Abstract: A non-clogging facility (10) collects debris and sediment carried by water flowing in an open channel (DC) upstream of an inlet (I) to a conduit. A first section (12) provides a transition from the open channel into a second section (13) which allows for collection of large debris and readily settleable sediment. A barrier (16) comprises a base (18) extending from a sidewall (W1) on one side of the channel, substantially across the width of the channel, toward the opposite sidewall (W2). An opening (20) is provided between the end of this barrier and the opposite sidewall. Water flowing at a low rate is diverted through the opening into a bypass channel (22) to flow to the inlet through a third section (14). At higher flow rates, water flows over the barrier and through a screen formed by a series of spaced posts (26) extending the length of the barrier. Sediment settles to a floor (F) of the channel upstream of the barrier and is blocked by the barrier from moving further downstream.

Abstract: A clip-type support for use in installing trench drain systems. The clip device has two clip structures spaced from each other along a central web to engage, clamp and support two inter-engaging end portions of adjacent drain channel sections. A middle portion of the clip device separating the two clip structures has two deformable tabs, each located on opposite sides of the web.
