Geosynthetics in Water Storage Lining

With global warming and changes to the climate, water is becoming an even more precious resource. The demand is increasing on water sources for irrigation of agriculture, sports fields, mining processes and for potable purposes.

Some of these water sources are considered wastewater or contaminated water so they must all be lined to limit the impact to the environment. The consequences to the environment commonly results from leaking dams which often leads to embankment instability (soil saturation) and potential catastrophic slopes failures and/or to ground water contamination.

Geofabrics' primary lining systems include Elcoseal Geosynthetic Clay Liner (GCL), Atarfil High Density Polyethylene (HDPE) and Teranap Bituminous Geomembrane (BGM). These liners when combined with drainage geocomposites (Flownet or Trinet), protective cushion geotextiles (Bidim) or electrical leak locating geotextiles (Bidim C), can vastly increase the longevity of the system depending on the surrounding environment and the exposure risk. Depending on the UV exposure, thermal impacts, surrounding chemistry and the consequence of failure, the appropriate lining system can be selected and ensure the water storage asset can last for the desired lifetime.
