Water management is a challenge no doubt, but it is not something which cannot be met. Better water harvesting system, interlinking of rivers may be an option at the country level. Citizens have to contribute by change of attitude regarding wastage of water. Waste water management by newer and improved technologies is required all over. Unfortunately targeted initiatives from government is somewhat lacking.
For example food waste is thrown all over. Collection of MSW by municipalities all over India is not more than 30 %, and that too is dumped in land dumps (not secured landfills as there is hardly any). Eventually food waste is washed in drains thus choking the drains and in the long run causing eutrophication or drying up of water bodies. Effective monitoring is required which grossly lacking in our system.
Public participation can come only when the intention of the civic bodies etc are well known to be strict. There is also a need to educate the masses through awareness programmes (provided for in the MSW 2000 but not resorted to). NGOs should be encouraged to programme public education.
