Drainage Analysis

Inferences

• Abul fazal drain is taking sewer of the colony directly to the Yamuna. • Most of the Nalas are closed but some drains like Abul fazal, Tehkhand are partly open which causes frequent blockade. • Residents of Jasola Vihar are directly dumping their sewer into the Tehkhand Nala (which is suppose to bring treated water from Okhla WWTP) then dumping waste water into Agra canal. • According to the proposal by the Delhi Jal boards, settlements like Abul fazal, Shaheen bagh are proposed to flow to Jasola waste water pump station then forward to Okhla waste water treatment plant. • Jasola irrigation channel gets highly polluted passing through the village.
