New stormwater drainage system
FOR HERMANUS CBD
A new stormwater drainage system has been installed at South Africa’s whalewatching hotspot. A substantial increase in non-permeable paved surfaces and buildings over the decades, combined with an increase in the intensity of rainfall, meant that the CBD’s original ø300mm stormwater drainage system could no longer cope and the area’s High St and Main Rd had f looded on at least three occasions during the previous eight years. The new system comprises a combination of 450mm, 525mm, 750mm and 900mm (Above): Tertius Retief of Element Consulting Engineers inspects the outlet structure and the construction of gabions around the ø900mm pipe outlet above the entrance to the ø450mm exit pipe.
