NELSON MANDELA BAY STORMWATER MASTER PLAN

The Stormwater Master Plan (SWMP) JG Afrika did for Nelson Mandela Bay Municipality, Port Elizabeth, identified a number of key stormwater management issues and we were appointed to design various stormwater systems in areas prone to flooding.

The system at Allister Miller Drive comprises a 340 m concrete-lined open-canal system, discharging through splitter boxes over rock fill into an open area.

The runoff from Walmer South drains into the ACSA system and is then conveyed through the airport to discharge into the Allister Miller Canal.

At the Walmer Country Golf Club catchment, seven detention ponds attenuate and direct major stormwater runoff from the catchment away from Victoria Drive.
