The project team for the Canal do S

The project team for the Canal do Sertão scheduled construction in three stages, beginning in 2010. The objective was to capture 26 m3/s of water from the São Francisco River to supply the rivers and reservoirs for the 390 cities of the Sertão Nordestino. Several construction companies, design teams and applicators were involved in the different stages to construct an ambitious 1,000 km water channel. This consisted primarily of trapezoidal concrete sections that utilized a HDPE membrane under the concrete elements as the sole waterproofing system. Additionally, 20 km of elevated aqueducts, pump stations, flood gates and small hydroelectric plants were to be built where no waterproofing system had been specified at the design stage.
