India has various kinds of terrain which is challenging prospect when it comes to water conservation. Here are ten traditional methods that are still used.
Having a varied terrain India poses a challenging prospect when it comes to water conservation and water usage. One particular solution is thus not applicable to different areas of the country. In addition, while the use of technology and advancement of science can provide ready solutions, sometimes, traditional time-tested ways can help fulfil the requirements of people in a much more effective way.
Here is a list of some of the traditional water conservation systems that are still in use:
Kul
Kuls are diversion channels that carry water from a glacier to village. Often spanning long distances, with some over 10 km long, kuls have been around for centuries. They are the lifeline of people of Spiti valley of Himachal Pradesh and in Jammu too.
Kul starts at the glacier, which is to be tapped. Keeping the head clear of debris is achieved by lining the sides of Kul with stones which ensure that there is no seepage or clogging. The Kul leads to the village where the water is stored in a circular water tank. The water is drawn from here are per the need of the village.
Bamboo Drip Irrigation System
This system of water conservation and usage of stream and spring water is done using bamboo pipes. Practised in Meghalaya, its primary purpose is to irrigate plantations. This 200-year-old system involves 18-20 litres of water entering the bamboo pipe system every minute to irrigate the fields downhill. A brilliant drip irrigation system, it uses bamboos of various sizes and reduces the output to to 20-80 drops per minute, which is splendid for betel leaf and black pepper crops.
The whole irrigation system is made up of different forms of bamboo pipes of varying cross sections which take the water from perennial springs on the tops of the hill. The flow of water is controlled by the changing pipes positions. The method is so efficient that it enables the water to be dropped at the base of the plant to ensure there is no runoff and wastage.
Johads
Alwar district of Rajasthan is one of the driest regions in India with water scarcity being a common occurrence. After the drought of the 1980s, the villagers attempted to revive the traditional method. Johad, a crescent shaped small check dam built from earth and rock to intercept and conserve rainwater, was thus reinvented. This helps to improve percolation and increases groundwater recharge.
By recharging the aquifer below the surface, Johads have helped increase agriculture in the area. Usage of Johads has also helped increase the flow of river Arvari, making it a perennial river now. It earlier used to dry off after the monsoon.
Zabo
Zabo means impounding water. Known locally as the Ruza system, this system is a unique combination of water conservation with animal care, forests and agriculture. Mostly practised in Nagaland, Zabo is used to deal with a lack of drinking water supply. During monsoon, rainwater that falls on the hilltops is collected into the pond like structures that are carved out on the hillsides. The water is then passed onto cattle yards below from where the water enters the paddy fields rich in manure.
The paddy fields can be used to rear fishes as well thus giving a yield of about 50-60 kg/ hectare as extra output. Quite a few medicinal plants and herbs are also grown nearby. These ponds are made in such a way that water distribution is uniform.
Eri
One of the oldest water conservation systems in India, Eri (tank) of Tamil Nadu is still widely used around the State. With over a third of irrigation in the State being made possible due to Eri, the traditional water harvesting system plays an important part in the agriculture. They also have other advantages such as prevention of soil erosion, recharge of groundwater, and flood control.
Eri can either be fed through channels that divert river water, or rain-fed ones. They are usually interconnected to balance the water in case of excess or lesser supply.
Khadin
Khadin is a water conservation system designed to store surface runoff water for the purpose of agriculture. It entails an embankment built around a slope, which collects the rainwater in an agricultural field. This helps moisten the soil and helps in preventing the loss of topsoil. Additionally, spillways are provided to ensure that excess water is drained off.
This system of water conservation is common in the areas of Jaisalmer and Barmer in Rajasthan. A dug well is usually made a bit further from Khadin to additionally take advantage of groundwater recharging that happens around the structure.
Virdas
Developed by the nomadic Maldhari tribes of Rann Of Kutch, virdas are shallow wells dug within a natural depression(Jheel). Since the area around is very saline, when rainwater seeps down the soil, it collects over the saline groundwater due to the difference in density (rainwater being less dense). The tribesmen identify areas on basis of flow of the monsoon runoff and build these shallow wells.
This smart method helps them separate freshwater from saltwater and provide water for a variety of purposes. Vegetation is planted along virdas to help protect them.
Surangam
Surangam is a traditional water conservation system present in areas of Karnataka and Kerala. The terrain of the area makes it impossible for people living around to survive only on surface water. Thus a complex labyrinth of fine tunnels are built which constitutes horizontal wells dug in laterite rocks. The Surangam can be of varying length and can even go up to 300 metres. Water is collected into a storage tank using gravitational force. Vertical shafts are provided for airflow.
The population nearby depends mainly on these horizontal wells for their water requirements. They are also used to irrigate crops such as paddy and coconut. What is also important that the water from Surangam is of good quality.
Ahar Pynes
This is a water conservation technique indigenous to South Bihar. Due to a variety of reasons including sandy soil, temporal river flow, low groundwater levels etc, floodwater harvesting is considered as the most suitable option for the area.
Ahar consists of a catchment basin embanked on three sides, at the end of a rivulet or a canal that leads from a river. Pynes are artificial channels, which were constructed to use river water for agriculture. The process starts from the river, from where the water goes to pynes and eventually lands up in an ahar. Although the system suffered under British rule, it has again been rejuvenated for agricultural purposes, especially in the district of Gaya.
Kunds/Kundis
With the look of an upturned cup nestling in a saucer, these water conservation structures are built to harvest rainwater. Usually dotting the areas of Rajasthan and Gujarat, they have a saucer shaped catchment area sloping towards the centre to where the well is situated.
To prevent debris from falling into the well, a wire mesh is used while the sides of the well pit are covered with lime and ash, which act as a disinfectant. Usually, the depth and diameter of these kunds depend upon the purpose of use i.e. drinking or for domestic usage.
There are many other methods too that are practised in various combinations. These methods have been around for hundreds of years, and with a lot of areas suffering from water scarcity, it may be time to revisit some other traditional methods to help innovate new ways of revival.
Using these methods, we can help combat monsoon failure by rain water conservation

Petrol in India is cheaper than in countries like Hong Kong, Germany and the UK but costlier than in China, Brazil, Japan, the US, Russia, Pakistan and Sri Lanka, a Bank of Baroda Economics Research report showed.
Rising fuel prices in India have led to considerable debate on which government, state or central, should be lowering their taxes to keep prices under control.
The rise in fuel prices is mainly due to the global price of crude oil (raw material for making petrol and diesel) going up. Further, a stronger dollar has added to the cost of crude oil.
Amongst comparable countries (per capita wise), prices in India are higher than those in Vietnam, Kenya, Ukraine, Bangladesh, Nepal, Pakistan, Sri Lanka, and Venezuela. Countries that are major oil producers have much lower prices.
In the report, the Philippines has a comparable petrol price but has a per capita income higher than India by over 50 per cent.
Countries which have a lower per capita income like Kenya, Bangladesh, Nepal, Pakistan, and Venezuela have much lower prices of petrol and hence are impacted less than India.
“Therefore there is still a strong case for the government to consider lowering the taxes on fuel to protect the interest of the people,” the report argued.
India is the world’s third-biggest oil consuming and importing nation. It imports 85 per cent of its oil needs and so prices retail fuel at import parity rates.
With the global surge in energy prices, the cost of producing petrol, diesel and other petroleum products also went up for oil companies in India.
They raised petrol and diesel prices by Rs 10 a litre in just over a fortnight beginning March 22 but hit a pause button soon after as the move faced criticism and the opposition parties asked the government to cut taxes instead.
India imports most of its oil from a group of countries called the ‘OPEC +’ (i.e, Iran, Iraq, Saudi Arabia, Venezuela, Kuwait, United Arab Emirates, Russia, etc), which produces 40% of the world’s crude oil.
As they have the power to dictate fuel supply and prices, their decision of limiting the global supply reduces supply in India, thus raising prices
The government charges about 167% tax (excise) on petrol and 129% on diesel as compared to US (20%), UK (62%), Italy and Germany (65%).
The abominable excise duty is 2/3rd of the cost, and the base price, dealer commission and freight form the rest.
Here is an approximate break-up (in Rs):
a)Base Price | 39 |
b)Freight | 0.34 |
c) Price Charged to Dealers = (a+b) | 39.34 |
d) Excise Duty | 40.17 |
e) Dealer Commission | 4.68 |
f) VAT | 25.35 |
g) Retail Selling Price | 109.54 |
Looked closely, much of the cost of petrol and diesel is due to higher tax rate by govt, specifically excise duty.
So the question is why government is not reducing the prices ?
India, being a developing country, it does require gigantic amount of funding for its infrastructure projects as well as welfare schemes.
However, we as a society is yet to be tax-compliant. Many people evade the direct tax and that’s the reason why govt’s hands are tied. Govt. needs the money to fund various programs and at the same time it is not generating enough revenue from direct taxes.
That’s the reason why, govt is bumping up its revenue through higher indirect taxes such as GST or excise duty as in the case of petrol and diesel.
Direct taxes are progressive as it taxes according to an individuals’ income however indirect tax such as excise duty or GST are regressive in the sense that the poorest of the poor and richest of the rich have to pay the same amount.
Does not matter, if you are an auto-driver or owner of a Mercedes, end of the day both pay the same price for petrol/diesel-that’s why it is regressive in nature.
But unlike direct tax where tax evasion is rampant, indirect tax can not be evaded due to their very nature and as long as huge no of Indians keep evading direct taxes, indirect tax such as excise duty will be difficult for the govt to reduce, because it may reduce the revenue and hamper may programs of the govt.
Globally, around 80% of wastewater flows back into the ecosystem without being treated or reused, according to the United Nations.
This can pose a significant environmental and health threat.
In the absence of cost-effective, sustainable, disruptive water management solutions, about 70% of sewage is discharged untreated into India’s water bodies.
A staggering 21% of diseases are caused by contaminated water in India, according to the World Bank, and one in five children die before their fifth birthday because of poor sanitation and hygiene conditions, according to Startup India.
As we confront these public health challenges emerging out of environmental concerns, expanding the scope of public health/environmental engineering science becomes pivotal.
For India to achieve its sustainable development goals of clean water and sanitation and to address the growing demands for water consumption and preservation of both surface water bodies and groundwater resources, it is essential to find and implement innovative ways of treating wastewater.
It is in this context why the specialised cadre of public health engineers, also known as sanitation engineers or environmental engineers, is best suited to provide the growing urban and rural water supply and to manage solid waste and wastewater.
Traditionally, engineering and public health have been understood as different fields.
Currently in India, civil engineering incorporates a course or two on environmental engineering for students to learn about wastewater management as a part of their pre-service and in-service training.
Most often, civil engineers do not have adequate skills to address public health problems. And public health professionals do not have adequate engineering skills.
India aims to supply 55 litres of water per person per day by 2024 under its Jal Jeevan Mission to install functional household tap connections.
The goal of reaching every rural household with functional tap water can be achieved in a sustainable and resilient manner only if the cadre of public health engineers is expanded and strengthened.
In India, public health engineering is executed by the Public Works Department or by health officials.
This differs from international trends. To manage a wastewater treatment plant in Europe, for example, a candidate must specialise in wastewater engineering.
Furthermore, public health engineering should be developed as an interdisciplinary field. Engineers can significantly contribute to public health in defining what is possible, identifying limitations, and shaping workable solutions with a problem-solving approach.
Similarly, public health professionals can contribute to engineering through well-researched understanding of health issues, measured risks and how course correction can be initiated.
Once both meet, a public health engineer can identify a health risk, work on developing concrete solutions such as new health and safety practices or specialised equipment, in order to correct the safety concern..
There is no doubt that the majority of diseases are water-related, transmitted through consumption of contaminated water, vectors breeding in stagnated water, or lack of adequate quantity of good quality water for proper personal hygiene.
Diseases cannot be contained unless we provide good quality and adequate quantity of water. Most of the world’s diseases can be prevented by considering this.
Training our young minds towards creating sustainable water management systems would be the first step.
Currently, institutions like the Indian Institute of Technology, Madras (IIT-M) are considering initiating public health engineering as a separate discipline.
To leverage this opportunity even further, India needs to scale up in the same direction.
Consider this hypothetical situation: Rajalakshmi, from a remote Karnataka village spots a business opportunity.
She knows that flowers, discarded in the thousands by temples can be handcrafted into incense sticks.
She wants to find a market for the product and hopefully, employ some people to help her. Soon enough though, she discovers that starting a business is a herculean task for a person like her.
There is a laborious process of rules and regulations to go through, bribes to pay on the way and no actual means to transport her product to its market.
After making her first batch of agarbathis and taking it to Bengaluru by bus, she decides the venture is not easy and gives up.
On the flipside of this is a young entrepreneur in Bengaluru. Let’s call him Deepak. He wants to start an internet-based business selling sustainably made agarbathis.
He has no trouble getting investors and to mobilise supply chains. His paperwork is over in a matter of days and his business is set up quickly and ready to grow.
Never mind that the business is built on aggregation of small sellers who will not see half the profit .
Is this scenario really all that hypothetical or emblematic of how we think about entrepreneurship in India?
Between our national obsession with unicorns on one side and glorifying the person running a pakora stall for survival as an example of viable entrepreneurship on the other, is the middle ground in entrepreneurship—a space that should have seen millions of thriving small and medium businesses, but remains so sparsely occupied that you could almost miss it.
If we are to achieve meaningful economic growth in our country, we need to incorporate, in our national conversation on entrepreneurship, ways of addressing the missing middle.
Spread out across India’s small towns and cities, this is a class of entrepreneurs that have been hit by a triple wave over the last five years, buffeted first by the inadvertent fallout of demonetization, being unprepared for GST, and then by the endless pain of the covid-19 pandemic.
As we finally appear to be reaching some level of normality, now is the opportune time to identify the kind of industries that make up this layer, the opportunities they should be afforded, and the best ways to scale up their functioning in the shortest time frame.
But, why pay so much attention to these industries when we should be celebrating, as we do, our booming startup space?
It is indeed true that India has the third largest number of unicorns in the world now, adding 42 in 2021 alone. Braving all the disruptions of the pandemic, it was a year in which Indian startups raised $24.1 billion in equity investments, according to a NASSCOM-Zinnov report last year.
However, this is a story of lopsided growth.
The cities of Bengaluru, Delhi/NCR, and Mumbai together claim three-fourths of these startup deals while emerging hubs like Ahmedabad, Coimbatore, and Jaipur account for the rest.
This leap in the startup space has created 6.6 lakh direct jobs and a few million indirect jobs. Is that good enough for a country that sends 12 million fresh graduates to its workforce every year?
It doesn’t even make a dent on arguably our biggest unemployment in recent history—in April 2020 when the country shutdown to battle covid-19.
Technology-intensive start-ups are constrained in their ability to create jobs—and hybrid work models and artificial intelligence (AI) have further accelerated unemployment.
What we need to focus on, therefore, is the labour-intensive micro, small and medium enterprise (MSME). Here, we begin to get to a definitional notion of what we called the mundane middle and the problems it currently faces.
India has an estimated 63 million enterprises. But, out of 100 companies, 95 are micro enterprises—employing less than five people, four are small to medium and barely one is large.
The questions to ask are: why are Indian MSMEs failing to grow from micro to small and medium and then be spurred on to make the leap into large companies?
At the Global Alliance for Mass Entrepreneurship (GAME), we have advocated for a National Mission for Mass Entrepreneurship, the need for which is more pronounced now than ever before.
Whenever India has worked to achieve a significant economic milestone in a limited span of time, it has worked best in mission mode. Think of the Green Revolution or Operation Flood.
From across various states, there are enough examples of approaches that work to catalyse mass entrepreneurship.
The introduction of entrepreneurship mindset curriculum (EMC) in schools through alliance mode of working by a number of agencies has shown significant improvement in academic and life outcomes.
Through creative teaching methods, students are encouraged to inculcate 21st century skills like creativity, problem solving, critical thinking and leadership which are not only foundational for entrepreneurship but essential to thrive in our complex world.
Udhyam Learning Foundation has been involved with the Government of Delhi since 2018 to help young people across over 1,000 schools to develop an entrepreneurial mindset.
One pilot programme introduced the concept of ‘seed money’ and saw 41 students turn their ideas into profit-making ventures. Other programmes teach qualities like grit and resourcefulness.
If you think these are isolated examples, consider some larger data trends.
The Observer Research Foundation and The World Economic Forum released the Young India and Work: A Survey of Youth Aspirations in 2018.
When asked which type of work arrangement they prefer, 49% of the youth surveyed said they prefer a job in the public sector.
However, 38% selected self-employment as an entrepreneur as their ideal type of job. The spirit of entrepreneurship is latent and waiting to be unleashed.
The same can be said for building networks of successful women entrepreneurs—so crucial when the participation of women in the Indian economy has declined to an abysmal 20%.
The majority of India’s 63 million firms are informal —fewer than 20% are registered for GST.
Research shows that companies that start out as formal enterprises become two-three times more productive than a similar informal business.
So why do firms prefer to be informal? In most cases, it’s because of the sheer cost and difficulty of complying with the different regulations.
We have academia and non-profits working as ecosystem enablers providing insights and evidence-based models for growth. We have large private corporations and philanthropic and funding agencies ready to invest.
It should be in the scope of a National Mass Entrepreneurship Mission to bring all of them together to work in mission mode so that the gap between thought leadership and action can finally be bridged.
