BENEFITS OF HDPE CISTERNS: Durability and longevity. These tanks can last forever and can be easily repaired if they leak. Since it is high-density polyethylene, the plastic itself is very stable. Also, tanks can be installed using smaller equipment, so there is much more flexibility in location of installation.

DISADVANTAGES OF HDPE CISTERNS: Because the tanks themselves are relatively light-weight, precautions must be taken during installation to prevent damage to tanks and tank floating (i.e., tanks popping out of the ground). Tanks must be installed with a buffer backfill of a sand/gravel mixture, and, with the ribbed tanks, one quarter of the tank’s capacity must remain full of water at all times (this keeps the tank weighed down). We are proud to say that we have never had a HDPE cistern that we’ve installed float!
