Century City is in a very fortunate position in that we utilise treated effluent water pumped from the Potsdam Waste Water Treatment Works for all its irrigation and therefore, the City of Cape Town’s Level 3 water restrictions are not applicable to the CCPOA and its members, who are connected to the Century City irrigation system.

Even though recycled water is utilised, our automated irrigation system operates mostly in the evenings, with maintenance taking placing during the day when our staff are at work. This assists by reducing the volume of water lost due to evaporation during the day time.

Given that we have a 250ha area, with over 100 000 sprinklers throughout the precinct, we unfortunately cannot time all the sprinklers to go on at once, as there would be no water pressure anywhere in Century City. So the sprinklers you do see on during the day, are the absolute bare minimum, and assist us in alternating the draw down in terms of water pressure.

Furthermore, as our 100 000 plus sprinklers are all on a timed system, it is not possible for us to reset this in accordance with the weather on that particular day.

Alan Liebenberg, Century City’s environmental manager, explains that Century City has its own pumpstation at Potsdam.
“The recycled water is pumped along our 7km pipeline – which was paid for by the developer - to a large holding reservoir (one million litres) under Intaka Island at Century City. From there it is pumped along an irrigation ring main with all the different properties within Century City able to draw off that main for their irrigation.

“Likewise the CCPOA draws off the main to irrigate all common areas.”
Liebenberg says the fact that Century City is using this recycled waste water doubly benefits the environment as it prevents this treated effluent water having to be fed into the Diep River and Milnerton Lagoon.
