Potable Water Liners
Potable water is water that must be safe for human consumption. Check local regulations for the liner materials approved for use in your area. Most areas require that liners for potable water are certified by the National Sanitation Foundation (NSF) to meet the NSF/ANSI 61 standard. NSF certified liners are inspected to insure that all ingredients including the polymer and additives such as UV stabilizers, heat stabilizers, antioxidants, etc. are safe for contact with drinking water. Common liner materials for potable water are NSF certified 36 and 45 mil Polypropylene.
