Hydro-powering regional development in India and Nepal

Socially and economically, the performance of the four northern Indian states (Bihar, Madhya Pradesh, Rajasthan and Uttar Pradesh) collectively known as BIMARU (meaning ‘sick’ in Hindi) and neighbouring Nepal has left much to be desired. Together, they constitute one of the most deprived regions of the world. But tapping the region’s water resources may just quench its thirst for development.

With a population of 103 million, Bihar is nearly four times the size of neighbouring Nepal (28 million). But per capita income in Bihar was only 40.6 per cent of the Indian average in 2014–15, and nearly one in three of India’s poor live in the state. The situation is much worse in Bihar’s rural north.

Across the border, Nepal shares many similar characteristics. One in four Nepalese live below the poverty line and nearly 80 per cent of the population live in rural areas. In the mid-west and far-west regions, rural poverty is around 45 per cent.

As in Nepal, agriculture is the largest employment sector in Bihar (80 per cent), but contributes only 20 per cent to its GDP. Endemic unemployment and underemployment are common problems and many migrate to find employment: Biharis to other Indian states, and Nepalese to wealthier Middle Eastern and Southeast Asian countries. There they are mostly employed in so-called ‘3D jobs’: dirty, difficult and dangerous.

A good starting point to improve the economic situation in both Bihar and Nepal could be developing transboundary rivers, which have huge hydropower and irrigation potential. Properly planned, these rivers can act as an engine for regional development. Nepal has very large hydropower potential (42,133 megawatts), only 2 per cent of which has been developed. India’s potential is 150,000 megawatts, 73 per cent of which remains undeveloped. Since hydropower is a non-consumptive user of water, it can also be used for irrigation after power generation. Both Nepal and Bihar suffer from a lack of assured water supply for all uses.

Such development in Nepal and Bihar could start with the Kosi River basin. The 88,000 square kilometre basin is Nepal’s largest and home to over 40 million people across Nepal and India. Floods are a serious hazard. But the river also has enormous hydropower and irrigation potential.

In India, the Kosi River catchment covers only one state: Bihar. This is a unique advantage since water is a state subject in India. All other major transboundary river basins in Nepal and India cross state boundaries. If two or more states are involved, the complexities of even reaching an agreement between them, the Indian Government, and finally Nepal, are likely to increase many-fold.

A good development plan, with structural and non-structural flood control measures, will also significantly improve economic conditions for millions of people in the basin.

To reduce flood hazards, under the 1954 Kosi Treaty between India and Nepal, India designed, built and maintains the Kosi barrage in Nepal, as well as a 32 kilometre stretch of embankments in Nepalese territory. Since its completion in 1959, the structures have impeded the flow of high sediment loads in the river, which have instead built up on the river bed. Over time, the bed level of the Kosi River in many places rose four metres higher than the surrounding land.

On 18 August 2008 the Kosi embankment broke, triggering India’s worst flood disaster in 50 years. Affecting 3.3 million people, it caused over US$1.2 billion in damage. Crops were lost across 600,000 acres of land, affecting some 500,000 farmers and damaging 300,000 houses.

Surprisingly, the water level of the 2008 flood was not particularly high. But because of endemic corruption among Indian and Nepali contractors, politicians and bureaucrats, the embankments were neither properly constructed nor properly monitored and maintained. The floods were a disaster waiting to happen.

The Kosi Treaty also has fundamental structural problems. Bihar’s — not Nepal’s — Water Resources Department (WRD) is responsible for monitoring and maintaining the embankments in Nepal. Yet the WRD must go through India’s national government to communicate with the Nepalese government, delaying responses to flood emergencies. India and Nepal need to forge better relations and formulate and implement sustainable plans for managing their transboundary rivers, especially the Kosi.

The timing now seems to be right with improved relations between Bangladesh, Bhutan, India and Nepal (BBIN). At the BBIN subgroup meeting in Dhaka in January 2016, the four countries agreed to work on specific water projects, electricity trade, inter-grid connectivity, and flood forecasting. This presents a significant win-win opportunity for all four if this development progresses further.

Nepal and Bhutan can develop hydropower which their energy-hungry neighbours India and Bangladesh can use after domestic needs have been met. India can provide transmission lines in small sections of its territory to connect the electricity supply to Bangladesh. As a quid pro quo , Bangladesh could grant transhipment rights through its territory so that goods could be transported by road to north-eastern India. With some give and take, a BBIN regional agreement could take shape which would significantly improve their economic and social conditions, and potentially increase India’s trade with South Asia by about 60 per cent.

This integration and cooperation could be further aided by a neutral and competent ‘honest broker’ in the form of the International Centre for Integrated Mountain Development (ICIMOD). ICIMOD can also provide expertise on issues such as climate change and flood warning systems to help formulate appropriate development policies.

But regional cooperation will not be easy. India and Nepal must first overcome decades of mistrust and hostility. Then there is the thriving informal economy. Rent-seekers are doing a roaring trade due to inefficiencies, non-transparency and the inadequacy of trade facilities between Nepal and Bihar. These rent-seekers are politically and bureaucratically well-connected and will strongly resist any attempt to streamline trade and current transportation logistics.

Still, despite these constraints, there are no real alternatives to sustainably developing transboundary rivers like the Kosi. Such development will alleviate poverty for millions of people within a reasonable timeframe.

Regional Cooperation in water resources development of Nepal would benefit this region but as of now  even the bilateral cooperation between Nepal and India is also not implemented as reflected in the non implementation of Mahakali Treaty on water resources development.

the existence of ocean currents has opened the mind to myself of the opportunity to produce energy by recycling the water, because inside the volume of water accumulated you can harness the energy position of the water surface respect to water placed in the bottom, as long as there is content to use only the water specifically ducted from the surface, pulled down by a pump inverted, placed in the bottom, which feeds a turbine.  This system does not exploit the hydrostatic pressure of the basin but the dynamic pressure that develops in the descent tube due to the rotation of the pump. The turbine, placed after the pump slows down the velocity of water in the descent tube, that would assume the value (V = √ 2 gh) increased by the force of gravity and by atmospheric pressure, that the pump would not be able to control by itself, producing hydroelectric energy instead of dissipating it as heat both in the downhill tube, both in the submerged outlet.  The concept of energy of position without the hydraulic jump is understandable even by the drilling of a submerged water vein that spontaneously produces the water output from the subsoil to the effect of atmospheric pressure acting on the water surface of the basin that feeds the vein. In the compressed hydroelectric, we use the same energy principle, but replacing the atmospheric pressure with an artificial pressure, which can be thirty - forty times higher than atmospheric pressure, thereby producing an energy thirty - forty times higher. But to produce energy by recycling the water and without consuming the air cushion is necessary to circulate the water inside the pressurized tank one-way, not like the current autoclaves, where the water comes in and out by the same hole by expanding and compressing  the air cushion. The expansion involves a loss of energy, because it requires a subsequent compression and therefore there is not an energy gain. Instead, the energy gain is obtained by circulating, in one way, a part of the water incompressible under the compressed air cushion keeping constant the two volumes inside the tank. Therefore, we only exploit the water that comes from the pressurized tank, as if it came from the overflow of a reservoir at atmospheric pressure, but since the pressure is much higher than atmospheric and replaces the height h in the formula (V = √ 2 gh), we have a multiplication of energy produced in the turbine that is proportional to the pressure of the air cushion, which does not lose its thrust because it does not expand, as it not expands the atmospheric pressure on open basins. For this to happen, it is necessary that the amount of water that enters into pressurized tank is exactly equal to that leaving powering the turbine. This takes place by means of the pump with the double separate power supply up to the impeller, specially invented by myself, which has the power that has the power to recycle the water in two separate circuits aspirants, but with only one outlet placed in the  pressurized tank. Therefore, the internal recycling circuit of the pressurized tank is balanced by the static pressure of the air cushion, which acts in the impeller of the pump suction and delivery, while the other power supply of the impeller, hermetically separated from the first, when the impeller rotates, makes enter in the pressurized tank also the water discharged into an open tank from the turbine. But the pressurized tank having already occupied the volume of water and the air cushion expels again the same amount of water which enters, with all its strength, without expanding the air volume, allowing it to enter back into the turbine, in an infinite loop.  Obviously, this circuit can be realized in many versions and in many sizes to produce energy, fixed and mobile, in proportion to the pressure of the air cushion (which as is known has a critical pressure of 37.5 bar and a critical temperature of - 140 , 6 degrees Celsius), therefore, we could produce energy at very low cost, even at the north pole, in all seasons, for twenty-four hours a day and three hundred sixty-five days a year, since the advent of the industrial age, saving spaces pollution and global warming. Indeed, since, proportionally, to the operating pressure, the water solubilize also the gases present in the air, being important only that the nitrogen percentage is neutral and oxygen, thanks to the latter, with this type of energy, we can practically eliminate the costs of depuration because producing energy with rainwater and waste, continuously, practically without energy costs, we arrive easily endogenous oxidation that consumes all organic substances in the water and if we create artificial rain of calcareous materials in covered environments, in the lower areas of the atmosphere, we can lower the quantity of CO2 in air producing alkaline water, which returns to the sea through rivers fighting acidification and melting glaciers.
