The rapid increase in global population and the acceleration of urbanisation are leading to greater water needs, water scarcity and a rise in the reuse of wastewater, either directly or indirectly.
Binnies in Singapore first identified the potential of using sewage as a water source in its 1977 study “Special Water Sources” for the water authority there. High-grade reclaimed water with quality good enough for potable use, which is known as NEWater, was introduced in 2003 when the costs of employing the rigorous three-step purification process involving microfiltration, reverse osmosis and UV disinfection were no longer prohibitive. Binnies has since largely contributed to 60% of the total NEWater production and assisted in turning Singapore into a global hydrohub for pioneering new water technologies and increasing resilience to climate change.
In Hong Kong, Binnies is helping the Water Supplies Department to design and construct the first centralised grey water recycling system. This comprises a grey water treatment plant with associated pumping system, a service reservoir, pipes for grey water collection and distribution of the treated grey water. Along with harvested rainwater, the grey water will be treated and reused for non-potable urban applications such as toilet flushing and street washing. We are also helping to expand the city’s water supply through the recycling of treated sewage effluent for a number of sewage treatment works projects.
In the UK we have designed grey water plants for many high-profile projects such as Heathrow Terminal 5 and the London Olympics.
