The Delhi Jal Board has announced water shortages in East, Northeast, and South Delhi until November 1, primarily due to high ammonia levels in the Yamuna River. With the Upper Ganga Canal closed for maintenance, the Bhagirathi and Sonia Vihar Water Treatment Plants are struggling to meet demand, leading to a 30% reduction in water production. Residents, particularly in Saket, are protesting for immediate restoration of supply as Diwali approaches.
