Poly tanks seem an attractive alternative to steel from the viewpoint of corrosion, base preparation and price. However:
- HDPE (High Density Polyethylene) is manufactured from petrochemicals. Difficult to dispose of in an environmentally/ecologically safe manner.
- Anecdotal evidence from our customers strongly suggests the smell and taste of plastic is evident in the water.
- Poor UV (Ultra Violet) resistance encourages algae growth and limits the capability of recycled plastic being used to make water tanks.
- Fire resistance is very poor.
- Steel offers good service life and is 100% recycleable.
