Role of Drain Number 8
About 300 cusec of water is supplied to Delhi via Drain Number (DN) 8. The drain branches off from Western Yamuna Canal (WYC) near Garhi Bindroli village in Sonipat. The total length of the drain is about 25 km. It carries Delhi’s share of water and discharges it into River Yamuna at Palla, where the river enters Delhi territory.
The water then flows 21 km downstream up to Wazirabad barrage where it is treated at Wazirabad Treatment Plant (WTP). This plant also supplies water to New Delhi Municipal Council (NDMC) areas which includes President House, Parliament areas among other prominent VIP residential units.
