The Water, Sanitation, and Hygiene (WASH) sector play a pivotal role in public health, environmental sustainability, and socio-economic development. Despite its importance, India, like many countries, faces significant challenges in achieving Sustainable Development Goals (SDGs) related to WASH. The Wash Finance team at ISC is dedicated to analysing the current state of WASH financing, identifying the types of financing required, and addressing challenges stemming from insufficient funding. Our goal is to propose innovative financing instruments to tackle these issues effectively.
