PURNA IRRIGATION PROJECT, STATE OF MAHARASHTRA

SUMMARY

i. Among the agricultural projects submitted by the Government ofIndia to the I.D.A. Mission in August 1961, the Purna Irrigation Projectwas selected for appraisal. A second mission made an appraisal of it inFebruary 1962.

i . TnnrThe nipojet. woild prnovride relbizh1 wate-r sunnlv for the irriga-tion of 152,000 acres of land now dependent on rainfall for crops. The+tn+.l tcst of' +.them oe inclu^;Ang n 15s°° T7T)r poMJpln iS Ts. :!680million. The main crops would be grain sorghum, cotton, sugar cane, rice,wheant, fTrit and vegetables.

ve ~The estimated total cost, fs. 168.2 million, includes espe±idituresof Rs. 38.4 million prior to April 1, 1961 (start of Indials Third 5-YearPlan) aIrU.d Rs. 4*L. li'hioII init.erest during the Tnird Plan period. Tne eUbi-mated cost of co.mpleting the project during the Third Plan (by April 1, 196(6)is RsQ0 125.6 million. Tnis inciudes Rs. 19.5 million expended during thefirst year of the Third Plan, a 23 per cent contingency provision on uncom-pleted works and interest during construction on Third Plan expenditures,

vi. The financing required would be the Third rlan expenditures ofRs. 125.0 million (Rs. 125.6 million less Rs. 0.6 million previouslyfinanced). The State of IvIaharashtra would provide 40 per cent of thefinancing from its budget and 60 per cent would be advanced by the Govern-ment of india at 4 per cent interest. It is proposed that the I.D.A. credi';Kto the Government of India be US$13.0 million, which is about half of thecost of completing the project.

vii. Soils in the project area range from heavy clay loams to denseclays with permeabilities varying from moderate to very poor. Sub-surfacedrainage facilities are not being constructed; consequently, sustainedirrigation of project lands depends on the successful administration of awater control program. Such a program would be established, but the rislkinvolved in the development of a project with inherent difficulties shouldbe recognized.

- ii -

viii. The project, given efficient management and sufficient technicalknow-how, would serve a useful role in the economy of India and should beself-liquidating at 4 per cent interest in about 36 years. The projectwould be constructed bv the Irrigation and Power Department of Maharashtrawhich would also be responsible for operation and maintenance of the irriga-tion faei1ities They are exnerienced and canable. The noaer plant w^ouldbe rented and operated by the State Electricity Board.

ix. The gross farm benefit/investment ratio would be about 44 per cent.Allowf.ing for a 10=year development period, t.h.e net beef+t/inxra_+,mnt ratiowould be about 114 per cent.

x, The project wiould be suitable for an I.DkA. credit of US$13.0mil"lion.

3. The Purna project was started by the former Indian States ofMyderabad and Bombay in 1955 and, after revision, was finally sanctionedby the Central Government in 1959. Reorganization of the States in 1960placed the project area entirely in M!aharashtra, which was establishedihen Bombay State was divided into the new States of Maharashtra and Guja-rat. Some financing was provided by the State and Central Governmentsduring India's Second 5-Year Plan which ended March 31, 1961. It is pro-posed to complete the project during the Third 5-Year Plan (April 1961 -March 1965).

L. Mlaharashtra, which includes in addition to part of the formerState of Pombay a small portion which was formerly a part of HyderabadState, has an area of about 76 million acres and a population of about 32million. There are about L0 million acres under cultivation, of which30.4 million acres produce food grains, about half of vhich is grain sor-ghum. The other important food crops are rice, grown on 3 million acres,and wheat, grown on 2.2 million acres. The principal non-food crop iscotton, which is grovn on approximately 6.3 million acres. At presentthere are about 2.4 million acres irrigated in the State, of which aboutone half is irrigated from wells and the balance from canals.

III. THE PROJECT AREA

A. General

5. The irrigable area of the project, consisting of 152,000 acres.is situated in Parbhani and Nanded Districts, in the Eastern part ofMaharashtra State. Principal towns in the area are Basmat and Nander. Amain line me-ter-gauged railroa serv the area with one hranch line bi-secting the project. All-weather roads are limited but there, is adequateaces t_.VV K- farm ove eona Vroads nn trals

6. Practica'Lly all the land in the project area is under cultivationwith less than 3 per cent under irrigation from wells. Yields from the dry-farmed areas are verv low but production from the areas irrigated show grocdprom-ise for significant increases in crop yields under irrigation.

7. Land holdings in the project area average about 20 acres of culti-vable land. Generally; the holding is farmed by the owner. State law pro-hibi'ts ownership of more than 30 acres of irrigated land.

8. The climate of the project area is tropical, characterized bylong. dry perinds from November thrnugh Mavy fnllowed by the monsonn seasnn,June to October. The average annual rainfall is 32 inches, with about 8%fall:ing in the monnson season. Daily temperatumre commonly exceed 100°F.during the period March to June, with an annual mean daily maximum close toS0°F. 1 Te arnual mfln~ean dai5w strlm ereaveo bu 70°F. r.iakes thearea suita'ble for a great variety of crops.

The calculated averageannual runoff is 47.832 nilion cubic feelt (1,098,000 acre feet) (seeA.nnex 1). There is a wide variation from year to year with a loW runoffof >,050 mcf (1920) and a high of 122,011 mcf. (1916).

10. Present and estimated future upstream uses total 1,700 mcf. Theproject is planned on a 75%o reliable yield. This yield is obtained bychoosing an annual runoff which would be equalled or exceeded in 75% of theyears. Deducting upstream use, this figure is 26,100 mcf, or 600,000 acrefeet for Yeldari inflow. Similarly, the inflow to Sidheshwar below Yeldariis h3,700 acre feet. The planned water supply is thus 643,700 acre feet mintuslosses in evaporation and transportation.

11. The average annual combined inflow is 1,098,000 acre feet at Yel-dari plus 79,000 acre feet at Sidheshwar or a total of 1,177,000 acre feet.The twater supply comes entirely from rainfall and the quality of water forirrigation is very good.

12. There is space in Yeldari Reservoir for holdover storage and theplan of opere ion contemplates a normal holdover of about 190,000 acre feet(Annex 2). This would be utilized to augment the irrigation releases inyears of low precipitation and runoff (one in four). Irrigation requirementr

(para25)could be met in all but the extreme dry years (2 in 57 years). Duringthese extreme years, irrigation would suffer shortages of as much as 50%.

generally the soil, topographic and drainage characteristics of the areawhich will finally- be se"lected asO theU prJe.UCt%t' irrigable cLreage, sn0_the essential soil surveys are not scheduled for completion until Octo-ber 1762e.

.LL4. U1 genelaL., UIIhe s0o±is are resiuual, deri-vUe prminri'lary fromibasalt formations in the area. Very limited areas of light textured soils,sandy loam to loafib, exist on the higher lying ridges and ill LLIC extrem..elower end of the project, At most, these latter soils will probably notrepresent more than about 2% to 3% of the irrigable area.

i5. 0 LnUThe DUlk of the irrigab'le area - roughly 90% - will be composedof soils, black in color, with the surface textures ranging from heavy clayloams to dense clays. These soils appear to be iairly nign in organic mat-ter, calcareous, and to have a good wqater retention capacity. They occupyareas with gently undulating to comparatively flat topography. Surfacedrainage i.s generaLlly satisfactory but internal drainage varies from moderateto very poor. This soil, except for small isolated spots, is free from harm-ful accumtulations of salt.

16. The balance of the irrigable area, 7 or 8%, will be made up of areddish-brown, very heavy clay. Surface soils are hard and cloddy when dryand sticky and impervious when wet. Subsoils are platy in structure andnearly impermeable. This soil type is generally found along the drainagecourses. The soils of this type to be selected for inclusion in the irri-gable area will be those with the best position, topography and surfacedrainage characteristics. Many areas composed of this type of soil are lyingin the less desirable positions and are carrying large concentrations cftotal salts, together with high exchangeable sodium.

17. Topography of the area is gently undulating. Some nearly flatareas do occur on the ridges between the many natural drainage courses.Field layoLts may be performed in such a manner as to require a minimum ofleveling for irrigation. Bundin, of fields is practiced in this localityand some contour irrigation will likelv develop on lands with greater slopes.

18. Surface drainage is adequately taken care of by the marn naturalwater courses. In general, subsoils of project lands vary in permeabilit-yfrom restricted to very poor. In keeping with usual Indian practice forplanning irrigaticn projects, drainage facilities are not being constructedas part of the project works. This is based on the premise that the addi-tiornal cost of drainage works would not be justified on most irrigationprofiects in India. Consequently, sub-surface drainage must be controlledby strict water management.

19c The soils in the project area with their restricted permeabilityare highly susqcepttible to waterlogginp and to the accunulation of toxicquantities of soluble salts. A furthler factor compounding the problem isthe 2lck of'f s drainaveo facilities; the cost cf which would beprohibi-tivee.

D. Principal Crops

21. Under present conditions, agriculture in the area is limited_ ~~~~_ _ _ s___ r___ __ _ 1 __ t_.__ _- --. L__ S: - i_ 1_.0_almost enuirely to dry farming. Tlhe unsatisLLaor:wy annul UJ-SiribUUtiULo o

rainlfall precludes the production of many crops and materially affects theyie:lds of those that are grown. Also, the soils are difficult to manageunder improper mo:isture conditions, thus resulting in higher productioncosts. Despite these handicaps the farms appear to be well managed bu-tyieLds and net returns are very low.

22. Grain sorghum is the principal crop produced under present con-ditions. About 97,000 acres, or 55% of tne cropped land, is devoted tothis crop (see Amlex 3). It withstands the long drought periods well andhas become firmly established as a leading crop for both human and live-stock consumption. Oilseeds, primarily safflower, are grown on about25,000 acres each year. Wheat, gram and cotton are also produced, ave:^-aging about 21,000 acres, 16,000 acres, and 12,000 acres per year respec-tively. A relatively small acreage of rice - about 6,000 acres - is g.owneach year. A minor amount of double cropping - about 25,000 acres - isattempted each year. The principal crops used for this purpose are grnmand oilseeds.

23. The future cropping pattern (Annex 4) is exnected to be quitedifferent from the pattern now followed and no doubt will have severalcrops new to the area. The yields of crops now grown are so low that withirrigation very significant increases will be possible. Although grainlsorghlm will probably remain the principal crop, with an expected area ofabout 61,000 acres annually, the yield should be more than tripled. It isexpected that the wheat acreage will be decreased while the cotton acreagewill be slightly increased but cotton yields should be improved at leastsixfold. Consideration would be given to further increasing the cottQn acreagewhenever feasible. It is proposed that a considerable part of the cottonacreage will be devoted to the production of several new promising selec-tions of long-staple cotton. New crop introductions to the area willincLude sugar cane and fruit. The sugar cane crop is expected to averageabout 19,000 acres annually and, as the soils are well suited to this crop,the yields should be good. Much of the sugar cane will be for local con-sunmption as gur. It is expected that the principal fruits will be bananasand citrus. If the areas to be used for fruit production are carefullyselected and the plantings are properly managed, yields should be good.Vegetables and ch:illies will make up the balance of the 152.000 acreswhich it is expected will be irrigated each year. Second crops, consist-ing of gram, oilseeds. vegetables and green manure crons; totaling about67,,000 acres a year will be grown without additional irrigation. Thesecrons wLill rely on the remaini ng fertilizer and soil m.oist.ure from theprevious crop, together with whatever amount of rainfall that might beavailablen Although the vielrd of the second crop will be low the netretu-rns in most years will justify the practice.

24.. Tn fnreAasting the expected acreage and yields for the futurecropping pattern consideration was given to the present cropping pattern,the soils, the farmer and his many problern of manaemrment. credit andmarketing and to production on other projects.

tiorn of 22 inches. This is nearly adequate during this period but must, besupplemented by irrigatio-n during years of less than average rainfall. Thecropping pattern contemplates irrigation approximately 12 months of theyear bDut the critical period occurs between September 25-October 15.During this 20-day period the rains - if any occur - are very light, thterice is maturing and there is an overlap oI other crops. Tne total re-quirement is h8,30O acre feet for the 20 days. Allowing a factor of 70%efficient utilization in the field and 20% loss in the canals and dis-tributaries the canal headgate capacity requirement is about 2,000 cusec.This is the maximum requirement and the canal would be built to meet it.The irrigation requirement of the canal headgate is 480,000 acre feet peryear.

F. Services to Farmers

26. IMaharashtra State has an ambitious program for farmer assistance.The program is divided into three parts: (1) the usual type of extensionprogram under the Department of Agriculture; (2) a project demonstrationfarrm; and (3) a Scheme for Intensive Cultivation of Food Crops. The exten-sion program has for many years been operating in Nanded and Parbhani D)is-tricts. The program consists of soil surveys and analyses to determinefertility status, guidance in cropping plans and crop varieties, fertilizerdemonstrations and, recently, arrangements for irrigation demonstrationshave been made with 30 farmers in the area who have irrigation pumps. Thesesmall demonstrations are widely dispersed throughout the proposed irrigablearea and are being used in an educational program for the prospective irri-gatcors under the project. A demonstration farm, consisting of 215 acrEs,is locatecl in the upper end of the project near Golegaon. The purpose ofthis farm is to make experiments, trials and demonstrations of crop varie-ties, fertilizers and irrigation practices. Work is underway on the farmat present and irrigation water should be available in the fall of 1963:.

27, The Scheme for Intensive Cultivation of Food Crops is a State-wide program for certain selected areas. One such selection has been inThe Purna project., The program envisages the intensive cultivation of acomrpact b-Lock of 20,000 acres. The land -:ould be farmed by the owner ortenant but under the direct supervision of an agricultural officer incharge of the hlock. The agricultural officer would be assisted bc tenagricultu al assistants from the State Agricultural Service and rep:-eselnta-t.ives of t-he o-operative DnPrtmnent.

The extension staff previouslymentioned would also have an important role in the program and would, atthe end cf the first five-year period, assume the future operation of theScheme for Intensive Cultivation of Food. The Scheme, if carried out asplanned;. wsuiild materiallv inerease the services now available to farmersthrough the Extension Department.

IV. THE FROJECT

A e

29,* - ~ ~ The prpjec- is -the irrigation of 1_52,3 0o acCr along tjie ±e.t U

side of the Purna River Valley. The main works include a composite damat Yeldari with EL reservoir of 704,UUU acre feet gross capacity a re-.regu-lating reservoir of 200,000 acre feet behind another composite dam atSidheshwar, about 5u miles of concrete, or masonry, lined main canal and25( miles of distributaries to irrigate 152,000 acres. About 3Cg of theproject works was completed during the Second Plan period and would notbe included for financing under the proposed credit.

B. Yeldari Dam

30, The Yeldari Dam is to be a composite structure with a 168-foothigh gravity section masonry dan in the Purna River channel, The founda-tion in the channel is good basaltic rock, but this is partially disinte-grcated at higher elevations on the abutments. A central overflow spillwaysection provides for ten 411 x 38t Taintor gates and a design discharge of384,000 cusec. A short spillway apron with a curved jump lip would dischargeagainst a firm rock slope in the river channel.

31. Steel penstocks embedded in the dam to the left of the spil]waylead to the powerhouse at the downstream toe of the dam. Two 7,500-12Tgenierators are to be installed initially with provision for a third unitlater. Power genierated would go directly into the Maharashtra State Elec-tricity Board grid.

-7-

32. Three 6'3" x 8' sluices to the right of the spillway section candischarge 3,000 cusec for release to by-pass the powTer plant. Earth em-bankment sections would overlap the masonry structures at each end andwould extend 14,90C) feet along the saddle at the left flank and 4,500 feetat the right flank. The height varies from 20 feet to 68 feet and thesections vary with foundation conditions.

33. Yeldari Reservoir would have a gross capacity of 784,000 acrefeet, of which 120,000 acre feet are reserved for silt and 190,000 acrefeet for holdover cyclical storage to make up deficiencies in years of lowinflow.

3h. The maxi-mum flood of record was calculated to be 350,000 CUSeCin 1958. Yeldari spillway is designed for a flood of 384,000 cusec atfull] reservoir levrel. iYaximum flood level discharge would be 410,000CUSeC With 11.5 ft. of freeboard below the top of the dam. The dischargewould be about 500.000 cusec if flood level reached 5 feet above the maxi-mum, This would be a maximum safe level with freeboard of 6.5 feet. ThesniLlwav orovisions are considered adeouate.

C. Power

35. The Yeldari Hydroelectric Plant at the base of Yeldari Dam wouldhawe tuo 7,500 Kn Kwnits initially with the pnwerhouse structure- npnstockand gates installed now for the future addition of a third unit. The Yel-dri~-- PpResem-oir wonm1lr ha-rm (650n_onn aerer feet. nf livrie .qtravp ahvew t+he pn-stock intakes and the average net head on the turbines would be 94 fee-t.Mn-riminm hei.ad wo iibe rhi 19'5 feet and mrnirirmin 66 feet.- Pele2 for i-rrii ntion and power would be scheduled by the Irrigation Department to meet re-nuiremyents for flood control, irriation and power, in that order ofpriority.

36. The power plant would be operated by the Maharashtra State E:Lec-tri-ity Board xhic-h would take all energy ge erAt +into t- gA tt+ +1tbus bar. The Electricity Board, during the Third Plan, is to build 132 KV,66 Ky and 1 i nd distribuion sysems in the srroundingdistricts, interconnecting coal-fired steam generating stations at Paras(60NAATr) n-nrl (ArhMATuJaL.JCl (60a .J) w.i+vh S.da.r .= J I a.r ct Bor wo'.

Two feethigher flood level would discharge 4550,000 cusec with ireeboard oI 6 feet.Flood moderation, cdue to Yeldari and Sidheshwar storage above normal fullreservoir water level was not considered in the design and provides additionalmargin of safety. The spillway provisions are considered adequate.

E. Irrigation Canals

iLO. The main irrigation canal on the left of the Purna River wouldihave headwsorks at the left end of the left flank embankment of Sidhesh-warDam. An approach channel is provided in the reservoir to the headgatestructure. Three 15' x 16' vertical lift gates would control dischargeto the 2,000 cusec capacity concrete-lined main canal.

JL. The first 10 miles of the canal are located in foothills withsome major cross-drainage channels, The 36-mile long, concrete and masonrylinecl main canal and major distributaries vwould serve most of the irrigablelands by gravity. However, it would be uneconomical to serve all the landIn this genieral area as it is undulating and cut by small drainage chanrels.in acddition, the main canal is to be extended to a total length of 50 milesto economically serve the balance of the lands, bringing the total irrigablearea to 152,000 acres.

42. Major distributaries (85 miles) would also be partially concrete-lined to minimize water loss in the areas where the subsoil is disintegratedand porous. Other distributaries (165 miles) would provide irrigationservice to meet individual owJners.

F. Construction Schedule

43. Under the original schedule of the State Irrigation Departmentthe project was to be completed in 1967 during the first year of the Fourth5-Year Plan. There is no physical obstacle to completing the project duringthe Third Plan. The acceleration of the project is desirable and it has beenag-reed during negotiations that funds would be made available to enable theproject to be completed by MIarch 1966, the end of the Third Plan period.

44.o The Yeldari and Sidheshwar Dams are about 8G% completed and canale:eavration is about 2G05 completed in the first 10 miles. Land classificatic,nis ornly partially completed and the lands to be served by the 14-mnile maincaiAl eYN+.nsion ha-ve not yet b determineedn It is expected 1;hat t,:i -be completed during the fall of 1962.

G. Estimated Costs

46. rThe total cost of the Purna project, including interest duringconstruction, is esitimated at Rs. 1608.2 million (Annex 7).

141. DxpeLldi-ures O- Rs. 890,000 were made by the States of nyer-bad ar,dBombay during the First 5-Year Plan and further expenditures of Rs. 36.'3million were made (during the Second 5-Year Plan. Interest during constructionon funds loaned by the Central Government would increase the cost to a totalof Rs. 37.5 million during the Second Plan period (to April 1, 1961).

480. Details of expenditures to date were provided by State authoritiesand future estimated expenditures are in line with these. They have beencompared with costs on similar work in India and are realistic. A contingencyitem equal to 23 p(er cent of estimated costs of the uncompleted works has beenincluded and is considered adequate.

O9. Allocation of costs for the power plant includes all direct powercosts plus 15 per cent of Yeldari Dam costs. The total power allocation isRs. 25 million, including interest during construction. This allocationallo'ws a reasonable return to power and the balance of the cost - Rs. 1143.2million - has been assigned to irrigation. Estimated expenditures duringthe "hird 5-Year Plan are Rs. 119.5 million, excluding interest. Includinginterest during the construction period the estimated cost would be Rs. 125.0million. The expenditure schedule would be approximately as follows:

H. Finance

50. The Purna project was started by the States of Hyderabad andBombay during Indiats First 5-Year Plan. It was sanctioned and given somefinancing by the Central Government during the Second 5-Year Plan. Theproject also received foreign exchange credit through a Technical Co-operationIlission advance for purchase of construction equipment during the Second Planperiod.

51. A total amount of Rs. 157.2 million was sanctioned and at present,Rs. 89.4 million is allocated for the project in the Third Plan. This wasbased on estimates made in 1959 and allowJing for completion of the projeetsometime in 1967. Costs have risen since then and an additional cortribu-

53. Foreign exchange required for project completion is Rs. 12.3r(UQ2,600,0O0 rounded) for materials and equipment not available

in India. This includes spare parts, tools, workshops, hoists, cranes,gates, turbines, generators, shafTs, switch gear and related components.

54. Third Plan financing for completion by April 19066 is RlS 125.Umillion. This is the estimated cost of Rs. 125.6 million minus Rs. 60C,000prevriously financed. Forty per cent would be provided from the MaharashtraState budget and the balance would be advanced by the Central Government at%7o interest. Time for repayment of Central Government advances has not beenestablished for this project. However, since this project comes under theterms of loans of the iiviiscellaneous Development Loan Fund Schernesi", theterms of this scheme would apply, viz., repayment in 7 to 15 equal annualinstallments after an appropriate grace period.

.55. It is proposed that the IDA credit wiould cover about 50% of thecosts incurred during the Third Plan, amounting to Rs. 62.5 million(US013.0 raillion rounded).

V. ORGANIZATION AND IANAGEViENT

A. Construction

56. The Irrigation and Power Department of Maharashtra State has gereralcharge of the project. Planning and design were done by the Public WorksDepaLrtment of Bombay State prior to re-organization of the States. Essen-tially the same personnel are now working on the project. The Central Water ar:dPower Conmnission (C.Ti.P.C.) is the consultant. The construction is under theChief Engineer, Irrigation, of the Irrigation and Power Department. Depart-mental forces are doing most of the earthwork construction. Yeldari andSidheshwar masonry dams are being built under unit price contracts by Indiancontractors. The contracts were awarded after advertising locally in Indiaand competitive bidding, Gates, hoists, and power plant equipment Nould besupplied and installed under separate contracts. The canals and distribu-taries would be built under departmental supervision, using small unit pricecontracts, to be awarded after bidding, for short sections of the work,

57. There are resident executive engineers in charge cf the work atYeldari. Sidheshwar and on the canals, each havine arDronriate oireaniza-tions for supervision of the work. They are q'lalifie' and experi-ei-t:ed

60. The power plant equipment would be purchased under internationalbidding in which Indian manufacturers might participate. Specifications,tender documents and the analysis of bids would be subject to review byC.W.P.C. These same documents would be submitted to IDA prior to issuanceand award of contract.

B. Operation and Maintenance

61. Operation and maintenance of the irrigation facilities of thePurna project will be under the administrative and technical control ofthe Department of Irrigation and Power, Government of Maharashtra, withoffices in Bomdbay. For purposes of administering irrigation projects theState is divided into irrigation circles. The Purna project comes withinthe Deccan Irrigation Circle, Aurangabad Division, with a SuperintendingEngineer in charge, with offices in iwurangabad. Project headquarters,with an Executive Engineer in charge, will be located in Basmat. Basmatis centrally located in the irrigable area of the project and direct com-mnunications will be available between Sidheshwar and Yeldari Dams.

62. Plans for operating and maintaining the project were discussedwith the Superintending Engineer and his staff, all of whom have had someexperience on operating projects. The Superintending Engineer proposesto use, to the extent necessary, experienced operating personnel from otherprojectsin the Circle. The plans for establishment of an operating organi-zation and. the procurement of the necessary equipment for operation andmaintenance are satisfactory. The Yeldari power plant would be operatedand maintained by the Electricity Board, with the Irrigation Departmentscheduling water releases (see para. 35).

63. Details of project facilities to be operated and maintained areshown in Annex 8. Operation and maintenance cost estimates are based ondata furnished by project personnel and on observations and comparisonswith other projects in India. These estimates are as follows:

A. Water Rates and Betterment Levy

66. The current water charges in the areas served by the Deccan Canalsin.cUud boUthi water rates andu al li uig n cess as establis1eU WY bSate

Government, Resolutions. The combined rates, which are higher than in mostInLIal Stabes, vaI-y widely fromn a high of ns. 170 per acre per year forsugar cane - which requires water throughout most of the year - to a lowof Rs. 9 for the kharif (wet) season crops grown in the monsoon seasonfrom June to October.

67. The State of Maharashtra would undertake to recover operation andmairtenance costs and all the monies invested by iP¶aharashtra in the Purnaproject by levying appropriate water rates and other charges on land benefit--ing from the project and by a rental charge for the power plant.

68. The Stat,e is currently considering the revision of its presentsystem of irrigation charges and has recently appointed a State IrrigationCommission for this purpose. According to draft recommendations of thisCommission, water rates would be levied on the basis of assessed gross inconeper acre and would range from 6 per cent up to a maximum of 12 per cent ofgross income. In addition, a consolidated betterment charge, equivalent to20 per cent of the water rate, ijould be imposed. On this basis, a combinedcharge of about Rs. 52 per acre (covering water rate and betterment charge)would be appropriate under conditions of the Purna project at full develop-ment; this charge per acre, though higher than that levied on irrigationfarmers in most other Indian States, would not be high in relation to thecustomary level of' charges in this State. Rs. 52 per acre would be equiva-lent, to about 9.5g of gross income per acre or 11 per cent of expectedaverage increase in gross value of production.

69. As in other new irrigation projects in India, concessional rateswould be charged the water users during the first three years as an incentivetowards more rapid use of the new facilities. Some irrigation would startas early as 1963, and it is assumed that full irrigation revenues will beavailable three years after completion of the project in 1966.

B. Revenues From Power

70. The Electricity Board would pay an annual rental for the powerplarnt sufficient to recover the capital investment in 25 years at 4 per centinterest, or about, Rs. 1.6 million (see Annex 9).

C. Operating Costs and Repayment

71, Xvith water and other charges averaging Rs. 52 per acre. annualirrigation revenues would amount to Rs. 7.9 million (Annex 9). Directoperation and maintenance costs are estimated at Rs. 6Oq.00o and there wvru0be a, surplus, before depreciation and interest of Rs. 7.3 million. Thiswould be sufficient to amortize the irrigation allocatinn of t.he investrLrcrrr.(Rs. 143.2 mill'Lon) at 4 per cent interest in about 4' years.

- 14 -

72. The project revenues from power would be the annual rental on tilepower facilities of about Rs. 1.6 million to be paid by the Electricity Board.The combined project revenues from power and irrigation, less costs of irri-gation operation and maintenance, would be sufficient to amortize the totalinvestment at 4 per cent interest in about 36 years. This is considerablyshorter than the useful life of the project which is assessed at about 60years.

73. Approximate operating results of the Purna power plant are shownin the final section of Annex 9. The firm power (available in 95 per centbof the year) rate of Rs. 0,04 (USIP0.008h) compares favorably with coal-firedsteam generation costs. Secondaly power rate of Rs. 0.03 (US$0.0063) isabout the same as fuel costs for steam generation in the area. The powerwould all go into the Maharashtra Electricity Board grid for the area, whiLchwould have 120NW of steam capacity. Revenues from sales of power are expecterlto amount to Rs. 1.9:1 million annually. Deducting operation and maintenancecosts of about Rs. 170,000 and the annual rental charge, Rs. 1.6 million,there should be an annual surplus of about Rs. lhO,000.

VII. BENEFITS AiND JUSTIFICATION

7h. Benefits from the Purna proiect will be from the increase inagricultural production with irrigation and from the hydroelectric powerto be loroduced at YeLdari Dam. Irrigation is the principal purpose of theproject and Rs. 143.2 million of the costs has been assigned to irrigation.The costs assigned to power include the snecific costs for the nower faci-lities plus 15 per cent of the cost of Yeldari Dam (see para. 49). The totalof these costs is approximately Rs. 2< millison

75 Based on e mPret.- c-ron vields nnd nprsnt nripcs the -nnn-1 v-l-ip

of future production at full development has been estimated at Rs. 81X.5million (Annex )h). This woulld he an incr e rof' ahui+.

78. Applying the very approAim.ate estimates of net benefit per acrebefore water charges to the full area of irrigable land (152,000 acres) thebotal net benefits would be abo-ut Rs. *40.U null±±on. DieUuctinLg the anulual0 & M costs of Rs. 61X5,000 the order of magnitude of annual net benefitswould be about Rs. 4(0 million at the time of full development (1976).Allowing for a 10-year development period and discounting the annual benefitsover the lif-etime of the project - 60 years - the net benefit/investment rat:owould be about lh per cent.

79. These estimates are necessarily approximate but they indicate thatthe proposed Purna irrigation project is justified by the expected increasein returns from crop production.

VIII CONCLUSIONS AND RECOIMENDATIONS

80. Considering the nature of the soils in the project area with theattendant drainage and salinity problems, it must be recognized that theproject; is not without risk. hater management would have to be carefullyhandlecl to avoid serious waterlogging and/or accumulation of undesirableamounts of salts. Given efficient management and sufficient technicalknowJ-how the project should be successful and would provide considerablebenefits to the farmers in the area. It would also contribute significantlyto the production of food in a part of India which at present has a deficiencicT.

81. The project, construction and operation would be under the directionof the Ministry of Irrigation and Power of Maharashtra State, which isexperienced and capable. Because of the special nature of the soil problemsa constultant would be retained to advise on the design and operation of awater control program and to make annual visits of inspection.

82. 1Uith the proposed water rates and betterment levy the irrigationproject, would be financially sound and self-liquidating at ! per cent interestin about L0 years. Combined irrigation and power revenues would anortize theproject, at a per cent, interest in about 36 vears. The economic benefits voulI4justify the investment.

83. The project would be suitable for an IDA credit of US$13.0 million,representing about 50 per cent of the financing required for completion.
