Mexico's national water authority Conagua plans to tender the construction of a third pipeline on the Cutzamala potable water system before the end of 2011, according to the authority's director of potable water, drainage and sanitation, Antonio Gutiérrez.
The project requires an estimated 4.5bn pesos (US$349mn). Work could begin by end-2011 and is due to wrap up by 2013, local daily Milenio reported.
Conagua recently completed work to repair line 1 after a rupture reduced water supply in the federal district (DF) by up to 40% in some areas.
The Cutzamala system, which includes of seven dams, requires significant repair work following 29 years of use. The new pipeline will allow repairs to be carried out without interruptions.
