The best thing about solar energy is that it has the ability to address the most basic requirements of leading a healthy life. When we talk about the most basic requirements, “water” tops the list. So here is our next CSR idea – Solar Drinking Water Solution.

Why should you consider Solar Drinking Water Solution projectas your next CSR initiative?

  1. India’s water sources are prone to contamination. According to statistics, almost 77 million people across India lack access to safe drinking water.
  2. India ranked 120th in a survey of 123 nations on safe water index by UNDP. This is because people in both urban and rural areas, mostly children, are largely affected by water-borne diseases.
  3. According to World Bank reports, 21% of communicable diseases in India are due to unsafe water.
  4. Death toll due to diarrhea is 1600 per day.

The data on water and the related challenges will be clear with these visual data.

The IWT 2.0 measures water quality with an Indian-government standard called Bureau of Indian Standards (BIS) limits. Surface and groundwater are both below par in many areas. (http://www.wri.org/blog/2015/02/3-maps-explain-india’s-growing-water-risks)

Solar Drinking Water Solution

This project deals with an integrated community-based intervention on water issues in both urban and rural areas. A solar-powered pump pumps raw water from the nearby lake or ground water into a storage tank. This water is then fed into a filtration unit, which does not require power to operate. It relies on the pressure with which raw water flows through it for filtration. Raw water flows through the unit, and the filtered water is collected in a collection tank. The tank is connected to community taps where people can collect pure drinking water. The plant runs entirely on green energy without the support of grid electricity.

This project will have widespread impact. We have listed few of the foreseen benefits –

  1. The filtration unit is very easy to clean and maintain. Once the project is installed and handed over to the community, it is easy for them to manage it. Unlike conventional filters that require energy, this one uses a technology that makes it easy to operate and maintain. Turning 3 knobs is all it takes to clean the filter.
  2. In villages in which we have installed these systems, there has been a decrease in incidences of diseases, especially water-borne diseases, skin diseases, and infections, thereby improving the personal hygiene and per capita income of the community.
  3. The children in these communities are healthier, enabling them to attend school regularly.
  4. The women in the community do not have to travel far to collect potable water, hence are able to save time, which they can then apply on non-domestic work.
  5. This project is based on a low carbon initiative. It reduces emission footprints and promotes the use of renewable energy through community-based intervention.

We have already implemented similar projects, which are benefiting the communities across the country. Let’s see the viability of the project –

A long-term solution – Apart from the initial investment on this project, no further costs are incurred, as the maintenance costs are negligible, making it a long-term solution to many problems in the community.

Easy maintenance – The filtration unit requires cleaning and servicing of the unit every 14-30 days to ensure it is in continuous operation. This can be taught to anyone from the beneficiary community, and is done by turning a few knobs on the unit.

Self- sustainable – The project is a self-sustainable one, which is handed over to the villagers to manage. Once we help them divide the responsibilities amongst themselves to ensure proper functioning of the system, within two months we exit the village.

Abundant Supply – The filtration unit delivers up to 10,000 litres of clean water a day depending upon the water condition. The units are designed for a life of a minimum of 5 years, with an expected service life of up to 10 years.

Valid for all conditions – This filter is capable of filtering muddy water, ground water etc., and output water has a ppm level that is permissible as per WHO standards.
