The per capita availability of fesh water has dropped to 1,869 cubic metres in 2001 and is likely to further decline to 1,341 cubic metres by 2025 and to 1,140 cubic metres by 2050, CII said.
According to the World Water Development Report, India sat comfortably at the bottom with regard to water quality and willingness and ability to improve it.
The conference would aim at sensitising people and developing a broader political consensus on the issue.
Suggesting a holistic approach to meet the challenge, CII said an independent regulatory authority should be set up, greater stress should be laid on public-private partnership in the water sector, rationalising tariffs and targeting subsidies, implementing and promoting conservation measures and community involvement.
The conference would also discuss financial constraints of civic bodies supplying water, sewerage problems and lack of public resources
