5th Water India 2018 Expo

May 23, 2018 - May 25, 2018


India occupies 2 percent of the world’s land area, represents 16 percent of the world population and 15 percent of livestock, whereas it has only 4 percent of the water resources of the world.

Furthermore, India ranks 133rd out of 180 nations for its water availability and 120th out of 122 nations for its water quality. It has been evaluated that 80 percent of India’s surface is polluted which results in India losing US$ 6 billion every year due to water-related diseases. Challenges faced by the Indian water sector are due to increasing water consumption and wastage in urban areas, water-borne diseases, industrial growth, political and regulatory disputes, water cycle imbalances, increasing irrigation and agricultural demand, lack of technology, etc. According to estimates, India’s water sector requires investment worth US$ 13 billion.

The 5th Water India 2018 expo is an important platform created to show case products, services and solutions available in the water industry worldwide.

The event will provide comprehensive insight into the water industry–best practices, latest technologies, alternative solutions, emerging opportunity and business prospective.

Key segments of 5th Water India 2018 expo

Supply & distribution

  • India is facing water crisis which is expected to worsen as the overall population is expected to increase to 1.6 billion by year 2050
  • According to Central Water Commission (CWC) report, water levels in 91 major reservoirs in the country are at just 25% of capacity—30% lower than last year, and 25% less than the average storage in a decade
  • Reservoirs in India’s eastern and central regions have the most water, with levels at 44 per cent and 36 per cent, respectively, of capacity; while levels in the south, west and north are 20 per cent, 26 per cent and 27 per cent, respectively, according to the CWC data
  • 10-year average for water levels in the country is 38.5 per cent
  • Rs 15,260 crore ($2.77 billion) has been allocated to the Ministry of Drinking Water and Sanitation to expand and improve drinking water supply in the country

Potable drinking water

  • In the urban areas though about 60% of the population is depended on surface water sources, the availability and quality are questionable
  • Rural India lives in about 1.7 million habitations (including villages), three-quarters of which – 1.3 million – gets 40 liters of water per person per day for all uses, including drinking and other usage like bathing, washing clothes, utensils and sanitation
  • There are 66,093 rural habitations in India where the drinking-water source is contaminated with either one or more chemicals, such as arsenic, fluoride, nitrate, iron and salinity; although this is down from 84,292 over two years (Source: IndiaSpend report)
  • It is estimated that around 37.7 million Indians are affected by waterborne diseases annually, 1.5 million children are estimated to die of diarrhea alone and 73 million working days are lost due to waterborne disease each year


Irrigation system

  • Irrigation refers to the supplying water to the dry land as a supplementation of rain water
  • About 68% of the area equipped for irrigation is located in Asia, 17% in the Americas, 9% in Europe, 5% in Africa and 1% in Oceania
  • Major aim of irrigation systems is to help out in growing of agricultural crops and vegetation by maintaining the minimum amount of water required
  • Apart from crop production, it helps in protecting plants against frost, suppressing wild plant growing in grain fields and helping to avert soil consolidation
  •  Irrigation systems are also used for dust repression, removal of sewage, and in mining
  • Types of irrigation systems
    • Surface irrigation
      – Uncontrolled (or wild or free) flooding method
      – Border strip method
      – Check method
      – Basin method
      – Furrow method
    • Subsurface irrigation
    • Sprinkler irrigation
    • Trickle(Drip) irrigation

Water storage systems

  • India’s per capita water storage capacity currently is much below that of China or the United States
  • More than 60 percent of India’s irrigated agriculture and 85 percent of drinking water supplies are dependent on groundwater
  • Water is stored in natural water sources, such as groundwater aquifers, soil waterand natural wetlands
  • It is also stored in small artificial ponds, tanks and reservoirs behind major dams
  • Water recharge/storage/conservation practices from past and present
    • Surface irrigation
    • Katta
    • Sand Bores
    • Johads
    • Bawdi/Jhalara

Wastewater treatment

  • 80 percent of India’s surface water is polluted
  • 75 percent of water pollution is from domestic sewage, which is discharged untreated into local water bodies
    • Grey water is the domestic wastewater from bathrooms (such as basins, showers and baths), laundry fixtures (such as clothes washing machines and laundry troughs) and kitchen facilities (such as sinks and dishwashing machines)
    • Black water refers to wastewater that contains human waste. Black water is collected through toilets and urinals
  • Only 31 percent of urban wastewater is treated per day at 11,787 million litres per day (MLD)
  • The total wastewater generated by the 299 class I cities is 16,662 MLD.  Out of 299 class I cities, 160 cities have sewerage coverage for more than 75% of the population and 92 cities have between 50 and 75% of population coverage
  • India’s total water and wastewater treatment market alone is worth about $420m, growing annually by about 18%


Sewage treatment

  • Only 37 percent of urban sewage is treated per day at 23,277 million litres per day (MLD)
  • Out of 816 municipal sewage treatment plants (STPs) listed across India (522 are operational, 79 STPs don’t work, 145 are under construction, and 70 are proposed)
  • On the whole 70% of the population of class I cities are provided with sewerage facility
  • Delhi has the maximum treatment capacity that is 2330 MLD (30% of the total treatment capacity of metropolitan cities)
  •  Next to Delhi, Mumbai has the capacity of 2130 MLD, which is 26% of total capacity in metropolitan cities


Hazardous waste

  • Hazardous waste is waste that poses substantial or potential threats to public health or the environment
  • According to the Central Pollution Control Board, total hazardous waste generation in India in 2015 was 7.46 million metric tonnes from about 44,000 industries
  • According to a report by Centre for Science & Environment, the entire country has nitrate levels higher than the prescribed levels—a result of sewage leaching into groundwater supplies
  • Improper hazardous-waste storage or disposal frequently contaminates surface and groundwater supplies
  • Dumps and landfills are a threat to water supplies when water percolates through waste


Water sustainability / harvesting / conservation

  • There are various methods of water conservations, including; rainwater harvesting, water recycling, reducing water demand in agriculture sector (efficiency of water use, reducing its loss due to evaporation, improving soil moisture through various techniques like mulching, contour farming, drip irrigation, desalination, etc.)
  • Rainwater harvesting (RWH) is the practice of collecting, storing and distributing rainwater to use it as an alternative source of water
    • Global rainwater harvesting market will witness a CAGR of 4.8% during the period 2016-2020
  • Water recycling is reusing treated wastewater. Water recycling helps to further reclaim water
    • Kuwait, Israel, Singapore and Egypt are leading with 91%, 85%, 35% and 32% of its wastewater reuse, respectively.
    • Water reuse market holds huge opportunity in India where the water recycling rate is less than 20%.
    • Capital expenditure on water reuse is expected to grow at a CAGR of 19.5% while the global installed capacity of high quality water reuse plants is expected to grow from 28 million cubic meters per day to 79 million cubic meters per day
  • Desalination is an energy-intensive process where salt and other minerals are removed from sea water to produce potable water for drinking and irrigation.
    • Two of India’s most industrialised states, Tamil Nadu and Gujarat, are the keen to use desalination technology
  • Waterless toilets
    • On an average 8,300 litres of potable water is consumed in a month by a conventional urinal
    • More than 53 percent of Indian homes — about 70 percent in the villages lack toilets. Poor sanitation and contaminated water cause 80 percent of the diseases afflicting rural India
    • The cost incurred per month actually works out to nearly Rs 2500 per urinal whereas the cost of these waterless installations is just about Rs 5000
    • The average savings per urinal pot including the water  is Rs 30,000 per year
    • Waterless toilets can be effective for rural India, targeting mainly the farming community with the basic premise that there is dearth of water in most rural areas


Solar powered water supply

  • A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps
  • Solar-based dual pump pipe water supply scheme is a viable solution where development of drinking water supply infrastructure is not feasible in inaccessible areas and places having no natural water sources
  • Solar-powered water pumps can deliver drinking water as well as water for livestock or irrigation purposes
  • The advantages of using solar-powered pump are:
    • Low cost
    •  Do not depend upon electricity – Solar power
    •  Easy to operate and maintain
    •  Low recurring costs – No electricity charges
    • Water available throughout the day in houses/at doorsteps
    • Water is supplied right upto houses by taps
