Potential Water Balance using Rainwater: An Analysis of Delhi, Megacity in India

Abstract

Delhi is one of the most water stressed cities in the world. This study aimed to explore the potential of Rainwater Harvesting (RWH) as an alternative source of the water supply for Delhi. Mass curve method has been used to understand the feasibility of RWH, indicating that an average roof of 60 m2 in Delhi will collect 3,64,800 L of water in a year for an average family size of five people. The present study assumed that financial constraints, erratic rainfall, unclear legal guidelines, poor public perception, and a lack of commitment from the politicians are possible challenges.

Research progress on compounding agent and mechanical test method of fluororubber

“…They are reinforcing agents, 9 softening plasticizers, 10 anti‐aging agents, 11 accelerators, 12 vulcanizing agents, 13 auxiliaries, 14 and fillers 15 . However, apart from the performance of FKM, fluororubber products have the same strict requirements on environment, hygiene and raw material sources 16–18 . At present, countries around the world advocate sustainable development, which is a “green” development concept, that is, while the economic benefits are steadily increasing, it is also necessary to ensure environmental optimization and reduce pollution 19 .…”
