Question

how people living in hilly area get water

Answer 1

People in hilly areas generally depend on rain only for their water. They also practice rain water harvesting techniques to get water. In hilly areas the routes to water sources are often long and difficult. People carry heavy loads across steep paths and ravines commonly resulting in serious injuries. They use rainwater harvesting to help combat the falling water levels. They can also use technologies to bring water directly from the source to people’s homes, helping them to avoid long and treacherous journeys.
