 In recent years however, due to heavy and consistent monsoon rains and the implementation of rainwater harvesting (RWH) techniques by Chennai Metrowater at their Anna Nagar Rain Centre, water shortages have been reduced significantly, and this has led Chennai to be a model of RWH technology for other cities.Moreover, newer projects like the Telugu Ganga canal project that brings water from water-surplus rivers like the Krishna river in Andhra Pradesh have eased water supply shortages.The city is also constructing sea water desalination plants to further ease water supply shortages.
