Water Problem and DJB

Water shortage in delhi is known to DJB and political bosses and is there fore not a new phenomenon.
Solution may invole long term strategy and expenditure of crores of rupees.
But baffling is that tube wells functional in almost all residential societies and even services were handed over to MCD, were functional but were made in operative just a few years ago.
Such tubewells were boosting and to some extent mitigating water shortage.
Unfortunately, some decision at policy maker level has been taken without consideration of discomfort to citizen.
Could any body throw light as to how DJB COULD BE MADE TO REALISE THEIR FOLLY.
