Clean water and sanitation for India

I am a 6th grader, and I am trying to raise some money to help improve access to clean water and sanitation throughout India. The main problem people are facing is that 163 million people in India suffer from a lack of clean water and 210 million Indians lack access to improved sanitation. 21% of diseases are linked to unsafe water in India and nearly 70 percent of India's water is contaminated.
