Water and Sanitation

Water Conservation and
Clean Drinking Water

Integrating Rural Sanitation
with Rainwater Harvesting

Our aim is to align our projects and programmes in Water and Sanitation with the overall goals of the National Missions in India - Jal Shakti Abhiyan for Water Conservation and Water Security and the Swachh Bharat Abhiyan.

We have worked with the Centre for Product Design and Manufacturing and the Centre for Sustainable Technologies at the Indian Institute of Science (IISc.) to promote conservation of water and water resources and for clean drinking water-related issues such as portable UV water bottle developed at IISc.

Our work in scientific research, education and skill development aims to promote water conservation and improved sanitation and hygiene practices. We work with premier scientific research institutions, scientists, engineers, young researchers, students, teachers, local community members and self-help groups to promote sanitation and hygiene.

Rainwater Harvesting Integrated Rural Sanitation

The Centre for Sustainable Technologies (CST), Indian Institute of Science and Earthwatch Institute India promote the rainwater harvesting integrated rural sanitation initiative. We promote scientifically designed sanitation units to adopt sustainable sanitation practices. An integrated approach to harvest the rainwater and linking it to the use for sanitation can alleviate the water shortage.

Rainwater Harvesting

It is a simple, environmentally sound and economical means of storing and recharging rainwater. Construction of rainwater harvesting structures in open areas, office buildings and households is an environmentally sustainable solution. It improves the quality and quantity of water and maintains an environmentally sustainable water supply for domestic use. We have worked with Professor M.V.S.S. Giridhar to promote a successful rainwater harvesting programme at Hyderabad that involves the construction of demonstrative artificial rainwater recharge structures with a capacity to harvest surplus rainwater.

WASH - Water, Sanitation & Hygiene

We have developed resource material for WASH education in schools. The programme aims to enhance understanding and knowledge of water, sanitation and hygiene and the interconnectedness between different elements of WASH through experiential learning activities. It will increase awareness on safe water, sanitation and hygiene practices for human health and well being. The programme will encourage local solutions with the efforts of the local community members for clean water, sanitation and hygiene.

"The Centre for Sustainable Technologies (CST) has done pioneering work in the field of sanitation in rural areas. We are delighted to work with Earthwatch Institute India to promote these sanitation technologies at the grassroots and also develop skill development initiatives to train community members. The Rain Water Harvesting integrated Rural Sanitation Programme is one such initiative that uses dedicated rainwater supply for sanitation, powered by the solar photovoltaic panels and using low-carbon locally available building material. Looking forward to our continued association with Earthwatch Institute India, who are pioneering innovations in the field of water, sanitation, and hygiene with their niche in citizen science."
