Fluoride free drinking water supply in North Gujarat: The rise of Reverse Osmosis plants as a cottage industry - A study by CAREWATER

The study by Carewater INREM Foundation explores the rise of Reverse Osmosis (RO) plants since 1970s as a cottage industry for providing fluoride free water supply in North Gujarat. The emergence of markets for Reverse Osmosis (RO) plants can be attributed to the Government’s failure in supplying large-scale safe water to the public through its large RO and de-fluoridation plants.

A detailed study was undertaken of 8-10 plants in 4-5 towns in Mehsana district so as to understand the economics, volumes of business, prices, modes of business and the nature & economic profile of the clientele. The future prospect of the industry is assessed, especially focusing on growth rates through discussions with plant owners, customers and municipal leaders.

The study concludes the following - 

  • The market for the mineral/packed water produced by cottage industries has developed very rapidly in North Gujarat between 1996 and 2000.
  • The small pouches bring more margins as compared to big-packs of 10 or 20 litres. Producing packed water in pouches requires an additional investment of rupees one lakh in a packaging machine, which the investors find affordable. The packed drinking water in pouches has a large market catering to the people at large.
  • As long as the municipality’s supply of groundwater in North Gujarat is high on TDS and has more than recommended amount of fluoride, packaged drinking water has a good market.
  • There is good growth of this cottage RO industry as the market is very wide. Even if the ISI certification is made mandatory, there are a good number of investors keen on investing in it.

Reverse Osmosis plants for rural water treatment in Gujarat - A study by CAREWATER

carewaterThe report by Carewater INREM Foundation deals with Reverse Osmosis (RO) technology, which is emerging as an important solution for drinking water treatment in rural Gujarat. RO plants with capacity ranging from 10 litres per hour (lph) to 6000 lph are now supplying drinking water in several hundred villages of the State. Small sized plants with capacity < 20 lph are used by individual families whereas medium to large sized plants (>100 lph) are being used for public consumption.Read More

Groundwater and well water quality in alluvial aquifer of Central Gujarat - A paper by CAREWATER

carewaterThe report by Carewater INREM Foundation deals with groundwater and well water quality in the alluvial aquifers of Central Gujarat. Gujarat has a hydrogeology representative of almost all aquifer types and depositional & formation eras. Contamination of aquifers along with scarcity of groundwater resources due to increase in water demand and reduction in recharge of groundwater from changing landuse, is a problem in Central Gujarat.Read More

Arsenic contamination of groundwater in Bihar and mitigation strategies - A research study

Arsenic contamination of groundwater of Bihar and mitigation strategies - Map 2009This presentation deals with the problem of arsenic contaminated aquifers in the Gangetic belt of Bihar and the failure of the state government in tackling the crisis and calls for the establishment of a centralized knowledge & research hub with an understanding of the regional peculiarities to mitigate the crisis.Read More

It traces the origin of arsenic crisis to the switch from use of surface water to groundwater. The health impacts of arsenic poisoning and the factors that aggravate arsenicosis are explained. A total of sixteen districts (fifty-seven blocks) in Bihar are affected by high levels of arsenic in groundwater, in trivalent form, which is a more toxic form of arsenic.

Fluoride-free drinking water supply in North Gujarat - The rise of reverse osmosis plants as a cottage industry

This study by Carewater focuses on the large number of ‘cottage’ type  Reverse Osmosis (RO) plants that came to be marketed for supplying good and safe water to the consumers under ‘packed drinking water’ category, and a big market for which emerged in North Gujarat. For the purposes of this study, ‘fluoride-free water’ means treated water containing prescribed quantity of fluoride and not completely ‘fluoride-free’.  The objective was to study these plants, its clientele and to estimate the future of this ‘sunrise’ industry.Read More
