The Delhi Jal Board's endless pleas to ask residents to stop using online booster pumps have actually yielded results in Vasant Vihar. In a tie-up with the Board, the Vasant Vihar Residents Welfare Association on May 22 agreed to remove online boosters on one street. Vasant Vihar RWA president Gautam Vohra said there was a time when half the streets had no water while the houses opposite were blessed with overflowing tanks. But not today.
