Hydroelectric Reservoirs

Hydroelectricity involves the production of electrical power using the gravitational force of falling or flowing water and is currently the most widely used form of renewable energy in Guatemala and the rest of the world.  As a result, hydroelectric installations are on the rise in Guatemala and Central America. To contain water, hydroelectric plants require very large reservoirs. Geomembranes provide an impermeable barrier for water retention superior to concrete or asphaltic lining in both cost and lower permeability. The geomembranes OMALI offers, have great engineering properties from their high elasticity, waterproofing and overall excellent mechanical resistance under tensile, tear and puncture modes, making them especially reliable in seismic zones. OMALI’s geomembranes have been used in the most important hydroelectric projects in Guatemala, including Xacbal, Palo Viejo, Renace I, La Perla and other.

Here are several factors to consider when deciding which type of geomembrane to use in a Hydroelectric Dam or Reservoir application:

  • Stress crack resistance
  • Temperature range
  • U.V exposure
  • Tensile and elongation properties
  • Duration of the project
  • Hydrostatic pressure
  • Interface friction (slope angles)
