This summer, Chennai Metrowater’s well fields in Tiruvallur district will be rejuvenated after a gap of nearly a decade to tackle water shortage in the city.

The fast-depleting resources in the reservoirs, the major suppliers of drinking water to the city, have set the focus on well fields in Poondi, Tamaraipakkam and floodplains near Kosasthalaiyar river. Besides rejuvenating the 20 borewells in these well fields, the water agency plans to sink 16 more borewells to augment water supply.
