Outlet Barrels USDA NRCS Dewatering Pool Dewatering Pool Dewatering Pool FIGURE 7.5 Use of Baffles in Sediment Basins To avoid potential failure, outlet barrels should be installed early in the construction of the embankment rather than after the embankment is completed, and should drain to a stable receiving watercourse. Suitable outlet protection should be provided for all basin outfalls. Basins should not be constructed in locations where subsequent trenching for sewer lines and utilities will disturb the embankment. 363-2134-008 / March 31, 2012 / Page 202
Anti-seep Collar Wherever soils susceptible to piping are encountered, anti-seep collars or filter diaphragms should be installed with the outlet barrel. Figure 7.6 shows the critical dimensions for design of anti-seep collars. PA DEP EPA - 625/3-76-006 FIGURE 7.6 Anti-seep Collar Design 363-2134-008 / March 31, 2012 / Page 203
