Dams and power plants

The Multipurpose Rio Verde Project

The multipurpose Rio Verde project took place in the Rio Verde district, in the Esmeraldas province, in northern Ecuador. It covered the pre-feasibility, feasibility and final design phases.

The aim of this project was: to supply drinking water to the main urban centres of the district, to provide water to irrigate 7,300 hectares of land and to control and minimise the effect of floods in Chumundé, Rioverde, Montalvo and Lagarto.

In order to achieve these goals, the following structures were designed:

  • The Chumundé Dam: Type: homogeneous. Height: 33.7 metres. Control volume: 29.63 Hm
  • The Meribe Dam: Type: embankment (overflow) Height: 13 metres. Control volume: 6.47 Hm 3.
  • Catchments: each one has a diversion dam (3 m in height), a channel (25 m in length), a storage reservoir (average volume 75,000 m³ and a surface area of 25,000 m²) and a pumping station (flow rate of up to 1.08 m³/s, manometric pump head of 72.5 metres and a power of 1023 kW). Six catchments were installed in the Rioverde River basin.
  • Electrical substations: due to the increase in the power demand by the pumping system, it was necessary to expand the only station in the area to 3 MVA and build a new one with a power capacity of 5 MVA. 
  • Riverbank protection: the full length of the defences (rock-fill) and river channelling for protection against floods was 6,100 meters.
