Background

In April 2023, the CC Hydro GCCB* was used to remediate an evaporation pond in Qatar. The client required the permanent evaporation ponds to capture both rain and contaminated water, mitigating any potential contamination of the ground and flooding around sensitive structures.

Solution

The evaporation pond was designed to capture rain-water during a 1/100 year storm event and was lined with a waterproofing membrane. Overtime, damage to the membrane led to water seepages causing contamination of the surrounding area. To resolve this issue, the client planned to remediate their evaporation pond to improve its containment function.

A number of solutions were proposed to remediate the evaporation pond, including the relining of the pond with another waterproof liner. However, potential damage from hoses and other hardware posed a risk to seepage issues returning so was dismissed. CCHT2^™ was chosen to line the pond due to the materials chemical resistance to hydrocarbons, puncture and having a low permeability.

Design & Installation

Prior to installation exsiting liner was removed
Sand was laid and compacted to create a uniform surface
CCHT2^™ Bulk Rolls specified
Vertical and longitudinal layup
Thermally welded overlaps
CCHT2^™ hydrated at night due to high temperatures

Conclusion

The project was completed in 53 days, with 9,600m² of CCHT2^™ installed by 15 technichians and an additonal 10 labourers working 10 hour days. The client was pleased with the project, with the CCHT2^™ meeting their expectations and have looked to use the material for further projects within their facility.
