Mexican President Felipe Calderón was on hand to open the Acueducto II potable water pipeline in central Querétaro state, which required an investment of some 2.85bn pesos (US$237mn).
The new pipeline will provide an additional 47.3Mm3 of potable water for state capital Querétaro, national water authority Conagua reported on its website.
Construction included an 843,000m3 dam, two pumping stations and 123km of pipeline to channel water from springs in El Infiernillo to the system's potable water plant, which will treat 1,500l/s.
The project aimed to alleviate pressure on the Querétaro aquifer, where annual extraction currently reaches 110Mm3, while replenishment is only 70Mm3. The new system will allow the closure of 40 of the 83 wells tapping into the aquifer, which is expected to increase its replenishment by 7Mm3 annually.
The national government financed some 30% of the project's cost, with the reminder invested by concessionaire Controladora de Operaciones de Infraestructura, which includes ICA, Spain's FCC, as well as Aqualia, Gestión Integral del Agua and Servicios de Agua Trident.
