Underground Water Storage

When it comes to rainwater harvesting and water storage, some homeowners (as well as facility managers) prefer to house tanks underground, as opposed to utilising vertical tanks above-ground. This may be due to aesthetics or, more likely, space constraints.

Underground plastic storage tanks can be used for the storage of rainwater as well as municipal water, grey water, conservancy water waste or any other liquid which may be stored underground legally.

Benefits & Advantages
  • Space – An underground tank will provide storage space, while being both out of the way and out of sight.
  • Longevity – Underground tanks are not exposed to the elements.
  • Safety –The underground tanks that we supply are equipped with child-safe manholes.
  • Containment – The tank is completely sealed and buried, so cannot be infested with any contaminants.
  • Size –Choose from a large variety of tank sizes.
  • Cost – A plastic underground tank costs less to install than brick-built tanks.
