SCOPE OF WORK 1. The Main Drain 1 (MD1) has a normal drainage flow of 1.4 m /s and hence a potential for providing irrigation water t£o the extent df 1.4 m /s. The alignment of MD1 is such that with a cross-regulator and a head regulator, the drainage water can be diverted at point A shown on the Index map at Appendix 1, with a level high enough to feed the eastern branch of the Angelele Pasture Irrigation canal at point B. The structures and canal that have to be investigated, designed and estimated are as follows: (i) A cross-regulator across MD1 and a head regulator for the offtaking canal at A in the Index map. (ii) An outfall structure negotiating the water level at B of the Index-map. (iii) A contour canal with associated culverts for roads and drainage crossings from A to B in the Index-map for an approximate length of 10 km. 2. The above suggested work shall provide irrigation water almost free of cost to the Angelele Pasture Irrigation system. However, in certain short periods, when the salinity of MD1 shall be excessive, restrictions may have to be imposed on this gravity flow irrigation Water of MD1. The salinity of pumped water from the Awash shall be 0.4 mScm’1 whereas the capacity of the canal is 3m3/s. The allowable upper limit of salinity of good irrigation water is 0.7 mScm’ . Hence, if the total flow is 3m3/s and contribution of MD1 water is 1.40 m3/s, then the allowable salinity of MD1 can be upto 1.04 mScm-1. -1 1As shown in Table 1, to 5 the actual observed salinity of MDl is well within this limit of 1.04 mScm'1 for majority of the observations and can be safely used. The situation may marginally change on development of ADP II. When MDl water shall be augmented with surface water by run off from the rainfall or from extra rejection flow from the canal system of the Amibara Irrigation Project, the flow of MDl will be more than the normal flow arrived at a surface drainage contribution of 0.15 1/s/ha and 0.2 1/s/ha from sub surface flow. It may also be possible to augument the flow in MDl by having the rejection flows of the AIP system deliberately increased. The 5 years drainage flow of MDl is 5.5 m’/sec and discharges upto this can be safely carried by MDl. during the higher flow in MDl above the normal flow. Hence, the overall supplementing irrigation water may go upto 3m /s through the link canal. J This will cause considerable saving in the pumping cost of the Angelele Pasture Irrigation Project. During non-irrigation season of AIP, the irrigation water of the AIP can be fully diverted to Angelele Pasture Irrigation system and the pumping of the water shall not be needed. It is true that due to the accumulated salinity of the secondary salination leached suddenly to the sub-surface drain, the salinity of MDl could go above 1.04 mscm'1 for a snort period, for which effective monitoring of MDl water at offtake point shall have to ensured. This will help in not diverting MDl water when • the salinity of the water is high, bay above 1.04 mscm . The contour canal AB taking off from MDl is aligned along the eastern edge of the Amibara Extension area (area G) where -2 1irrigation is not yet developed. This area can be 3 conveniently commanded by the contour canal AB so far as ground slope is concerned. Thus this canal can be an alternative means of providing irrigation to this area of about 1,570 ha, the irrigation water requirement of which roughly corresponds to the normal drainage flow of MD1 of about 1.4m /s. However, the water of MD1 could be saline at times to such an extent that it shall not be fit to be used for irrigation unless mixed with less saline water. Hence, the option to mix the contour canal water with the pumped water of the Angelele Pasture Irrigation Project may have to be eventually considered. The area G may then be commanded by a canal system using the mixed water. This possibility of irrigation of the area G that is the Amibara Extension area could be considered at the next phase of the proposed supplementary study. The present study would be limited to the benefit of supplementing gravity flow of 1.4m /s to 3.0 m /s to the eastern branch of the Angelele Pasture pump canal system. 7. It needs to review the following points under the proposed study: (•i) What would be the duration of the normal flow of drainage water in MD1 and what shall be the dependable discharge. (ii) What extra discharge of the canal system of AIP can be safely surplussed into MD1 to augment its flow. Whether this‘saving can be adequate to serve the western command of Angelele Pasture Irrigation without any additional pumping facilities. 3 3 -3(iii) Whether there is any danger of silting up of MD1 due to more than envisaged rejection canal flow at (ii) above, which shall contain more silt. (iv) What will be the economic benefit of replacing pumped irrigation of Angelele Pasture Irrigation ' System vis-a-vis the capital cost of MD1 diversion and whether the cost versus benefit gives a favourable return on the investment.
