Actually, the water [...]]]> Dwarka Underpass has been in the news for the sheer visual shock of seeing 6m (20ft) high column of water on a road after a more than average rainfall in a single day.

Actually, the water was standing not just in the underpass but also on the road leading into the underpass from both sides. Approximately, 1.5 km stretch of road including the underpass had water logging. The water logging was so bad that, even today, 4 days after the downpour, and hectic efforts to pump out the water, the road is still blocked for traffic. 

As per our calculations, the total volume of water that was standing in this entire area was between 10-12.5 crore (100 -125 Million) liters. If we take Delhi’s average rainfall, then over the year, this area alone would hold approx 40-50 crore (400-500 Million) litres of water!

To put this figure in perspective,

10 crore litres = 7,50,000 people’s requirement for one day or more than 2000 people’s total water requirement for one whole year!

WHY THIS HAPPENS:

1) Faulty drainage planning – An underpass is an artificial depression dug out from the ground. Drainage in an underpass is always a problem because it’s almost always impossible to align the slope of the underpass drainage with that of the main drain outside the underpass (whose level will be higher than the underpass). The problem becomes worse when the underpass is located at a site which is topographically also a naturally depressed zone. In such an area the tendency of water from all the surrounding catchment area is to flow towards that depression with no escape route in sight.

It is important therefore to ensure that the drainage for surrounding catchments is planned in such a way that all water gets diverted away from the underpass BEFORE it enters the depressed zone.

2) Poorly designed / constructed rainwater harvesting systems. As per court orders all flyovers are supposed to do rainwater harvesting. It does not seem like the Dwarka Underpass has done it. Even if it has,

        a) The system is obviously insufficient because its recharge capacities have not been designed after taking into consideration the runoff generated by the entire CATCHMENT of the underpass area.

        b) Poor intake of the system because of faulty design / construction.

        c) The system is poorly maintained. Rainwater harvesting system needs regular cleaning to maximize its intake capacity. If this is not done, the system gets choked and becomes defunct. Its cleaning is especially necessary where the RWH system takes (water from road / open surfaces etc where the silt load is high.

POSSIBLE SOLUTIONS

1) Proper Drainage planning. The Problem can be corrected even now. However, planners will need to look beyond the underpass and plan for catching run-off from the catchment area for the underpass itself.

2) Rainwater Harvesting – All along the 1.5 km stretch, maybe perhaps more (analysis of exact site conditions needs to be made) an extensive rainwater harvesting system needs to be made. This will ensure that the runoff gets recharged to groundwater and there is no surplus flow left to “water-log” the underpass.

POLICY CHANGE NEEDED

The Dwarka Underpass is just a stark reminder of the urgent need to change policies to reflect urban water conditions:

1) WATER PLANNING SHOULD BE AN INTEGRAL PART OF THE DESIGNING WITH INTEGRATED EFFORT FROM ALL AGENCIES: Drainage and Water Harvesting planning to be done by agencies in co-ordination. When the underpass would have been constructed, PWD would have been given jurisdiction only over the immediate stretch of land over which the underpass is to be constructed. Hence, their designing and implementation would have to be a closed loop with minimal co-operation / interface with authorities managing that catchment area roads and drainage. So even if PWD wanted to plan an extensive drainage system, it would not have been able to do so. By the same logic, they might have been aware of / might have been advised by experts to do RWH for the entire catchment but since their intervention area was limited, they might not have been able to implement those suggestions.

2) RAINWATER HARVEQTING SYSTEMS SHOULD BE MADE PART OF THE STORM WATER DRAINAGE SYSTEM. Currently, since RWH is seen as an ad-hoc activity, it is largely unplanned and adequate provisions for maintenance – BOTH OF STRUCTURES AND CATCHMENTS – are not made. RWH systems should be integrated with Storm Water Drainage systems. This will at least ensure that an annual schedule and provision for maintenance will be made by government. It should also be ensured that the catchment conduits for runoff and the RWH systems are maintained simultaneously. This will help ensure efficient working of the systems.

Unless we plan for these now, such fiascos will increasingly occur over time. And why not turn fiascos into opportunities – harvest water from all such areas!

We believe the route to doing so is through mass movements that support local bodies in water conservation and influence the government to adopt more water friendly policies.

We realize that for any sustainable change in basic resource usage patterns, the involvement of all sectors of the society is important.

Citizens, Government and Business must join hands together to achieve the common objective of a better life for all – for us and the generations to come.

Water [...]]]> The U.N. World Water Development Report ranks India 133rd among 180 countries for water availability. India almost hits rock bottom when it comes to water quality. Falling water tables, India’s unpredictable monsoon rains and its huge and growing population have created a severe water crisis in the country.

Water Conflicts, at all levels, are on the rise – both in numbers and intensity. Countries, regions and States are adopting increasingly belligerent stances to lay claim over water resources – static or transient- in their areas.  User groups accuse each other of stealing their water – it’s agriculture vs. industry vs. energy vs. domestic use. All users, however, have no compunctions joining hands to snatch water from its natural abode – it’s All vs. the Environment! On top of that, pollution and global warming add their bit to speeding up our fast drop to water scarcity.

Where will it all end?

A looming crisis brings out either the worst or the best of people. If people decide to put in their best – can success be far behind? Being a die-hard optimist  - I believe the latter. And that’s the guiding sentiment with which we, at FORCE, work.

It’s time now, to revive the Gandhian philosophy of living simply, in tune with nature with each community planning for self sufficiency and sustainability. Greed must be replaced with need based consumption, each one must think for the other, saving for self must not be at the cost of sharing with those in need.

This requires a basic change in attitudes – something that is easier said than done! As a starter, we could start with a simple three point agenda. First – Reduce our demand for fresh water by adopting water conservation practices; second – increase its locally available supply by adopting rainwater harvesting and water recycling. The third agenda, perhaps  most important task is – to stop playing blame games.  Let’s not waste time and energy on blaming each other for inefficiency and callousness. Instead let’s just focus on doing whatever little we can to alleviate this crisis.

With this attitude, FORCE has been working towards creating Water Secure communities – in the National Capital Region of Delhi and now in Mumbai. As a first step, we’d like to see the NCR ‘Water Secure’ by 2015.

The route we have adopted for doing so is through a mass movement that supports local bodies in water conservation and influences the government to adopt more water friendly policies. For this, we’ve adopted a Partnership approach because sustainable change cannot happen without the involvement of all sectors of society. We are getting the citizens, government, business and technical experts to jointly work for a better life for all. We offer end-to-end support to citizen groups interested in adopting water conservation practices.

We believe that seamless knowledge integration – from principles of business management, to practices from many hundred years back,  to advances in science & technology – is the quickest, most effective route to creating a Water Secure society. 

I look forward to having you as a partner on this road to Water Security for all.
