of derivering thzt fuel. Xo equivalent costs are associated<br />
with a well equipped with a 3and pump.<br />
The mast significant e:exsnt of t his total is the cost of<br />
fuel used for punping, being a?proximateXy 75% and 60% of the<br />
total in the Bay Region and Central Range respectively. The<br />
average annual fuel cost for each wcLZ site of $1,322 is based<br />
upon consumption of 3,396 iirexs at a current cost of USS0.39<br />
per 1 iter,<br />
Accurate data on f ~ei s~pplied tc well sites is scarce.<br />
Appendix 4.4.5 shows the reported value of fuel delivered to<br />
pre-project weli sires in the Bay Region during 1984. The<br />
figures available are for the three months of the Jilaal dry<br />
season, January to Karch, am3 for the whole year, 1984. Though<br />
the number 02 cases in Ikis saaple i s not sufficient to allow<br />
firm conclusions to be drawn. a linear regression suggests that<br />
these are reliable figures. It is assumed that for the three<br />
months of the Zilaal season the puzps are operated every day for<br />
90 days. Based upon the fuel consunption for a full year , it<br />
can be assued t%at che pumps are operated, on average, for<br />
eight months of each year.<br />
The fuel consumption rate of a diesel pump is obtained from<br />
the following Eom.ula (?ape, 1982, p. 19) :-<br />
C = 0.002635 x D x V x P,<br />
%here:<br />
C = Operating costs - to be determined for 1 hour of operation<br />
D = Depth of we31 - ~ssumed to be 90 n.<br />
V = Volume of wzter req- ired - known - 12 cm/haur<br />
P = Pxice of diesel f$/ltr) $0.39<br />
Therefore cost = SC. 69 per hour,<br />
representing 1*77 litres of fuel per hour.<br />
From Appendix 4.2.5, the average for the three months<br />
supply, Sh.9,364, costhg at :haz time approximately Sh.8 per<br />
lirer, represents l.172 liters. If the puxp is used every day<br />
for 90 days, t -~ls<br />
represents 33 liters per day. At 1.77 liters<br />
per kour, %his neans the p~:mp is used far 8 hours each day.<br />
There appears to be corsiderabfe variation about this nean.<br />
Bowever, the datz is ccnsidexed reliable enough for program<br />
costing purposes.<br />
