A method of coating potable water structures comprises applying a first resin to the interior surfaces of the structure and curing the resin to provide a primer layer; applying a second resin, containing a conductive filler, to the primer layer and curing the resin to provide a conductive layer; applying a first silica-reinforced resin to the conductive layer to provide an uncured basecoat precursor layer; applying a reinforcing fabric to the uncured basecoat precursor layer; applying a second silica-reinforced resin, which may be the same as or different from the first silica-reinforced resin, to the reinforcing fabric and curing the first and second silica-reinforced polymer resins to provide a basecoat layer; and applying a polymer suitable for contact with potable water to the basecoat layer and curing the polymer to provide a topcoat layer; wherein the method results in a coated surface that is suitable for contact with potable water and further wherein the coated surface is stable for a period of at least ten months after coating according to the method. A coated structure suitable for contact with potable water comprises a primer layer in contact with the interior surfaces of the structure; a conductive layer in contact with the primer layer; a silica-reinforced polymer resin basecoat layer in contact with the conductive layer, wherein the basecoat layer contains a reinforcing fabric; and a polymer topcoat layer in contact with the basecoat layer, wherein the polymer topcoat layer is suitable for contact with potable water.
