Dilli's ills - 2. Water is a precious 'fossil fuel' too!

Ha! The Delhi Government has approved the proposal to provide 20,000 litres of water free of cost to every household per month. Sewer charges were also withdrawn, to mark the 100 day milestone.
Delhi needs nearly over 5000 million litres per day. 

While i agree that water - that good, natural, sweet fuel everyone needs - should remain in the commons, i'd like to know 
1. what steps are being taken to reduce / eliminate wastage / misuse / overuse?
2. why is RWH not being implemented on war footing?
3. why are RO system vendors allowed to indiscriminately / aggressively market their product as the first and last solution to obtain potable water?

Delhi should not be pampered any more. The earlier netas and citizens realize this, the better or the entire nation.

"Delhi’s water demand, according to the DJB, is 4,903 million litres daily (MLD) but the total supply is 3,995 MLD. Of this, according to the Centre for Science and Environment, 52% is lost to leakage.

This projected total demand in 2017 is expected to rise to 5,130 MLD.

Delhi needs additional 80 million gallons water per day (MGD) from Haryana. The Renuka dam in Himachal promises to bring in another 275 MGD in the next decade. Recent reports say Haryana has been not releasing enough water into the Yamuna to maintain production in Delhi, causing officials to panic.

So why such scarcity of water in a city that has flourished for hundreds of years? For centuries, Delhi’s primary source of water used to be its water bodies — wells and ponds. As the population increased, the demand rose, putting pressure on the earlier “ample” water supply. The city had to look for other sources — the Yamuna basin and groundwater.

Now the main source remains surface water from the Yamuna basin from where it gets 735 MGD. With only a slim chance of getting additional river water, groundwater is the only hope. But that too is under threat. Surface water accounts for 88% of the city’s water supply.

The groundwater level has been going down. This means one would have to dig deeper to find water. An analysis of the last 10 years shows the overall groundwater level is going down by .02 to 1.44 metres per year because of increased extraction and reduced natural recharge." (source)
