Jaipur in the Indian state of Rajasthan is having trouble getting enough water and has called in experts from Singapore and the US firm CH2M Hill to help it recycle and reuse.
Called the "pink city" because of the colour of many buildings, and home to some 4 million people, Jaipur has seen rapid population growth, like other Indian cities, as people migrate from the countryside.
Pollution, urban encroachment and climate change have put pressure on the availability of the city’sÂ traditional surface water supplies, said CH2M Hill, with water security expected to degrade further in the next decade.
To address the problem, Jaipur has turned to industry experts and to Singapore, which has tackled its own water scarcity issues through recycling and reuse programmes involving advanced treatment technologies, and public education.
So Jaipur has drafted in the Singapore Public Utilities Board (PUB) and Singapore Cooperation Enterprise to help, along with CH2M Hill, which has a lot of experience in water recycling projects, including for larger Indian cities such as Delhi and Bengaluru.
