When the proprietors of lumber yards, garages, shops, halls, stores, hotels or public buildings, regular customers of the water works, wish to lay larger pipes with hydrants and hose couplings, to be used only in case of fires, they will be permitted to connect with the street main at their own expense, upon granting of permit by the Superintendent, and will be allowed to use the water for fire purposes only, free of charge. All water lines laid for private free fire protection must be plastic not less than 150-pound class and must be four inches inside diameter or larger.
(Prior Code, § 13-1-19)
