Rainwater harvesting (RWH) was explored as a possible method to alleviate seasonal water scarcity in Himachal Pradesh. To investigate the feasibility of RWH, local residents were surveyed about their current water infrastructure and their perceptions of RWH. Based on analyzed data, models of RWH systems were designed for potential implementation on the IIT campus, Mandi town, and nearby villages. It was determined that RWH systems would be bene icial, but costs, lack of infrastructure, and misconceptions about RWH have impeded implementation.

Project Outcomes

Our first recommendation stems from cost concerns that we found while conducting our interviews We solution believe that the IPH, or the Himachal Pradesh government, should offer a subsidy to offset the initial cost of rainwater harvesting systems. The subsidy will give the residents an opportunity to acquire a supplementary water supply, increasing the amount of water on hand while decreasing demand on the IPH public water distribution system. Instituting RWH systems will provide a secondary source of water that does not rely on piped water infrastructure or draw water from nearby rivers and groundwater.
Our second recommendation is to educate the people of Mandi about rainwater harvesting and its bene its. Our third recommendation includes short and longā€term plans for the IIT in regards to rainwater harvesting.
