obra civil principalmente es la longitud de la
conduction.
En las mini-centrales o aquellas en las que se trata
de aprovechamientos con obras de ingenieria civil
sumamente slr;?ples y grupos de fabricacidn estan-
darizados, 10s costos bajan relativamente en algo;
bAsicamente la obra con&a de una toma simple, un
canal de conduction, tanque de presion conventional,
tuberia de presidn y casa de m&quinas, o pequeno
reservorio de carga para las turbinas tipo bulbo. Los

These costs result in an installed kW value
amounting to US$1,192; 1,466; 1,920; 2,200 and
2,700 respectively, which indicate a higher cost
for the civil works as the capacity of the plant
drops. In addition, the item that principally in-
creases the cost of the civil works Is the length
of the canal.
The costs are somewhat lower in the case of
mini-powerplants, or those that utilize very sim-
ple civil engineering works and standardized
manufacture groups. Basically, the works consist
