It was considered dÃ©classÃ© to refer to one's own townhouses, estates or villas (or those of friends) as mansions and modern etiquette books still advise that the terms house, big house or great house be used instead.
Waste weir. A waste weir on a navigable canal is a slatted gate on each canal level or pound, to remove excess water and to drain the canal for repairs or for the winter shutdown.
End Connections. Openchannelflow Weir Boxes can be provided with a variety of end connections, including pipe stubs, flanges, and caulking collars to connect to piping. Pipes can enter / exit a Weir Box along the centerline, off-axis, or from the side. For applications where the pipes enter the Weir Box from the side or off-axis, additional baffling may be necessary. In addition to piped connection, Openchannelflow Weir Boxes can be configured so that flow freely spills into or out of the box as necessary. For applications where flow spills into the Weir Box, a splash guard may be necessary to minimize turbulence (or potentially foaming ) in the main weir pool.
