Value Profiling : DAMS
Pressure Point: more ponds can be formed to store the water from the catchments ,since
the land availability is less to create such bhandharas
Chock Point: the height of the dams cannot be increased because the farms are next to the
dams and due to excess water supply the crops will get damaged.The dams cannot be in
ampole amount since of land scarcity.
Function
To store water for a longer period
of time so that farmers can
cultivate crops throughout the
year without facing any drought
problems.
Experience
In summers they face lot of
problems related to percolation of
water.
Dams existed from the era of
1870s
Limits
Dams are drying out because of
bad weather conditions .
Challenge
Percolation of water with increase
in population of the villages .
Height Increase
Stones/Cement :-Stones are the basicraw material requiredfor constructing the
dams.
Farms:-Water which is storedin dams is used as airrigation purpose for
the cultivations ofcrops.
Labour:- Labour isrequired for theconstruction ofdams.
Catchments:- Rainwater is stored intodams with the help of
these catchments

Value Profiling : CANALS
.
Pressure Point: No maintenance head under govenrment budget, people are not aware
about the benefits
Chock Point:- A permanent canal cannot being built because of various issues of land, water
and political scenario
Function
The rain water which is hit by the
catchments and directed towards
the river is being supplied into
the farms of various villages by
building the canals and giving
them diversification through
various gate channels.
Experience
The canals are usually dig by the
farmers before 3 months of rainy
season. The canal water is being
given to each village as per
rotation of 7 days. the metal gateis used as a channel to diversify
the water.
Limits
Per farmer a canal is not possible
because of limitation of the areas.
Challenge
No proper association is taking
into account the canal
infrastructure
Labour:- Digging workof the canals isundertaken by thefarmers themselves byappropriate tools.
Crops:- most ofthe crops receivewater by thesecanals
WaterDiversification:-Water from riveris diverted towater theneighboring
farms
Farms:- waterfrom canals isused to water
farms.

VALUE PROFILING : Roads and Houses
Welingkar
.
Pressure Point: Village area remains neglected as more focus is upon
developing near by industrial area and SEZ
Function
Houses solve the purpose of
providing shelter to the villagers and
their animals which are their source
of income.
Experience
There are very rare concrete
structures, rest are houses made of
brick walls and mud walls covered
with bamboo rooftops
Limits: budget allocation by govt.,
availability of labour
Challenge:- Because of the major
area of the village is covered by
farms villagers are finding difficult to
setup new houses.
Brick Houses:-Most of the houses
are made of bricks
and covered with
clay or mud.
Roads are semiconstructed and are
in descent condition

Value Profiling :Rivers
.River water is used for
cultivation
Pressure Point: no NRM (Natural Resource Management) system incorporated till date
Chock Point: no perennial source of water, dependence on rain
Function:-
To cater to the basic needs of the
farmers as well as water the farms.
Experience
The village suffers drought between
the span of January to May.
Water inside the river dries out .
Limits:- River water is not
accessible to all the 20 villages
around.
Challenge:- Water percolation is
the greatest challenge .
Source:-Source isfrom therain water
Catchment:- It isbasically a drain areafor rain water. Water is
drained down into thevillages in the form ofriver.
Bandharas: tostop and divergewater to differentcanals attachedat variouslocations

VALUE PROFILING: WELLS
Function:-
To cater to the basic
needs of the farmers as
well as water the farms.
Experience
The village suffers drought
between the span of
January to May.
Water inside the wells
dries out .
Limits:- number of wells
Challenge:- More wells
are dug because of the
decrease in the water
table.
EMPTY WELL:-Empty wells are theoutcomes of reductionin the water table
Too many number of villages is
a threat to water table, its
difficult to maintain the same
Chock point: no regulatory body to keep a
check in excessive digging of wells in a
certain locality

Scenario 1:Seasonal Employment for Women in the drought period.
Welingkar
.
Value point: Employment generation, way of earning, way of resources utilization
Seasonal Employment:
In Sinnar region people rely
largely on rain water .The
cultivation cycle is of 6 months
starting from June/July to
December/jan and can beextended up to month of feb-
mar depending upon the
availibity of water.
When rain doesnt fall in plenty
amount the water table
becomes low and there is no
enough water for the cultivation
of crops
During this period ,the women of
the house can utilize the time by
doing 3-4 months of seasonal
employment'. Like doing origami,
stone carving ,or working in fields
or making home made pickles.
This will not only make them self
employed but will serve a
purpose of earning.
Weaving bags, carpets, mats willbe an a good options since manyof them are good in sewing andthis can be sold in near by macromarkets
The skills required to make aBidi is very similar to Origami ,so this type of the hand madeproducts can be exhibitedand sold in the govt.
emporium and private shops
In the Sinnar area there was a lot of whitestone available. So it can be crushed tomake rangoli or can be carved in various
small sculptures which can be sold in highend gift shops.

Scenario2 : Effective Irrigation Techniques
.
Chock Pint: the higher cost of diesel energy may be a factor mitigating against
this technology.
Drip irrigation is already in use,
we propose to introduce Linear
irrigation system measures 1 km
across, with two arms each
extending 500 m, traversing 2,5
km, and giving total irrigationcoverage of 250 ha. The company
says that the technology saves
water, reduces labour input, is
able to produce the highest crop
yields at relatively low capital
cost, is flexible and offers greater
water management capabilities,
with a 95% uniform water
distribution over the crop. Linear
systems are fed through a central,
or side, channel, which is cheaper
and has a lower energy demand
than pressurised pipe systems.
The larger systems are diesel
driven, so there is no reliance on
electricity, which is erratic in
many parts of INDIA
A great deal of focus isbeing placed onoptimising existing systems
through bettermanagement in an effortto increase efficiency andsave costs without theneed for large capitalinvestment,
Farmers who switched from sprinkler irrigation to drip
systems (above) have cut their water use by 30-60%
Treadle pumps
A simple, inexpensivehuman-powered waterpump to irrigate crops. This
technology would helpSinnar farmers if it could beadapted to local conditionsand manufactured locally.

Scenario 3:- Government
.
Commitments of the government:-
1) Maintenance and efficient operation and modernisation where necessary of irrigationsystem in the Command Area.
2) Development and maintenance of the main and subsidiary drainage system in the
command Area.
3) Conducting soil survey from time to time and modifying most suitable cropping pattern in
the command Area.
4) Ensuring efficient maintenance of the fixed channels and field drains within the command
area.5) Prescribing and enforcing an appropriate system of distribution and regulation of water
supply through the command Area.
6) Implementation of policies of the Government in respect of the intensive development of
the command
7) Long term solution of proposing a huge dam project with hydroelectricity power plant in
order to store the water from catchments and various other sources, this will be done with
the help of collaboration with private sector company (source : confidential )
Chock Point: Govt. Officer Irrigation dept. : We dont want to spend on
maintenance of such a system(traditional British times Canal and bandhara
System) which is temporary and provides water during rainfall, we are looking
forward to large projects which can be a long term solution.

Scenario 4: Guntha farming
.
The 5 ghunthe farming is that in which instead of cultivating 1 crop in
whole land. the farm is divided in equivalent 5 different areas. In each
area separate crop is cultivated. So the lands 1 bhiga is 1/5 guntha.
40 ghuente-1 acre
20 ghute -1 bhiga
Its a good practice in time of water storage since itll earn around 1000/-
per day. so maximum propagation of such farming should be done

Scenario 6: Rain Water Harvesting programs
.
Rainfall is the mostunpredictable thing.most of the rain wateris being wasted andpasses throughdrainage and sewagegutters. there are two
ways for rain waterharvestingStorage of rainwateron surface for futureuse.Recharge to groundwater.
Storage of rainwater on surface forfuture use
Dams:percolation ofwater
Ponds: helps to store thewater in small areas ,unlikedams it is small and is totalindependent
Weir is a small
overflow dam used toalter the flowcharacteristics of ariver or stream

Scenario 5:Rain water harvesting: recharge of ground water
.
Chock Point: more area is required for if in case we are making rain water harvesting for
whole village.
Recharge toground water:WellsPits
Wells: the water can be stored but ifincase huge number of wells are
placed in one area, itll causewater table low.
the Rooftop collection of
rainwater can be done as thewater can be collected withthe help of catchment andthe water will be stored I bigcontainers, as a storagepurpose.
