Argentina's national water and sanitation board Enohsa has received three economic bids for the first stage of a project to overhaul Concepcion del Uruguay city's potable water system, budgeted at 52.3mn pesos (US$13.3mn).
The Eleprint and Ecopeneur group bid 48.5mn pesos, JCR offered 50.5mn pesos, and a consortium composed of Isolux, Pietroboni and Jose E Piton offered 51.3mn pesos, the Entre Rios government website reported.
Offers submitted by Alquimaq and Rovella Carranza failed to qualify for the tender, according to the report.
First-stage works include repairing the Uruguay river water intake and pumping system, expanding the potable water plant to treat 18,000m3/d, and installing storage and distribution tanks. The project will take about 18 months to complete.
A second phase will involve upgrading the city's potable water distribution system.
