Maintenance manager at Suncoast Casino and Entertainment World John van Zyl and his team have embarked on a mission of making Suncoast an environmentally friendly building by implementing water-harvesting techniques.
A pilot project for the casino floor — which covers more than 7000m2 and uses six air handling units (AHU) to regulate the temperature — the water-harvesting technique used by John and his team has helped Suncoast to save about 1 209 600 litres of water per month.
“Each AHU will give us about 280 litres an hour at an outside air temperature of 25°C with 33% humidity, which adds up to 6 720 litres per day per unit. As the humidity increases, so will the hourly litre rate increase, or alternatively, as the humidity decreases the rate will decrease,” Van Zyl explains.
The water is passed through primary and secondary strainers before being collected in tanks, which is then treated with a chlorine system to ensure water quality. The water is then pumped to the main domestic water tanks, which are used by all tenants within the casino.
“I believe it is every person’s responsibility to play their part in using water wisely and also to incorporate systems and measures for recycling water and trash. If we do not do anything about it, who will?”
The water has been tested by an independent company, Ecosafe, who does quarterly Legionella (bacteria that flourish in air conditioning and central heating systems) testing, and has found the water to be safe for human consumption. Ecosafe also carries out a monthly test on the water to ensure it is safe for consumption at all times.
“Water is a very precious commodity and I believe that we as South Africans are finally seeing that, thanks to the drought that has wrought havoc in KwaZulu-Natal and other parts of South Africa,” says Suncoast executive director Mike Dowsley.
“I believe it is every person’s responsibility to play their part in using water wisely and also to incorporate systems and measures for recycling water and trash. If we do not do anything about it, who will?” Dowsley asks.
Van Zyl and his team also harvest about 4 500 litres per month from the six heating, ventilation and air-conditioning HVAC cooling towers. This water is collected in a water tank, from where it is pumped to flush the toilets and urinals in the public toilets of the conference centre.
Influenced by the Art Deco style of Miami’s South Beach, the hotel is located on Durban’s Golden Mile and is within walking distance of the Moses Mabhida Stadium. It has been the recipient of several awards.
