PROJECT 45 plumbing system was up-and-running in the minimum time,” says Tsabedze. “One of the principle reasons for choosing to work with Geberit was the local backup. The system is relatively easy to maintain and, with aid from Geberit themselves, keeping it up and running over the years should be a simple matter,” explains Tsabedze. In the bathrooms, Uhuru installed Geberit cisterns for all toilets. Once again, the major concerns were reliability and the ease of future maintenance, which, according to Tsabedze, was pretty much guaranteed due to the proven history of the Geberit system, but the 4.5ℓ flush was also considered attractive. The building consists of 10 courtrooms, including one civil court, two family courts, and one child, domestic violence, and peace order court. “If the rest of the system wasn’t already Geberit, we probably would have gone with their cisterns due to the 25-year guaranteed spare parts availability,” says Tsabedze. The domestic water system ends in the bathrooms through the Geberit Bathroom Collection, which is described as being elegant and functional with a focus on how easy they are to clean and, once again, maintain. The interesting part of the domestic water system is the way the water is heated. The hot water system uses two ring mains via circulation pumps from the two different hot water tanks and electrical element backups. These two hot water tanks are heated by the VRF heat recovery system, with electrical elements as a backup in the event of HVAC failure or downtime. This system ensures a significant energy saving, which in turn leads to lower running costs. Due to the desire to save space, Uhuru went with the Geberit Pluvia roof drainage system, which requires fewer downpipes due to its high-volume capabilities, and maximises the use of space inside the building due to its ability to lay pipes horizontally without slopes. The result is an efficient and extremely resilient system that pleased the final client and met all the SABS and Department of Works requirements. PA Uhuru Wetu Consulting were the wet engineers on the project. The system uses Grundfos pumps to move water into Geberit Mapress Stainless Steel pipes.
