The calibre of a fibreglass tank is dependent upon its manufacturer, so be certain that you look at the quality thoroughly prior to picking this substance.
Steel Water Tanks

Lime, which can be found in concrete, may also flow into the water. They are usually installed underground for industrial purposes but may be utilized for residential use too.
Polyethylene Water Tanks
As this is exactly what National Poly Industries market we clearly have a ton more to say but will nonetheless attempt to stay impartial.
Primarily, some Principal advantages include:
Unlike metal tanks, poly rainwater tanks also indicate that you don’t have any requirement of poly liners found in tanks–because poly tanks are completely manufactured from food-grade polyethylene.
