About the course

This short note is a sequel to my earlier article which analysed the functioning and performance of my Roof-top Rainwater System using Rainy filter. While the earlier article narrated my initial observations on using the Rainy FL-100 filt

Green pastures and meadows, tall trees, lakes, wells and the river…those are my memories of Delhi. It wasn’t too long ago that one woke up early to the sounds of lawns being watered, children running off to school and people walking in the parks. A flurry of activity but quite different from what it is today.

Uday Shankar from water.org welcomed the audience and introduced the issue of access to safe water and sanitation. Gary White, water.org, set the tone of the seminar by explaining his organisation’s vision of ‘getting safe water’ for everyone.

This article published in the Encyclopedia of Life Support Systems includes a collation of traditional household water purification methods practised by rural communities in developing countries.

This three day national seminar was jointly organised by the Kerala State Council for Science, Technology and Environment (KSCSTE), Thiruvananthapuram, and the C Achutha Menon Foundation (AMF), Thiruvananthapuram, Kerala and included presentations and discussions on a range of water related themes such as water scarcity, water conservation, commercialisation of water, water conflicts and water management.

The seminar aimed at creating awareness and triggering a dialogue among scientists, academicians, researchers, activists, as well as lay people on the emerging challenges related to water resources, water quality and water conservation in the state of Kerala. The seminar was inaugurated by Shri V M Sudheeran, Ex MP and former speaker, while Dr Rajasekaran Pillai, Executive Vice President KSCSTE, delivered the keynote address with the felicitation by Shri M P Achuthan, MP.

The seminar included discussions under five different themes related to water issues that included water scarcity, water conservation, commercialisation of water, water as an new area for conflicts and water management.

A close examination of these two issues shows that the water and sewage challenge is already grave and could get worse. With this as the backdrop, Centre for Science and Environment (CSE), a public interest research and advocacy organisation based in New Delhi, organised a two day conference called the Anil Agarwal Dialogue on “Excreta does matter”. The conference took place at the Jacaranda Hall, India Habitat Centre, Lodhi Road, New Delhi on 4 and 5 March 2013.

The dialogue aimed at furthering the agenda of CSE’s seventh State of India’s Environment report titled Excreta Matters. This report is a comprehensive survey of the situation of water and wastewater management in 71 Indian cities. The study found that most cities lack a basic policy direction on how best to tackle issues of demand, supply and treatment of water, and of management of sewage. 

The Dialogue being the first of its kind brought together a wide range of professionals, activists, practitioners, policy makers, academicians, researchers and administrators from the water sector. The event was aimed at drawing attention on the critical issues of how cities will get affordable and sustainable water and waste systems that can supply to all and take back and treat the sewage of all.
