The project was cofinanced by a grant from the United Kingdom. The credit closing date was extended once, by two years, to June 30, 1983. Instead of a further one-year extension requested by the Borrover, the books vere kept open to allow disbursements against eligible expenditures until December 31, 1983. The final disbursement was made in March 1984 and the undisbursed credit balance of US$775,862.07 (15.5Z of the credit amount) was cancelled on April 23, 1984. The PCR is based on a review of IDA records and a draft completion report prepared by the Borrower (Irrigation Department, June 1984). Following a reviev of the PCR by OED staff, it was decided not to audit the project and the PCR was sent to the Borrower and the cofinancier for comment in September 1985. Comments received have been appended to the report. Hovever, as sustainability of benefits is a challenge faced by the project, it vould be useful if the project could be selected for an impact evaluation a fev years from now.  SRI LOUK TANI IRRIGTION NODERNIZ&TIOS PROJECT Credit 666-CE Basic Data Sheet KWE PROJECT DATA Appraisal Actual or Colum 2 as m 1stimate Current Estimate Column I (1) (2) (3) Total Project Cost (US$ willion) 23.0 / 16.66 2 72 Credit Azount (US million) 5.0 4.22 84 Cofinancing usS$ million) United Kingdom (ODA) 6.0 4.54 3/ 76 Date of Physical Components Completed 12/31/80 12/31/a3 Proportion then Completed (Z) 100 99 Economic Rate of Return (2) 23 15 65 Institutional Performance God Fair Agroeconomic Performance OGod 4/ Number of Direct Beneficiaries 79,000 >l 79,000 5/ 100 CUMUAfTIVE DISBIURSENENTS FY77 FY78 FY79 FY80 FY81 FY82 FY83 FY84 Appraisal Estimate (USS million) 0.5 2.0 3.2 4.2 5.0 - - - Actual (USS aillion) - 0.06 0.45 0.63 2.08 3.11 3.84 4.22 Actual as I of Appraisal - 3 14 15 42 62 77 84 Date of Final Disbursement: Marcb 28, 1984 PROJECT DATES Original Plan Revisions Actual Identification Report 05/17/74 Negotiations 05176 Board Approval 11/30/76 Credit Signing 01/12/77 Credit Effectiveness 03/14/77 04/18/77 6/ 04/12/77 Credit Closing 06/30/81 06/30/83 06/30/83 ij Excluding US$7.0 million duties and taxes. _f Net of duties and taxes. 3J Including US$0.69 million technical assistance provided under regular cooperation program. i/ As yet undetermined. / About 10,500 families; average family size 7.5 persons. 6/ Second revision.  SRI LIIJDA TAiK IRUIaTIO XODN URIZATIOU PROJECT Credit 666-CE BUaic Data Sheet (Page 2) MISSION DATA Sent Month/ No. of Mandays Specializations Performance Types of Mission by Year Persons in Field Renresented 1/ Rating 21 Trend 31 Problems y Identification FAO/CP 02-03/74 3 75 IS, A, E Preparation FAO/CP 06-07/74 3 + 2 112 IZ, A, E, 20 Preparation f FAO/CP 11-12/74 3 + 1 74 IE, A, 2E Preparation
