Chile's public works ministry (MOP) expects a consultancy for construction of the Livilcar reservoir in northernmost region XV to be completed by August, according to regional director Guillermo Beretta.
Local firm Miguel Nenadovich y Compañia is carrying out the project, which involves defining the total cost of the reservoir, currently estimated at 35bn pesos (US$71.7mn).
Work includes studies measuring rock and soil quality in the planned site for the reservoir in the Azapa valley, some 70km east of regional capital Arica, MOP reported on its website.
The regional government is financing the 1.69bn-peso consultancy, which also entails completing final designs for the 8Mm3 reservoir.
MOP will launch a tender this year to complete an EIA for the project, Beretta added.
