Water catchment systems need an NSF-approved elastomeric roof coating if potable water is required. NSF-approved products provide assurance the water used in rainwater collection systems will be safe for clean water use.
NSF Protocol P151 and Standard 61 certification assures both public health officials and consumers that the system components are safe for use in rainwater collection systems and potable water applications respectively.
If potable water is needed, take care in selecting materials and elastomeric roof coatings which will come into contact with the water as it is collected, since some impurities can be picked up by the rainwater as it travels through the collection system.
