Importance of water management in developing countries

May 22, 2012 - PRLog -- The city of Tughlaqabad, the previous kingdom of Delhi, was abandoned within the fourteen century owing to severe water shortage. Akbar's capital at Fatehpur Sikri was abandoned in 1585 owing to paucity of water. Leading international cities like Sheba and Babel declined and subsequently disappeared as a result of water sources had dried up.

The destiny of a number of the best cities of the planet like ny, London, Paris and Rome are formed by water. Water is that the essential resource which may enhance India's economic growth, improve the standard of lifetime of its folks and guarantee environmental sustainability. Climate changes and overuse of water may mean that just about one in each 2 persons can live in water-stressed areas. Households, business and agriculture can increasingly compete for water, leaving very little to sustain ecosystems.

Urbanisation are the defining feature of India's growth within the coming back years; many studies have projected that it'll happen on an unprecedented scale. 350 million a lot of of India's population can move to cities by 2030. This population can double by 2050. That is 2.5 times the dimensions of the US's gift population and would be the most important urban movement within the history of the planet. this is often a novel chance for India to form next generation infrastructure; to set up, develop and manage cities that are socially equitable and environmentally sustainable. The governance and management of water holds the key to India's future.

The problem as of now could be not of availability of water. the problems are optimal management, a far better distribution mechanism, reduction of high rates of leak-ages, retreating wastewater and harvesting rainwater. If these problems don't seem to be treated as utmost priorities, India can got to think about highly expensive solutions or seriously retard its growth ambitions.

The best thanks to approach these issues is to adopt innovative and futuristic management techniques - minimum use of water, recycling and reusing waste water for industrial uses and making certain a better degree of potency within the management of water use in irrigation. another measures would be the adoption of the newest technologies like desalination in coastal areas and recharging of the groundwater level by suggests that of artificial aquifer recharging and recovery.

A great example of water resource management is Singapore. as a result of water is scarce, Singapore has engineered up huge efficiencies during this space. Rainwater collected from rivers, streams, canals and drains is stored in reservoirs. Water catchments give nearly half Singapore's water wants, with housing developments boasting economical rainwater assortment. All wastewater is collected and therefore the town contains a separate drainage system to confirm it does not combine with run-off. This wastewater and drainage water are each recycled and place into the city's water provide.

The wastewater is purified using advanced membrane technology to supply high-grade reclaimed water. this is often called NEWater that is safe to drink - and being purer than faucet water, it's ideal for industrial uses. nearly ten million gallon of NEWater is mixed with raw reservoir water to become faucet water. Desalinated water using reverse osmosis technique provides 100% of the country's water wants.

On the demand management facet, water charges don't seem to be lump add however primarily based on consumption. The water tariff has many rates for various consumption levels. the fundamental water tariff has increased once a year since 1997. additionally, there's a water servi-cing tax and a waterborne fee to hide the wastewater treatment. The tariff system has signifi-cantly impacted water usage. the town has successfully managed to lower actual water demand whereas each its population and GDP have grown considerably. it's demonstrated that comprehensive water resource management is possible given the political can and an innovative mindset.

What are the teachings for India? Firstly, setting the proper worth for water can encourage folks to waste less and use it efficiently. Secondly, in India agriculture accounts for eighty two of water use as compared to Bastille Day in industrialised countries. The agricultural sector here gets free water provide that has inspired wasteful water use and pollution. Countries like Korea, New Zealand and Australia have demonstrated that decreased water intake will enhance agricultural producti-vity. Australia has managed to chop irrigation water by 0.5 and nonetheless increase agricultural output.

To follow suit - and since of overstressed groundwater in varied regions - we have a tendency to should choose drip irrigation, low water demand crops, recharging of groundwater through rainwater harvesting and use of treated wastewater for improvement in groundwater levels by means of artificial aquifer recharge.

And thirdly, we have a tendency to conjointly have to be compelled to introduce innovation in recycling and reuse of wastewater for industrial use, moreover as usher in the newest technologies for desalination.

A fascinating study by the Centre for college for Science & atmosphere - titled 'Excreta Matters: How urban India is absorbing water, polluting rivers and drowning in its own excreta' - has shown that just about seventieth of Jawaharlal Nehru National Urban Renewal Mission allocations have gone into the creation of costly hardware for water and sewage treatment while not vital gains. the solution lies in native solutions, community participation, reviving native water bodies, higher distribution and management and recycling each single drop of wastewater. India's ability to manage and govern water can verify its destiny.
