J. Background:
Although  Ethiopia  has abundant water resources potential,  its utilization  far both  drinking  and  irrigation  purpose has been Limited.
Oi the estimated 3 million hectares o{ land suitable {or large
scale irrigation, only a little more than 3% is utilized.
The situation is not much different far small and medium scale irrigation schemes. In fact, todate no survey is undertaken to
determine the potential on small/medium scale irrigation scheme, though there is a high interest in developing these scale far they are assumed as a remdy to relax the faodgrain requirements.
The main reasons far this slow development in the faeld o^ irrigations , inter alia, are lack ofi trained manpower coupled with financial resources. However, the priority o( government to enhance irrigation
in- the peasant agriculture has encouraged that excuting authorities give due consideratcon to the faeld. The programme in here are proposed fa r such consideration.

3.     pAQQAamme Objective:
3.1.       Development Objective:
The pAlme development objective o£ the pAogAamme Zs the development o^ land and wateA AesouAces Zn the ButajlAa aAea. The soZl sUAvey conducted ZndZcates that the soZls ts good

The objectZve Zs to ZncAease cAop pAoducZion by pAoducdng twZce a yeaA thAOugh the ZntAoducZng o£ ZAAZgatZon scheme. The aAea beZng, oveA populated, the ZntAoducZZon o^ ZAAZgatZon would tedurie the land holding system.
3.2.       Immediate bbje-c.ti.ve.:
3.2.1. Phase I
The immediate objective the programme is to provide
an adequate supply o£ irrigation water through the construction °6 a dam and its appertunant structures to develop ZOO ha. 0($ irrigable land <cn pha^c. I by gravity.3
3.2.2.     Pha*e II
By intAoducing a pumped iAAigation scheme faom the iame touAce {AueAvoiA} anotheA 2300 ha. can be brought
andeA iAAlgated agAicultuAe.
4.    The PAoject:
4.1.        Location:
The pAopoied iAAigation project i* located apAoximately 25km. we*t
ofi limy, on the main limy-ButajiAa Aoad, a* ihoui in FiguAe 1.
4.2.      The RuouAce*:
4.2.1.       WateA RuouAce*
The mean annual Aunofifi ^4,om the catchment aAea o£ 435 iqkmr ii estimated to be 15 M m’ o£ u/atCA. To itoAe thi* volume
uiateA the fall supply level o{ the AeteAvoiA Mould be about 4m. only.
Thi6 cleaAly indicate* that the fate i* an ideal place fa>A the comtAuction o£ dam.
4.2.2.        Land
The oveAall agAicuttuAal land in the aAea i* in the tune 3000 ha, HoweveA, faom the available wateA only *ome
2500 ha can be bAought undeA iAAigation -ie the 200 ha. by gAavity and the balance by meani o($ pumped icJieme.4
A reconnalsance level soil
0|$ -the. area Is available and
the     report     concluded     that     it     would     appear     that     the.     soils     ^rom     project     area are suitable £or irrigation.
5.      Activities
The anticipated actcv-cl-ces consist o£ detailed hydrological analysis, subsurface investigation, detailed design both the- headworks and the land development and construction.
The activities are schedule over a 3 - gears period.
6.    Outputs ;
6.1.        Phase I
In this programme of Phase I, about 200 ha. of land are to be
developed through the construction of 75M m  capacity dam having
J
a height of 4m. at the ML.
6.2. Phase II
Ulth the high possibility of power line linking Butajira with llway, a pumped scheme could reasonable sought as a phase II . In the event of the development a relatively cheap electric power should be available to develop 2300 ha.
The alternative development option would be to install a mini-hydro station to utllrze pari of the water stored^ to pump some water
to the project area. Using this techniques, the area under Irrigation would reduce substantially and is estimated to be in the order of 500 ha.5
7.     Input*:
7.1.        Extennal Input*
*    Equipment fan lnve*tlgatlon, de*lgn and
con*tnuctlve will be. *upplled
*    Equipment fan con*tnuctlon will have a *ufaeclent nange and ample flexibility to adopt the con*tnuctlon of dam and Innlgatlon pnoject.
*    A££ expendable Item* and pen*onnel co*t*
1* to be bonne by the flnancen.
8.     Pnoject Co*t:
8.1. Pha*e I
8.1.1.         The dam
The co*t the dam con*tnuctlon 1* e*tlmated
to be linn 5 million.
8.1.2.         Land Development:
To develop the 200 ha. of land about linn 2 million I* nequlned.
8.1.3.     lnve*tlgatlon & Ve*lgn
To puncha*e the lnve*tlgatlo>] equipment £on. geothechnlcal punpo*e an e*tlmated value of linn 1 million 1* nequlned.
The total pnoject co*t In pha*e I 1* about linn 6 million.b
Here -the. development cost per hectare would appear on the.
high side (Rdvi 40,000/ha}. However, this cost also
■include the cost otf the headwonk which would be used at a
later stage, phase II.
9.       Beneficiaries :
Under   phase   I,   about   400   heads   of   families   can   be   engaged   on   the scheme.
Since the area Is a good producer O($ sorghum, maize and wheat the Introduction Irrigation would bring a substantial
raise In yield. Futher, crops like pepper would generate cash Income.V*fap PROJECT ETH/82/OO8
