaning of all the lines and CCTV inspections.To minimise disruptions, the work is being conducted in phases, targeting different sections of the hospital's infrastructure at various times.

The relining process involves the utilisation of a specialised epoxy and liner system to create a new pipe within the existing one. This method eliminates the need to excavate and replace the old pipe, which can both be expensive and disruptive.

Upon completion, the project is expected to yield several benefits. Throughout the project the utmost care is being taken to ensure minimal disruption to hospital operations and to prioritise the safety and comfort of patients and staff.

The initiative at Tygerberg Hospital forms part of a broader infrastructure upgrade agenda undertaken by the Western Cape government. The aim is to enhance the quality of essential services within the region.

The benefits of this form of pipe rehabilitation also include that tree roots cannot penetrate the pipe after it has been relined, there are no more joints in the newly lined pipe that could start leaking again in future and there is a significant gain in energy due to the water flow in the piping system now moving with less friction.

In summary, the Tygerberg Hospital pipe relining project is a significant infrastructure upgrade that will not only contribute to the hospital's smooth operation but also enhance water management in the area.
