The project, developed on a 24 000 ha area and divided into eleven blocks, integrates:

  • Pedrogão Pumping Station (H=78 m; Q=12,55 m³/s) and elevation pipeline (1800 m, DN 2500);
  • Pedrogão reservoir with 145 dam³ capacity;
  • Main pipeline gravitational system (28 km), included a Channel stretch with 1,75 km length and pipelines with variable diameters (DN400 to DN2500) and Qmax = 11,45 m³/s;
  • São Pedro Dam, V=10 hm³ and H=24 m;
  • Selmes-EE2 Pumping Station with two energy levels (EE2.1 -H=70 m, Q=0,55 m³/s; EE2.2 – H=90 m, Q=1,36 m³/s);
  • Selmes reservoir with 25 dam³ capacity;
  • Pedrógão 3 Pumping Station (H=80,9 m; Q= 12,50 m³/s);
  • Pedrógão 1 Pumping Station (H=116,5 m; Q= 0,11 m³/s);
  • Secondary Irrigation network: Pedrogão 1 (612 ha), Pedrógão 3 (1439 ha) and Selmes 2+Selmes 5 (1438 ha);
  • 6,4 km of secondary drainage network;
