A low-maintenance, gravity-system aqueduct provides low-cost security of the Durban water supply. The vulnerability of the Nagle Aqueduct, which joins Nagle Dam and Durban Heights water treatment plant via a series of tunnels and siphons, was illustrated during the 1987 floods. In order to increase the security of the water supply and to utilise Inanda Dam water, Umgeni Water decided to implement the construction of Phase 2 of the Inanda Wiggins Aqueduct. The project was one of the nominations for last year's Durban Branch Award for Excellence in Civil Engineering.
