*Where proposed Adapted from Westmoreland Conservation District STANDARD CONSTRUCTION DETAIL # 7-17 Concrete Cradle for Basin or Trap Outlet Barrel CROSS-SECTION AT OUTLET BARREL Note: A concrete cradle may be used in conjunction with anti-seep collars and/or filter diaphragm. Anti-seep collar number, size and spacing shall be as shown elsewhere in plan. Filter diaphragm location (LFD) shall be as shown in Figure 7.8. 363-2134-008 / March 31, 2012 / Page 210
Sediment Storage Zone Dewatering Prior to backfilling a sediment basin or converting it to a permanent stormwater facility, the sediment storage zone should be dewatered. This can be done by use of a dewatering facility such as the one shown in Standard Construction Detail #7-18, by pumping through a pumped water filter bag shown in Standard Construction Detail # 3-16, or by pumping to a nearby basin or trap as discussed in Dewatering Work Areas. PA DEP STANDARD CONSTRUCTION DETAIL # 7-18 Sediment Basin or Sediment Trap Sediment Storage Dewatering Facility Dewatering facility shall be installed immediately upon completion of basin/trap. Prior to initiating operation of dewatering facility, all accumulated sediment shall be cleaned from the inside of the barrel. Dewatering facility shall be continuously monitored during operation. If for any reason the dewatering facility ceases to function properly, it shall be immediately shut down and not restarted until the problem has been corrected. Provide construction details for each proposed sediment basin on the E&S plans. The plan view should indicate the principal and emergency spillway locations, the inlets from all pipes and interceptor channels, and any proposed outlet protection. Also provide a construction detail of the principal and emergency spillways showing all critical dimensions and elevations. A summary table showing all critical dimensions and elevation for each basin is recommended for sites having more than one basin. 363-2134-008 / March 31, 2012 / Page 211
