This World Environment Day, Outlook looks at the water crisis that Delhi has begun grappling with as summer sets in. In Delhi's Lal Kuan, water has been a major concern despite residents regularly complaining to the Jal Board. The number of tankers is limited — when four are expected, only two arrive — leading to fights in the neighbourhood. When water becomes too scarce, residents have to arrange for private water tankers that cost around ₹1200–1300. A tanker serves a family for only 3–4 days, depending on the family size — sometimes even less.
