SHIRAPUR LIFT IRRIGATION SCHEME
TALUKA: MOHOL DISTRICT: SOLAPUR
CHAPTER I INTRODUCTION
1.0 General description of project Bhima River is one of the main left bank tributaries of the main Krishna
River. It originates at Bhima Shanker in Sahyadri ranges and flows from West to East till it joins River Krishna in Karnataka state.Total run of River Bhima crosses Pune and Solapur District. In Pune District near village Chas, taluka Rajgurunagar (Khed), Chaskaman dam is constructed across River Bhima and Bhima Project is constructed across River Bhima near village Ujjani, taluka Karmala. Some of major and medium projects completed and under construction are on the tributaries of Bhima River. Sina River is the main left bank tributary of the Bhima River. Sina River originates at Dongargaon Tal. Ahmednagar, Dist. Ahmednagar and flows from west to East through Ahmenagar and Solapur Districts till it join River Bhima at Takli, Tal. Akkalkot dist. Solapur near state boundary of Maharashtra and Karnataka States. Sina River in its upper reaches is tapped by various M.I. schemes and medium projects like Sina Nimgaon, Wangi etc. across River Sina, near village Awati, sina Kolegaon project is under construction. The area in upper reaches of this project is under construction. The area in upper reaches of this project gets benefit by fringe lifts only. Hence downstream area of this project is still un-irrigated.
1.1 Necessity of the project
Due to Sina Kolegaon project the flow of water in River Sina will effectively be restricted and run of River from this project site to any major confluence point will remain dry. From toposheet it is observed that no any major tributary is meeting to River Sina up to village Bhoire. At village Bhoire River Bhogawati meets River Sina & hence upstream run of River Sina from this confluence will remain practically dry in future, and no water resources will be available for the area on both banks of the River. As such there is consistent demand from this area to let down water from other sources, such as Ujjani storage, to Sina River for utilization on both the banks. The dry run of Sina River is curtailed by Mohol branch canal of Ujjani project at village Lamboti. It is also noticed that the area between Mohol branch and Wangira nalla, which meets river Sina at village Shirapur is also drought prone area. This area dose not has any irrigation facilities. Hence there is a long standing demand from this famine affected area for providing weir on river Sina through let out water from Bhima Sina link tunnel project, which will carry water from Bhima storage to Sina River. The identified command area
lies in North Solapur taluka of Solapur District i.e. geographically on East side of river. Rainfall in the area is scanty and is in the range of 500 mm to 600 mm (20” to 24”). The maximum rainfall is available in the months of Aug., Sept. etc. due to which some of rabbi crops are only possible. Deep and good fertile soil is available; crops with higher yield can be grown. The area proposed to be benefited by this project lies in N. Solapur & Mohol Taluka of Solapur District. This taluka is chronic scarcity area and the only means to improve the standard of living of the people in this area is to provide them irrigation facilities.at present there is irregular flow in Sina River due to scanty rainfall & Sina Kolegaon project. River Sina is tapped in its upper reaches by various projects. Moreover Sina Kolegaon, a major project near village Awati is under construction. It is proposed to utilize about 4.00 TMC of water by this project, to irrigate area by fringe lifts only and no water will be left down in the river. This will affect the down stream flow of river in future.
It is therefore necessary to provide water for irrigation on either bank of the river by one of the alternative source.
1.3 History of the project
There is a long standing demand for providing irrigation facilities to famine affected area of N. Solapur & Mohol talukas of Solapur District.KWDT has allotted 599 TMC of water from Krishna river to Maharashtra state to be utilized by 2000 A.D. to have full utilization of water allotted to Maharashtra by 2000 AD it was reviewed that how much water is going to be utilized from the completed & under construction projects. After reviewing it was seen that there is scope for expansion of water uses to achieve full utilization of water allotted to Maharashtra Accordingly most of these expansion schemes are being planned to serve the drought affected area considering available sources of water. Solapur District is chronically drought affected area. To serve the irrigation benefits to the scarcity areas a major Bhima Project has been constructed. KWDT award has restricted use on main stream of Bhima to 95 TMC during any water year. Accordingly after accounting for planned utilizations on main stream of Bhima, it was seen that about 6.60 TMC of water can still be utilized from Bhima River. Moreover it was noticed that about 30 5 of Kharif water is not being utilized though potential has been created under the project. Keeping in view these factors, about 13.6 TMC of water of Bhima project is proposed to be utilized through various L1 schemes. For details of availability of water and L1 scheme p1 vide Appendix No. v/2 & 3. Shirapur L1 scheme is one of those proposed scheme with water utilization of 1.73 TMC. Chief Engineer (Specified Projects) submitted a note showing broad details of proposed scheme to the Govt. on the basis of note Govt. directed to prepare detail project report of the proposed scheme vide latter No. 1095/(180/95)/ WRI dated 11/08/95. As per this note ICA of the said scheme was 6000 ha having water utilization as 1.4 TMC. Mean while Govt. directed to modify the scope of the scheme vide Marathi letter No. S95/3095/35-Mu.Ma.Sa.
(91/95) Ja.Sa.A. dated 23/02/96 up to 10000 ha of ICA. Hence command area of this scheme is finalized to 10000 ha having water utilization of 1.73 TMC. Layout of Shirapur Lift Irrigation Scheme is first decided on the basis of toposheet study to verify the feasibility of the scheme.
1.40Present proposal To join Bhima storage & Sina river it is proposed to construct a Bhima-Sina link
tunnel canal of 26.5 km length from Ujjani lake to provide irrigation benefits in Sina valley. In Sina valley there are three schemes to be served through Bhima-Sina link tunnel & same are as under
A) Bhima-Sina Lift Irrigation Scheme- by series of KT weirs for both banks of river Sina.
B) ShirapurLift Irrigation Scheme- to serve the area in North Solapur & Mohol taluka.
This tunnel will provide required quantum of water from Ujjani Lake to Sina River starting from village Kandar and ending at K.T. weir at Kave a Sina river. This will provide assured and adequate water supply to the above schemes. To provide irrigation facility to surroundings of Vadala, Vangi, Mothewadi, Chicholi, Karamba, Mardi & Nanaj etc. from North Solapur & Mohol taluka of Solapur KT weir on river Sina, which will be fed by letting out water from Bhima Sina link. It is proposed to give irrigation benefits to 10000 ha of area in North Solapur & Mohol taluka by lifting water from Shirapur KT weir. The Shirapur KT weir is fed by Bhima Sina link. It is proposed to lift water from river Sina @ Shirapur KT weir near village Shirapur in two stages. This include first lift of water with 4.03 km long rising main from RL 1430’ (436m) to 1589’ (484.5m) having static head of 159.08’ (48.5m). From delivery chamber of 9.63 km in length is proposed. At the end of main canal i.e. @ 9.63 km stage II lift is proposed near village Mothewadu. Stage II includes lifting water by 2.55 km long rising main from RL 1565’ (477.1m) to 1650’ (503 m) having a static head of 84.95’ (25.9 m). After second lift LBC of 4.70 km and RBC of 15.5 km is proposed.
1.5. Location of the project
The lift scheme is proposed on the river Sina at Shirapur KT weir, taluka Mohol, district Solapur. This weir is situated near Miraj – Solapur road. Village Shirapur is situated near taluka boundary of North Solapur and Mohol taluka.
Stage II lift is approachable from Shirapur– Solapur road. Geodetic location of the command area is as under.
Toposheet : 47 O-9,10,13,14 & 56 C- 1,2 Latitude : 17 – 48’ – 00 “ N Longitude : 75 – 43’ – 00” E
1.6 Access and roadway The proposed lifts are near village Shirapur taluka Mohol (for stage I) & Mothewadi
taluka North Solapur, dist. Solapur. The village Shirapur is approachable by Solapur – Miraj road. It is near about 40 km away from Slapur city. Command area of lift is crossed by Shirapur– Solapur road and Miraj – Solapur road.
1.7 General climate conditions The project is located in Solapur District of Maharashtra State. The temperature varies from minimum 10OC in winter to maximum 45OC in summer months. The rainfall in the command area is very low and having erratic and unreliable pattern. It varies from 500 mm to 600 m. 1.80 Command area It is proposed to provide irrigation benefits to 10,000 ha area by this lift scheme. GCA under this lift is 20,000 ha. Command area under this lift is situated at higher elevation of Sina River and is lies in villages Vadala to Kedgaon & Mardi. Very few nallas flowing towards the river Sina originate from this area. 1.8 Topography Command area of the scheme is almost flat and is having gentle slope towards the nalla/river. 1.9 Geology The main rock is basalt and top portion is weathered rock and end product of this weathered rock is soil which is good for cultivation and soil cover for vegetation is quite adequate in the command area There are no significant mineral deposits in the command area. The area is covered by medium brown/black and dry soil. 1.10 Population As per census book 1981 about 27874 people from 19 villages are likely to get benefited by this scheme. 1.11 Natural resources In this region agriculture is dependant upon rainfall which is insufficient and uncertain. Providing irrigation facility to grow two or more crops in this area, local nallas are the only source for water supply. However as these nallas have small catchment areas their yield is limited and they dry out very soon. Also the area proposed to be served is situated at higher elevation of Sina river
1.12 Infrastructure Being DP area there is no infrastructure development in the command area. However due to assured water supply & development of irrigation, infra structure development; including agro industries may be possible. The simulative effect of the above would result in improvement of living standard of the general masses of the area. 1.13 Socio economic aspect
There are no important industries in this command area except Taluka places. The main source of living hood in this area is agriculture. The command area lies in North Solapur taluka, which is famine affected area.
1.14 Stages of construction
The present scheme is proposed to be constructed in one stage only. It is planned to complete the scheme in a period of three years including pre construction years.
1.15 Stage of development It is planned to complete the construction of the project in a period of 3 years and development of irrigation potential will start from second year. 1.16 Interstate aspect
The entire command area falls in the Solapur district of Maharashtra State only. Hence,there is no interstate aspect so far as this scheme is concerned.
1.17 Cost and benefit of the scheme

CHAPTER V HYDROLOGY
5.1.0 Water availability
Bhima river is one of the major tributary of river Krishna and it joins Krishna in Andhra Pradesh state,. River Bhima is tapped by Chas – Kaman and Ujjani major projects as well as some M. I. project i.e. K.T> weirs U/S and D/S of Ujjani project. Bhima (Ujjani) is one of the major projects in Bhima valley, constructed across river Bhima near village Ujjani, in Madha taluka of Solapur district. KWDT has permitted to utilize 95 TMC of water on main stream of Bhima, it is seen that 6.6 TMC of water is still left to be used within this permitted limit of 95 TMC by KWDT. It is proposed to use this much quantum of water through the additional conveyance system planning of Bhima project. The present water use planning the Bhima project is as under:

CHAPTER VIII IRRIGATION PLANNING
8.1.0 Crop Pattern Considering present irrigation practice and water availability proposed crop pattern for Bhima Sina project is approved by Agriculture department, Pune Bhima Sina project and Shirapur L.I.S. both lies in Solapur district/ Climatic and geodetic conditions of both the scheme are nearly same. This crop pattern is suitable for Shirapur L.I.S. also. As such the same cropping pattern is proposed for planning of this scheme. The Crop pattern for this scheme is as below-
Sr. No. Name of crops Percentage 1. A) Two seasonal Chilies 3
3 B) Kharif 2. Jawari 10 3. Ground nut 25 4. Maize 2 5. Vegetables 10 6. Sunflower 10 7. Tur 10 Total 67 C) Rabbi 8. Hy. Jawari 15 9. Gram 5 10. Sunflower/Safflower 2 11. Vegetables 5 12. Rabbi Jawar (U.I.) 45 Total 72 Grand Total 142
8.3.0 Crop water requirement
As per the proposed cropping pattern fortnightly crop water requirement is worked out by modified Penman method. Gross irrigation requirement is
worked out considering conveyance efficiency at 75% & field application efficiency at 65%. For flow irrigation it is taken as 49% of net irrigation requirement. For the crops as per cropping pattern the water requirement is worked out by modified Penman method for different seasons initially for 1000 ha, considering transit efficiency of 49%for flow irrigation. Gross water requirement works out at 4.8877 Mcum/0.1726 TMC per 1000 ha. The gross water requirement for different seasons as below:
9.1.0 Command area development The gross command area of the project is 20000 ha. Out of that cultural command area is 20000 ha & irrigable command area of the scheme is 16000 ha. Command area lies in between Mohol branch canal of Ujjani system and district boundary of Solapur & Osmanabad & higher elevation of river Sina.
9.1.01 Climate The total command area lies in hot weather region having inadequate and scattered type rainfall in a range of 20” to 24”. The area is generally dry except in rainy season. The weather report says that a maximum temp. is 45 0 C in summer and minimum 10 0 C in winter season.
9.1.02 Irrigation projects There are no major and medium irrigation schemes in the command area of the N. Solapur taluka. Some minor irrigation schemes are in existence, but the area already under irrigation is not considered for this scheme.
9.1.03 Economic Aspect There are no industries or factories in the command area of project. The main resource of earning of the local population is agriculture, however due to insufficient and unreliable rainfall the agriculture is not economical.
9.1.04 Agro industries and banks There are some agro industries in the command area. After introduction of irrigation there is a large scope for agro industries especially because of well linked national highway and railway to Bombay and Pune and Solapur district places. Services of Indian Bank and District Co-operative banks are available at some places in command area.
9.1.05 Present agriculture practice Agriculture in command area is totally dependant upon rainfall. Farmers are using good quality of seeds; fertilizers etc. for agriculture and are practicing dry agriculture practices. Irrigation is therefore demand and needs to be provided as eagerly as possible.
9.1.06 Increase in employment At present there is no source of employment. However after introduction of irrigation, irrigation facilities, there will be change in socio economic condition of the region resulting in increase of the employment opportunities.
9.1.07 Soil survey in the command area Soil survey of the proposed command area is being carried out by Director, Irrigation Research & Development, Pune. It is being taken up in 1996 -97 programme. However during the survey it is seen that soil in the proposed command area is deep seated with sufficient vegetation cover, fertile & will produce food grains with higher yields, if assured water is made available for irrigation.

CHAPTER XVII B.C RATIO AND FINANCIAL RETURNS
17.1 B.C Ratio and Financial returns Benefit cost ratio has been worked out with following data. A) Benefits of agricultural produce: i) The yield rates of agricultural produce for different existing and proposed crops are taken as per agricultural Department Circular for the year 1994-95. the benefits of crops per hector before and after introduction of irrigation are considered as per communicated by the deputy Director, agriculture Department’s circular and benefits of exiting crops which are not available in circular are worked out considering yield. ha at 50% of irrigation crop. ii) Expenses of seeds, manure and fodder etc. are considered as per Agriculture department’s circular. B) Annual cost of project:
I. Simple interest @ 10% on capital cost of the projects is considered. II. Energy charges of L.I. Scheme are taken as rate Rs. 300/HP.
III. Depreciation charges are considered 1% (excluding cost of rising main and pumping machinery)
IV. Depreciation of pumping system is taken 8.33% of pumping cost considering lift of pumping system as 12 years.
V. Depreciation of rising main is considered @ 3.33% of cost of rising main considering life of rising main as 30 years.
VI. Annual maintenance charges area taken @ Rs. 500/ha of CCA. VII. Maintenance charges are taken @ 1 %. 17.2 B.C. Ratio
The B.C. ratio of the scheme works out to 1.08. The cost per ha/acre of irrigable area works out to Rs. 90566/ha & 36519/ac.
17.3 Conclusion
1. The B.C. Ratio of the scheme works out to 1.08 which is attractive compared to limit of 1.0 prescribed for drought prone area.
2. The scheme will improve socio economic condition due to employment, small scale industries, poultry and other supplementary works of so far
scarcity affected area of Mohol and N. Solapur by providing irrigation facilities.
3. After commencement of this scheme drought relief measures will not be required in future resulting the indirect benefit towards the scheme.
4. Working cost of the scheme definitely increases year to year. As compared to this benefits of crops do not increase because those are fluctuating and depend upon demand & supply. Due to increase in food grain prices of some commodities are likely to shut down in future. This affects economics viability of the scheme. However green revolution is need of time. Water is precious, water is life, hence by all means we have to harness available water resources and use it probably where it is needed before 2000 A.D. So apart from B.C. ratio keeping in mind, all other indirect benefits etc. & to have social justice this scheme needs to be launched.
5. Flow irrigation is traditional method of irrigation. To have saying in water and increase in irrigation potential the beneficiaries need to be persuaded to use it by adopting modern technology of sprinkles / drip system. Initial cost of this may be more, but farmers will accept it, if it is strongly recommended and increase benefits are brought to the notice.
6. This scheme is part and partial of Ujjani project. Many Lift scheme are proposed through the planning of Ujjani project. Some of them are either economic or costlier even. However considering them all together composite Ujjani project should be considered.
7. The scheme is therefore recommended for approval. B.C. Ratio Calculation Sr. No.

GENERAL NOTE WITH REFERENCE TO REVISION OF PROJECT REPORT Introduction
The Shirapur Lift Irrigation was Administratively Approved by MKVDC
Pune vide Marathi lr.No. Shirapur/296/(146/96), PB-2 Dt.10/10/1996 for
Rs.9056.63 Lakhs. Rates adopted for the AAPR were as per sanctioned
DSR in the year 1995-96 & prevailing market rates for the itess which were
not included in the schedule of rates
As per revised project report 2010-11 the total cost of the scheme
comes Rs.24779.95 Lakhs
Present Status of the Scheme
From the date of Administrative Approval (i.e.10/10/96) till the deteline
of revision of Project Report i.e. Dt.30/07/2010 various component of the
scheme have been tackled. The works tackled so far are as follows-
A) Head works:- i) Preliminary investigation for the head works i.e. pump house, rising main
delivery chamber is completed.
ii) Pumping capacity, rising main details (No. of rows, dia thickness) also
finalized.
iii) Design of head works is monstly completed through the consultant.
iv) Detailed estimates on the basis of actual design received are framed &
these are sanctioned by Competent Authority.
v) Rising mains is almost completed.
B) Canal 1) Preliminary investigation & detailed alignment survey is completed & the
length of link canal, RBC Km.1 to 7 & LBC Km.1 to 4 is completed.
2) The Survey work of Km.5 to 16 of LBC (i.e. Kalman Extension) is
completed & the alignment is approved.
3) Command area survey is in progress.
4) Extension of LBC from Km.5 to 16 (Kalman extension) – Shri.Uttam
Prakash Khandare, MLA (Tal:North Solapur) requested in his letter to the
Chief Minister, Govt. of Maharashtra dated 09/12/1996 regarding extension
of LBC to irrigate the villages Gavadi Darphal, Kalman, Kauthali, Padsali
etc. in Noth Solapur Taluka Compared to project report provision, there is
reduction in command area of RBC, due to (1) Forest Area, (2) MIDC Area
(3) MI Tank Command, (4) Area which can not be brought under irrigation
due to growth of Industries & housings. Total deduction in area due to
above factors is 2087 Ha. to compensate this area LBC is extended from
Km.5 to 16 MKVDC has given Approval to this proposal of extension vide
marathi letter No.797/ (529/97) PB-5 dated 13/05/1998. Due to this
extension there will be no increase or decrease in the total ICA considered
in project report.
Necessity for Revision of Project Report 1 As stated earlier, AAPR was framed on the basis of rates for the year
1995-96 since from the date of A.A. period of 15 years have been passed.
In this period various works are undertaken & details of various
components have been finalized. Hence it is notice that Revision of the
project report is necessary. Various reasons for Revision of Project Report
can be summarized as below-
a) Broad & conceptual designs of the scheme have been finalized & important
parameter of lift scheme i.e. pumping capacity, No. of pumps, type of
pumps, rising main, No.of rows & their diameter, thickness etc. are
finalized. And after detailed design it is noticed that there are substantial
engineering modifications & cost of these components is likely to be
increased as compared to the provisions for the same in AAPR.
b) Regarding main head work components like inlet channel & forebay, pump
house, pipe laying, delivery chamber, it is noticed that there is considerable
Engineering modification which will definitely cause increase in cost of the
scheme.
c) In respect of canals, detailed estimates for surveyed portion which are
based on approved alignment, canal sections finalized, revealed that there
is considerable change in provision made AAPR & provisions need to be
revised.
d) Provisions in the AAPR for some of items e.g. cost of Mechanical, electrical
components etc. were based on either pro-rate basis or lump-sump basis.
Now detailed estimates for their items are ready which shares necessity
for revision of earlier provisions in AAPR.
e) Increase in the rates of various components including cost of land.
f) Total cost of sanctioned estimate has reached the total estimated cost of
the scheme, still number of components remains untackled.
g) In respect of canal it is necessary to incorporate number of canal structures
as per site requirement, similary there is also changes in rates of irrigation
benefits.
2 In view of the above points it becomes necessary to revise the project report
taking into account the details finalized so far, increase in the cost of the scheme
as well as increase in the benefits & arrive at the revised cost of the project.
Detaeline considered for revision of the project report- It is decided to revise the project report considering the rates for the year 2010-
11. Total cost of all subhead/ items under sub-head cost total in (i) Actual
expenditure & (ii) costg of balance work on the deteline of the revision is

Following method is adopted while revising the estimate-
1 Separate estimates are prepared for each sub-head under I-head works as
well as II-Main Canal & Branches.
2 Total estimated cost for each sub-head is worked out on the basis of actual
expenditure incurred upto 30/07/2010 & balance work as on Dt.01/08/2010.
3 In respect of important cimponents under I-Head works viz. Pump House,
Rising Main, Delivery chamber estimated cost considered in this revised
project report is as per the technically sanctioned estimate prepared on the
basis of approved design.
4 Mechanical components i.e. pumping machinery & allied equipments is
based on the basis of approved designe prepared by private consultant.
5 Electrical components- a) Power supply (33 K.V.) actual quotation received from M.S.E.B.
b) Estimates are prepared on the basis of detailed design received from
design consultant.

Canals:-
6.1 Lining : Length in which canal lining is proposed where Q > 100 cusecs.
6.2 Earth work : Estimates are divided in two parts i.e. surveyed length &
unsurveyed length. For surveyed portion the total estimated cost is worked
out canalwise i.e. link canal, LBC & RBC & it is on the basis of kilometer
sanctioned estimates.
For un-surved length of canal
a) Type estimate are enclosed for RBC & Link canal.
b) Cost/ Cunecs/ Km. is worked out on the basis of canal discharge in that
length & estimated cost.
c) On the basis of design discharge & length of reach cost is worked out on
the basis of cost/ Cumecs/ Km.
6.2.1
Structures-
a) F-RHT work: On the basis of estimated cost of some structures of which
detawise are finalized.
b) Bridges : Estimate is prepared for a bridge on the basis of detawise are
finalised.

Excess – Saving over the AAPR
1 There is about Rs.15723.32 Lacs excess 173.63% over the cost of project
as per AAPR under each major head i.e. Headwork & canals respectively
comparison of AA cost, split up of excess/ saving in to various categories
for each sub heads are given in excess saving statement.
2 Excess is mainly in C – Works of I - Head Works
Excess in C-Works of Head Work in respect of Pump House, rising Main
etc. is mainly due to structural engineering modifications during detailed
design.
Fesibility of Scheme
1 Calculating the benefit cost ratio on the basis of revised cost & benefits has
checked feasibility of the scheme. Benefit cost ratio is worked out on the
same basis that is followed in AAPR.
2 Following points need to be noted regarding BC Ratio calculation
1 Annual cost of the electrical energy is worked out taken in to account
current electgrical energy tariff.
2 Details regarding pre-project & post-project benefits for the year per
3 On revision of the project report BC Ratio works out to 1.65
4 This L.I.Schene is from the fringe of Ujjani reservoir. In total 7 L.I.Schenes
are in progress & one L.I.Sche is proposed from (Bhima) Ujjani Project
Reservoir. Combined B.C.Ratio of these all projects is more than one.
