3. RATIONALE AND CONTEXT
• Nearly 90 lakh farmers in Maharashtra have been impacted by
the drought that has devastated the kharif crop, official data
shows.
• The current problems faced by farmers are
-Social: Money lending which is banned in India is
still prevalent and leads to exploitation of farmers
especially when the yield is low.
-Economic: most of the government projects
concentrate more on building dams and canals
which take years to complete.

4. – Political: Though water is constitutionally a state subject,
in many ways it has stayed a central one. While the
Constitution mandates panchayats to control and manage
water at the local level, India’s water policy reflects
centralization
 This calls for a cheap and sustainable small scale irrigation
model which can convincingly solve the basic issues at hand
over a small period of time.

5. LITERATURE SURVEY
Every day, Maharashtra is shaken by the news of farmer suicides in Vidarbha
or Marathwada.
• According to P. Sainath , between 1995 and 2013 Maharashtra had the
highest numbers of Farmer suicides in the country: An
unbelievable 60,750 farmers committed suicide during this period.
• One of the reasons is that Agrarian crisis in Vidarbha and Marathwada has
too many facets: National agricultural policies, lack of rational water policy,
absence of irrigation, huge irrigation backlog, thirsty and expensive GM
cotton, diversion of irrigation water from farms to power plants &
industries, bad crop insurance policies, hopeless revenue tools of arriving
at farm losses issues with household economic management by farmers,
opportunistic lenders and opportunistic leaders… and an indifferent society
as a whole.
WE ALL ARE RESPONSIBLE FOR MAKING THE SITUATION BLEAK.

6. OBJECTIVES
• To make water available for agriculture during
extreme drought-like conditions.
• Sewage treatment using distillation without any
consumption of fuel or electricity.
• Use of treated water for drip irrigation to maintain
the water level between field capacity and
temporary wilting point.

9. STAKEHOLDERS
• Active NGOs working in the area should be
convinced about the idea and its outcomes. They can
help promote as well as fund the idea.
• PWD can fund the project once its credibility for
short term goals is proved by proper modeling of the
idea.

11. SUSTAINABILTY
• This idea can sustain because
1. Technically it requires very less skill for
maintenance.
2. Socially there will be no issues of ownership since
sewage water from every household can be used.
3. It will gain political support since it is an idea to end
misery of farmers till government plans and
implements new schemes and projects.

12. INNOVATION
• Use of renewable energy for treatment of water without
consumption of fuel.
• Use of perforated cylinders for optimal subsurface water
content determination.
• Sensors to detect the water level in perforated cylinder
and actuate outflow of tank.
• A plan to solve the grass root problem( improving the
irrigation system) rather than direct compensation to the
farmers.

13. OUTCOMES
• Reduces the burden of farmers to rely on monsoon
• utilization of sewage and wastewater for agricultural usage thus reducing the
contamination problem, transportation of sewage to dumping areas and helps in
maintaining a clean environment.
• purification of the sewage water in a cost effective way so that every farmer can
install this technique individually. This purification involves chemical free and
primary purification sufficient to make the waster fit for cultivation.
• this system provide a detention time of two to three months for storage of water
to use it in case of scarcity and thus provides supply of water to crop even in
scanty rainfall conditions.
• use of the sludge obtained from the treatment process as fertilizers thus not
involving the use of fertilizers which are posing a harm to groundwater as well as
soil as natural resources.
• automated sensors to activate the water supply from detention tank thus ensuring
optimum usage of water and reducing inundation of fields.

14. IMPACTS
Short term impacts:
• Self-sufficient farmers.
• Waste utilization.
• Happy and stress free life.
• No dependence on money lenders.
Long term impacts:
• Futile to fertile soil.
• More people will turn to agriculture if condition of farmers
improves thus increasing the net produce of the country.
• Economic growth would be the direct result of self-
sufficient and well planned farming techniques.
• Reduction in dependency on rains for farming.

15. LINKAGE TO ONGOING SCHEMES
Vidarbha Intensive Irrigation Development Programme(VIIDP)
Expansion of Micro Irrigation
System and Supply of Water
lifting Devices:
This intervention will include
application devices like drip
system sprinkler sets etc.
Formation of Water Users
Associations and Farmer
Groups:
The program envisages
better utilization of created
potential through formation
of sufficient number of
Water Users Associations
and Farmers Groups
Restoration of Minor
Irrigation Potential: There
are many minor irrigation
(less than 250 ha)
schemes, which due to
insufficient maintenance,
have virtually lost their
Utilities . This program
aims at improving them.
OUR MODEL CAN BE LINKED TO THE PROGRAM AS FOLLOWS

16. CONCLUSIONS
In absence of optimum water
requirement devices for plants ,
wastage is a problem because of
inundation.
To curb this problem perforated
cylinders for optimum water
requirement are suggested

CONCLUSIONS
To efficiently irrigate the farm land considering the scarcity , drip
irrigation is such a system which makes use of minimal water.

18. • Treatment processes,mainly primary
sedimentation and distillation being
extensively used to channelize sludge-free
water for irrigation.
