Abstract

A study was conducted in the Directorate of Water Management, University of Agriculture Faisalabad, Pakistan during the year 2011. The objective was to compare the performance and cost of various alternatives for watercourse improvement. For this study three watercourses (5486-R, 114626-R and 116928- R) located at Shahkot distributory in Sheikhupura district were selected under different socio-economic conditions. The detail cost of material, labour, lining and earthen improvement of watercourses were calculated on annual basis. The average net return of water saving of higher cost improvement and lower cost improvement were compared. Average water flow rate at section A (head), B (middle) and C (tail) of water courses was calculated as 25, 22 and 19 lps, 61, 45 and 44 lps and 55, 47 and 38 lps for watercourse 5486-R, 114626-R and 116928-R, respectively. Average loss rate of water was calculated as 1.91, 3.08 and 2.51 lps per 100m length of watercourse. The annualized watercourse lining cost (annual initial cost of improvement + annual maintenance cost) of watercourse was found as Rs. 254, 245 and 216 per meter per year for 114626- R, 116928-R and 5486-R, respectively. The results revealed that lining is the best alternative for sustainable water savings as compared to earthen improvement and cleaning of watercourses. [ABSTRACT FROM AUTHOR]
