Orifice Plates are generally used as part of an onsite detention system (OSD) to control and restrict the flow of water discharge to the council system.
All Mascot Engineering Orifice Plates come complete with holes in each corner for the restrictor to attach to the inside of the detention control pit (DCP). The orifice size is determined by the Hydraulic Engineer (private or council) and is based on the hard surface run off area of your site.
Stainless Steel Orifice Plates are available in SS304 and SS316 as required as well as a variety of thicknesses and sizes. Call 1300 885 295 to discuss your OSD requirements and see the below links for more information.
