Friday, November 4, 2011

Planned irrigation modernization works in Mexico's Cuatrociénegas valley in Coahuila state will require a 600mn-peso (US$44.5mn) investment, according to a study undertaken on behalf of national water authority Conagua.

The most urgent works include enclosing irrigation canals with tubing to reduce leaks. Other modernization works will bring the total estimated investment to 1.97bn pesos, the water authority said in a release.

Conagua has spent 111mn pesos on water protection projects in the area since 2009 and expects to complete 21.8km of tubing along the La Becerra canal by the end of November.

The new tubing is expected to save 6Mm3/y of water, the release said.

The works are part of a wider irrigation program in the Cuatrociénegas valley and include construction of additional wells and channels as well as feasibility studies on the construction of artificial canal intersections.

The study commissioned by Conagua identified the type of water infrastructure projects required to ensure sustainable water use in the region.
