Brian Fraser, Vice President Geosynthetics USA, was chosen to present his paper at this years Geosynthetics Conference 2019 in Houston, Texas. Brian presented his paper that outlines the long term performance and the history of CSPE in potable water storage applications.

Chlorosulfonated polyethylene (CSPE) is a synthetic rubber material noted for its outstanding resistance to chemicals, temperature extremes, and ultraviolet light.  CSPE as a geomembrane was first developed over 40 years ago in the United States as a pond liner material and a roofing membrane.  It has also been used extensively in various regions of the world as a geosynthetic floating cover material for municipal potable water storage and industrial process water containment applications.  CSPE floating covers are designed and used to eliminate evaporation and to prevent contamination and debris from entering the stored water source.

This paper highlights the long history of CSPE floating covers in potable water storage and the materials outstanding UV performance and chemical resistance to chlorine and other chemicals disinfectants used in water treatment.  The paper further profiles three larger floating cover projects located in hot, dry regions for potable water containment where the covers were used in exposed applications for an average of 30 years.  Two of these floating cover projects are in California and the third in the State of South Australia.  In potable water applications, disinfectants including chlorines and chloramines are commonly used for water treatment. These disinfectants can often act as accelerators in the breakdown of the certain geomembrane anti-oxidant packages resulting in premature material aging and failure.  With CSPE, the material goes through a unique polymer cross linking process where several of the product’s mechanical and endurance properties improve as the material ages.

With over forty years of documented applications, CSPE has proven to be one of the best performing materials for floating covers and geomembranes in long term potable water storage applications.
