Nine international companies submitted bids to the authority for sustainable usage of lake Amatitlán (Amsa) for geological and topographical studies on the US$30mn "mega project" to clean up Guatemala's lake Amatitlán.
"We will open the proposals today [Jan.25] and probably select a winner next week," Amsa executive director Édgar Zamora told BNamericas.
According to the bidding rules, the winning bidder will have 15 days to begin working on the studies and eight weeks to finish the project. Project construction is slated to begin by June this year.
The project aims to build a 12km, 44m-wide canal with biological filters and waste traps on the Villalobos river to reduce the 1.5Mt/y of sediment and 10t of waste and wastewater discharges the river carries to lake Amatitlán.
Amsa authorities are testing a new FMF water filtration system from Spain for the project, which is scheduled to wrap up by end-2007.
The Inter-American Development Bank (IDB) will fund about 80% of the project, with the rest of the funds coming from the government.
