Authorities in Argentina's Chaco province have received four bids for the 235mn-peso (US$58mn) Puerto Lavalle-Juan José Castelli pipeline.
Bids were presented by Supercemento; Sye Construcciones; Cosugas; and a group composed of firms Esuco, San Andres Riva, Martinez and De La Fuente.
The bids will be evaluated over the next 45 days, under IDB supervision, the provincial government said in a release.
The 63km pipeline will stretch from the Bermejo river to city Castelli, with capacity to transport up to 278l/s. Other works include building a channel reaching Fortín Lavalle, a treatment plant with capacity to treat 1,000m3/h, and a pumping station in Castelli.
The work is being financed by IDB under its Norte Grande water infrastructure initiative, and is expected to wrap up in 30 months.
The project falls under Chaco's general water program, which aims to build 12-14 pipelines that will quadruple water capacity in the province to 25,000m3/h by 2014, boosting coverage to 93%.
