Dhora farmer group organizing
Out of ten proposed sites eight have been completed and work in
two sites is yet to be initiated
5. This stage involves
Details..
► Identification of villages & interaction with the people.
► Organizing community.
► Women Groups/ Institutions were influenced & motivated.
► Need assessment was done
► Farmers group formation
► Encouraging farmers group for periodic meeting and
developing norms.
6. Unfolding Stage 1
► It was difficult to organize the tribal community because of
their busy day to day schedule.
► It was also difficult to convince them of the workability of
the scheme as they were skeptical
► Care was taken for addressing internal conflicts and
where difficult to resolve were left alone for time being.
► As far as possible all decisions were taken in Gram Sabha
► Implementation monitoring committee was formed with
equal participation of people from different caste, gender
and economic strata.
► Where institutions already exist they were given the role of
overseeing and monitoring
7. Unfolding Stage 1
Continued
► Youth from the community were specifically
targeted to ensure greater participation, for
training as resource persons with the objective of:
Assisting in implementation (as para-workers)
Continue assisting when project activity expands
► Formation of farmers group done, however follow
up to develop norms and for agriculture training
and extension pending
8. Major Outcomes of Stage 1
►A detail understanding of village agricultural practices,
irrigation systems, use regimes, conflicts and therefore
possible solutions
► Greater acceptance within the community for the
technology
► Community took the responsibility of execution.
► With the first few sites ready, in areas with conflict
community showed resolve to address these and implement
the project
9. Stage -2 : CONSTRUCTION
Technical planning
Using Loop Software
Permanent layout of trench
Trench digging
Material procurement.
Construction of intake structure.
Laying of pipes.
Covering the trench.
10. Site selection
► Site should be such that the weir and the channel can be
constructed at the least cost
► Site should be such that water availability is ensured
atleast till summer months
► Initial drop of minimum 1m within the first 100m-200m from
sump
► River / Stream reach should be straight and narrow and
have well-defined high banks
► Preferably located where community has some existing
source of irrigation
11. Where are they located
► Rivers have four stages, rocky,
boulder, alluvial and delta
► Rocky is considered unsuitable for
locating the head-works, as the
flow is less, channel construction
is difficult and command area is
away
► Cost of head-works in boulder
stage is less due to availability of
stones locally, smaller width of
river, smaller scour depth and
proximity of higher banks
► The fall in the boulder region may
be used to produce electricity
► A channel off taking in the boulder
stage will require large no of cross
drainage works
► When water is diverted, where the
stream emerges from the hills (as
the slope is steep), it makes
irrigation possible with least cost
12. Technical Planning
► Estimate the discharge of source point
► Using Auto level for Measuring head difference between
source point to end point of scheme .
► Taking RL each 50 m interval and also taking RL junction
point and outlet point with length measurement .
► Determine command area for every outlet.
► Using loop software giving input of field data and generate
Technical report/ feasibility of scheme
13. Trench digging
► Demarcation of surveyed line.
► Maintaining proper depth & width while digging.
► Removing big stones & tree roots/bush clearing coming on
the way.
► Maintaining the slope while digging .
14. Material procurement
► It was done with the joint responsibility of FES and
community people.
► Pipe , pipe fittings were procured after receiving
quotations.
► Boulders, sand & cement were procured by FES based
on requirement.
► Stock register to be maintained preferably at the site level
and if this is not possible atleast at central (team) level
15. Construction of intake structure
► Selecting mason from the
community.
► Digging to make seepage
tank or foundation of
intake tank.
► Transferring boulders
which were locally
available.
► Breaking boulders into
small pebbles to make
concrete.
► Preparing slab to cover
the tank.
16. PVC pipe handling
► Pipe shipment inventoried and inspected
► To prevent PVC pipe from scratching or cracking avoid
dragging it over rough surfaces,
throwing it off the side of the delivery truck or
dropping it on to the ground
► Stack them upto 5’-8’ high and prevent from rolling due to
high wind or any other means
► Protect them from sunlight if they are to be stacked for
more than 6 months by a light colored opaque cover with
provisions for air circulation
► The discoloration means that the impact strength is
reduced
► At very low temp they become stiffer and brittle
► Store solvent cement in tightly sealed containers away
from excessive heat
17. Pipe joining
► Wipe the entire circumference of
the pipe and the socket
► Rub them lightly with sand paper
► Apply a thin layer of solvent cement
with cloth, sponge, glove or brush
to the outside surface of pipe and
Temperature Minimum Set
inside the sucket Range °C Time
► Then push the pipe end into the 15 to 40 30 minutes
socket and hold for a minute
5 to 15 1 hour
► Put it into the trench after the -5 to 5 2 hour
minimum set time
18. Laying of pipes
► Demonstrating the
villagers about joining
pipes.
► Demarcation of outlet
points.
► Using pipe fittings
properly.
19. Pipe installation
► Bed material should be
free of large stones
(>1.5”), hard lumps
and debris
► Goal should be to
provide firm, stable
and uniform support
for the pipe
► Trench width = 16-24”
+ pipe dia
20. Covering the trench
► Covering the trench only
with soil as far as
possible.
► Avoiding direct contact of
any hard substance with
the pipe.
► Avoiding loose packing
around the pipe.
► Avoiding exposure to
sunlight for the pipes.
► Checking erosion of pipe
line as far as possible.
21. Unfolding Stage-2
► On time availability of pipes was a problem.
► The construction process was uneven and behind
schedule because of internal conflicts among the villagers.
► Inter village conflicts had to be resolved. Positive role by
Rural Volunteer/s
► This year temperature was very high so, people needed
constant motivation to maintain the pace of work.
► Rebates under NREGS also affected pace of
implementation of DBI
22. Unfolding
continued
continued
► One type of intake structure were tried
1) tank to divert the water after siltation.
► Pipe joining was a big challenge because of the uneven
terrain.
► Regularizing village level committee meeting was not
possible in all the villages given the pace of
implementation, hence we took responsibility for executing
it, direct interaction with villagers with us monitoring sites
every alternate day,
23. Major Outcomes of Stage 2
►Development of confidence in the
feasibility of implementation by self without
external input both at the community and
team level
►Technical feasibility proved with water
being discharged @ 15-20 litres per second
►Emergence of atleast 4-5 youth (para-
workers) from the community who played
an important role in implementation and
monitoring the project
► Scope for convergence between NREGS
and DBI i.e. implementation costs from
NREGS and material costs from the project
in order to expand project.
25. It includes:
► Construction of structures for domestic use.
► Training people for improved agricultural practices.
► Making good quality seeds, fertilizer & pesticides available
to the farmers.
► Making improved agricultural implements available to
farmers
26. Unfolding Stage 3
► Tanks and other infrastructure for domestic utility yet to be completed
► Contact established with MPUAT
► Assistance sought from KVK Udaipur and GMKS Udaipur
► Training organised for 20 farmers from DBI sites at KVK with resource
persons from MPUAT
► Exposure visit and training for 150 farmers on improved agriculture
practices
► Breeder seed of Pratap III distributed (50 k.gs.) to 10 farmers
► Improved variety of Wheat seed (Raj 3765 & GW 273), 5 tons and 150
k.gs. Gram seed (Dahod yellow) provided to 150 farmers
27. Major Outcomes - Stage 3
► Better understanding developed
on how to assist farmers better
in improving productivity
Seeds of right quality to be
made available in time
Better handholding required
to ensure demonstration is
done effectively
Need to identify resource
persons/ agencies who will
provide the necessary
training and support to
farmers
29. It includes…….
► Documentation of experiences.
► Transferring total control of developed system over to the
community for future maintenance.
30. Unfolding Stage-4
► Documentation and data storing was a continuous
process.
► We are yet to develop systems for total handover of
entire system, would involve the following:
Strengthening of farmer group for each system
Understanding existing system of water distribution and
applying same/similar principles and norms for new system
This would include development of payment for water use
which would also go towards maintenance and upkeep of
system
31. MAJOR LEARNINGS
► Community should completely take charge for
implementation.
► Making the people to believe on the success of such
project was a difficult task.
► Every village has different dynamics so varied strategy
has to be taken at different stages in different village.
► In spite of good rapport and perfect exposure villagers
will not move unless their internal conflicts are resolved.
32. Continue………
► Need of such scheme is very high it is felt as crop
productivity in region is very low, little water is available for
critical irrigation and therefore project is important to
ensure food security and even incomes
► Maximum benefit is to women who now get water near the
village for domestic use, because it is far more useful than
the defunct tube well of the village.
33. OVERALL IMPROVEMENTS DURING THE
PROJECT
► Integration among the Village:
The village has developed a feelings integrity and resolved a
political issue.
► Technical Skills:
The resident also developed techniques for laying & joining
pipes. Identifying similar sites at different places. Though they
cant use dumpy level so efficiently but can act as a bare foot
engineer.
► Information and Awareness :
the village level committee is now a platform for
information sharing.
► Change in living: people are now ready to take double crop
and the schemes also addressed their demand for water in
most scarce time of the year.
