The challenges of ecological sanitation in coastal south India - A case study of Kovalam town - South Chennai (Tamil Nadu) - A presentationPosted on 11 Aug, 2011 05:48 PM
This presentation by Sekhar Raghavan, Director, Rain Centre, Chennai, India highlights the experiences and the challenges faced by Rain Centre in introducing ecological sanitation in the coastal town of Kovalam near Chennai, Tamil Nadu, India along with Coastal and Rural development Trust (CRDT), a small non profit centre based in Kovalam .
The coastal town of Kovalam was selected as a case because of its peculiar situation with its location in a fast developing peri-urban area in proximity to Chennai city characterised by good groundwater situation, adequate land and housing facilities, but with a glaring and urgent need and demand for toilets.
The water position in Chennai has been satisfactory for several years now because of a couple of good monsoons, good supply from Andhra Pradesh and from the Veeranam Lake. The rainwater harvesting systems installed by many citizens have also helped in improving ground water levels. However, citizens should not presume that their water problems are solved for the following reasons;
Chennai’s water needs are mainly met by impounding the rainwater from the Araniar-Kortalayar rivers north of the city and the capacity of the reservoirs is woefully inadequate. It has been estimated that an entire year’s supply flows wastefully into the sea consequently. The quantum of supply from AP and the Veeranam Lake is uncertain.
The document informs that traditionally Indians worshipped both water and rain as “Jala” and “Varuna”. Even rivers were worshipped. Till 3000 B.C., RWH happened without human effort as rain got collected in rivers and natural depressions. Civilizations flourished on river banks all over the world Indus valley civilization in India.
