Mexico's Sonora state water authority CEA plans to tender construction of the second stretch of the Independencia potable water pipeline by end-April, CEA's director of water infrastructure, Antonio Cruz, told BNamericas.
The executive project for the 45km pipeline, which will complete the 180km pipeline from El Novillo reservoir to state capital Hermosillo, is currently being finalized, Cruz said. The pipeline will transfer 2.4m3/s of water to two potable water plants to be built near Hermosillo.
Construction of the potable water plants is also scheduled to be tendered. However, the awardee of the pipeline project may see its contract extended to include the plants so as to save time, according to Cruz.
With a total cost of 3.6bn pesos (US$301mn), the pipeline initiative aims to improve access to potable water in the capital, which is seeing its growth limited by lack of available water supply.
"It's not just growth, but the normal supply that a city should have is not being covered. We're talking about a situation in Hermosillo where we have potable water for eight hours in one area, another eight hours in another and finally we are distributing the amount of potable water we have in a 24-hour period in different sectors of the city," Cruz added.
Consortium Exploraciones Mineras del Desierto, comprised of 16 local firms, kicked off construction on the first 135km stretch of the pipeline on February 28. Both stretches are scheduled to be completed by June 2012.
The Independencia pipeline is part of Sonora's 11bn-peso Sonora SI integrated water plan, which was officially launched in April last year. The program also involves building six new dams and reservoirs, as well as new potable water plants.
