Project Location and Description:
The proposed project is located in
the village Ghulam Sarwar Khan Kalay,
which is situated at a distance of
21 km from Mardan towards southwest.
The villagers are permanent residents
of this area. Their main language
is pushto. Main occupations of the
villager are agriculture, live stock
rearing and some of them also works
as daily wagers. The villagers enjoy
the facility of linked road and electricity,
having govt. primary school for boys.
There is also one primary school for
boys and one for girls as well established
by HDF.
Almost 70% of the community is directly
linked with agriculture, uses primitive
method in agriculture fields. Watercourses
in the village are almost unlined.
The watercourses that are to be lined
consist of two portions, one of which
is 790 feet long and another is of
600 feet length. The main corps of
the area is, sugarcane, Sugar beat,
wheat and vegetable.
Project Identification:
The inhabitant of the village formed
a DO on date 01/09/1999. With 16 membership
having Rs. 94,000/- savings up till
now. Most of the villagers have their
own agriculture lands, irrigated by
kaccha watercourses. As unlined watercourse
reduces its capacity to provide required
quantity of water to the fields. Large
quantity of water is wasted due to
unnecessary flow at the points where
the banks of watercourse are badly
destroyed by heavy rainwater floods.
Because of which water is not available
at the tail end of the fields, which
greatly effects production of corps
from the fields.
The community observed their prioritized
need, as lining of the watercourse.
In this regard they submitted a resolution
to HDF requesting both technical and
financial assistance for the provision
of irrigation scheme. The field staff
of HDF (Field Engineer, Social Organizers)
conducted technical and social surveys
with the concerned CO and found the
scheme feasible.
The Objective of the Project:
The main objectives of the project
are:
- To prevent seepage loss and thus
more area can be irrigated.
- To decrease workload on farmers.
- To minimize the social disputes
arising over shortage and theft
of water in peak cropping days.
- To prevent silting in the watercourse.
- To provide smooth surface, to
increase velocity of flow.
- To provide more stable banks
to reduce erosion and wastage of
water through banks.
- To reduce maintenance cost of
watercourse.
- To reduce weed growth.
- To assure economical water distribution.
- It is also an important anti
water logging measure.
DESIGN AND COST ESTIMATE:
Design:
 A
detail survey of the area was conducted
along with the CO members and it was
observed that a kaccha channel exists
in which at the head end slope is
maximum, and at tail a new watercourse
is supposed at one of the turning
point of the kaccha watercourse which
will join another watercourse which
is also unlined by the combination
of these two courses more water will
be available to the fields nearby,
so the community wants to construct
a new watercourse and to line the
existing one from junction point to
the end.
Beyond the junction point this channel
has blocked at several sections due
to sliding of earth banks, large quantity
of water is wasted due to seepage
at different sections and also due
to out flow at the points where the
course is badly damaged. Keeping in
view all of these aspects, it is proposed
that lining of channel should be provided
to achieve the main objectives of
the project as discussed above.
The designed length of channel is
proposed as 1390 feet, and the section
designed are shown in the working
drawings.
The capacity of watercourse has been
designed by taking into account water
requirements of the crops in the area
and then using Manning formula the
designed data has been provided as
follows.

Cost Estimate:
Total construction cost of the project
would be Rs 2,86,795/- with PPAF contribution
of Rs 2,23,700/- and community contribution
of Rs 63,095/-. The community will
provide the land free of cost. The
cost estimate is based on local markets
rates. Skilled person with necessary
tools would be hired from outside
the village. The community itself
would provide unskilled labour required.
The details are attached as annexure-C.
Maintenance Cost:
Maintenance cost is Rs 8,604/- per
annum at 3% of the total cost. The
CO will open a separate account in
the bank before the completion of
the project. The annual maintenance
cost will be collected by the maintenance
committee from community and will
deposit in the bank. The money will
be spent on the maintenance of the
project and maintenance committee
will keep record of all expenditure.
ENVIRONMENTAL ASSESSMENT:
As the project is proposed to upgrade
the economical condition of the community
and to provide a sustainable irrigation
scheme, therefore all of the environmental
aspects are studied and found no negative
impact of the project on environment
and as such no mitigation measures
are required.
Qualitative Benefits:
Impact on Assets:
Agriculture land is the most sustainable
asset of farmers. With this project
land productivity would be increased
by 40% and the farmers would be able
to get 100% cropping intensity from
farms. With such high productivity
this asset of land will become more
valuable.
Impact on food:
With proper availability of water
for irrigation, all type of crops
can be cultivated over this land.
Thus food availability will become
more secured.
Impact on livestock:
With more cultivation and agriculture
production, more food will be available
for livestock and more production
can be got from livestock.
Cash income:
With secured water for irrigation,
cash crops can be cultivated resulting
in cash income for farmers.
Impact on health:
Wheat shortage has been a serious
problem of villagers for the last
few years. With this project, production
would be increased and is expected
to impact nutrition standards of the
villagers. Similarly health improvement
of livestock will impact live stock
bi-products and ultimately villager’s
nutrition standards would be improved.
