Steel water storage silo / tank

Another usage of geosynthetics materials are in steel water reservoirs.

These are very practical and easy to use water storage systems.

They come with all the parts inside and you construct it on site.

Their heights are upto 4.64 meters and diameters vary from 1.85 to 30.95 meters.

Inside the steel construction there is a nonwoven geotextile liner to protect the waterproof tank liner. The tank liner can be made of PVC or other type of polymers depending on the usage.
