Pipe assembly for collecting surface water runoff and associated methods

摘要: The present invention includes a pipe assembly for collecting water runoff. plurality of elongated primary pipes disposed in adjacent contact along their lengths. Each pair define upper and lower voids between haunches imaginary planes tangential thereto. An secondary is each void its length with the two defining void. A material transversely encompasses pipes. may be used storage system methods installing such system. also method surface water. use flow path.
