ABSTRACT OF THE INVENTION A below ground drain and conduit member to receive surface water which also functions as an expansion and contraction joint is provided. The member comprises a hollow longitudinal member having an integrally joined upper polygonal portion (14) of a relatively narrower transverse dimension and a cylindrical lower portion (12) which may be anchored to the subsoil or a substrate and accommodates within said lower portion a cylindrical pipe to carry away accumulated water. The structural components are particularly adapted to be soldered or welded to form a water tight drainage system. The drain of the invention is adapted to be aligned and secured by attaching clips (80) which may be secured, such as by stakes driven into the subsoil, to prevent dislocation as concrete is poured around the drain. Water to be drained enters openings (23) in the top side, i.e. the horizontal face (22) of the upper portion (14) and is carried away in the cylindrical lower portion (12) which is in open communication with the upper portion. A channel, or indentation (24) in the outer surface of the drain enhances the attachment, i.e. bonding of the drain in the surround- ing concrete. Extensions (32) contiguous to the bottom of the drain, which mate with attachable securing clips (80) afford means to align and hold the drain during installation.
