WATER SUPPLY PRESERVATION 

 

Introduction to the Problem 

Water Containment Systems

   

The containment and protection of important 

water supplies is a challenge to public works 

agencies as well as to industry.  Effective lining 

of potable water reservoirs can conserve 

millions of gallons of water by preventing 

seepage losses.  Additionally, covers can 

prevent contamination, control evaporation and 

prevent chlorine loss.  Similar containment and 

protection is needed in waste water treatment 

facilities, though the purpose is to prevent 

leakage of untreated liquids and to collect 

biodegradation gases such as methane.  

 

Water Conveyance Systems

   

The prevention of seepage from lined and 

relined canals is critical in arid regions. 

 

Similarly, storm water retention and detention 

facilities are lined with a geomembrane or GCL 

to prevent excess wetness or instability of 

surrounding property resulting from seepage of  

contained runoff.
