These tanks are lined to maintain water quality - quite small quantities of iron compounds can be tasted. The tanks must be easy to clean and disinfect and the steel protected from corrosion.

Whatever their size the coating systems applied to these tanks must meet strict criteria aimed at ensuring that the drinking water is both pure and taint-free. These coating systems are tested and approved by a number of recognised bodies.

PPG Marine Coatings has a range of specialised solvent free and solvent based coating systems specifically designed and approved for the safe storage of drinking water and for protecting the tanks from corrosion.
