PLACE TEMPORARY SEDIMENT CONTROLS BELOW THE BASIN AS NEEDED.
2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS,
WOOD VEGETATION, ORGANIC MATTER AND OTHER OBJECTIONABLE MATERIAL
PLACE THE FILL IN LIFTS NOT TO EXCEED 9 INCHES AND MACHINE COMPACT IT.
OVER FILL THE EMBANKMENT 6 INCHES TO ALLOW FOR SETTLEMENT.
3. SHAPE THE BASIN TO THE SPECIFIED DIMENSIONS. PREVENT THE SKIMMING
DEVICE FROM SETTLING INTO THE MUD BY EXCAVATING A SHALLOW PIT UNDER
THE SKIMMER OR PROVIDING A LOW SUPPORT UNDER THE SKIMMER OF STONE
OR TIMBER.
4. PLACE THE BARREL ON A FIRM, SMOOTH FOUNDATION OF IMPERVIOUS SOIL.
PLACE THE FILL MATERIAL AROUND THE PIPE SPILLWAY IN 4 INCH LAYERS AND
COMPACT IT UNDER AND AROUND THE PIPE TO AT LEAST THE SAME DENSITY AS
THE ADJACENT EMBANKMENT. PLACE A MINIMUM OF 2 FEET OF COMPACTED
BACKFILL OVER THE PIPE SPILLWAY BEFORE CROSSING IT WITH CONSTRUCTION
EQUIPMENT.

6. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE
FLEXIBLE JOINT AT THE INLET OF THE BARREL PIPE. ATTACHED THE FLEXIBLE
JOINT TO THE BARREL PIPE AND POSITION THE SKIMMER OVER THE EXCAVATED
PIT. ATTACH A ROPE TO THE SKIMMER AND ANCHOR IT TO THE SIDE OF THE
BASIN.
7. INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST EXTEND
POSSIBLE. THE SPILLWAY SHOULD BE LINED WITH LAMINATED PLASTIC OR
IMPERMEABLE GEOTEXTILE FABRIC. THE FABRIC MUST BE WIDE AND LONG
ENOUGH TO COVER THE BOTTOM AND SIDES AND EXTEND ONTO THE TOP OF
THE DAM FOR ANCHORING IN A TRENCH. THE EDGES MAY BE SECURED WITH 8
INCH STAPLES. THE FABRIC MUST BE LONG ENOUGH TO EXTEND DOWN THE
SLOPE AND EXIT ONTO STABLE GROUND. THE WIDTH OF THE FABRIC MUST BE
ONE PIECE. IF MULTIPLE SECTIONS AREA REQUIRED, THE UPPER SECTION
SHOULD OVERLAP THE LOWER SECTION SO THAT WATER CANNOT FLOW UNDER
THE FABRIC.
8. DISCHARGE WATER INTO THE BASIN TO PREVENT EROSION. USE TEMPORARY
SLOPE DRAINS OR DIVERSIONS WITH OUTLET PROTECTION TO DIVERT SEDIMENT
LADEN WATER TO THE UPPER END OF THE POOL AREA TO IMPROVE BASIN TRAP
EFFICIENCY.
9. CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS MINIMIZED.
DIVERT SURFACE WATER AWAY FROM BARE AREAS. COMPLETE THE
EMBANKMENT BEFORE THE AREA IS CLEARED.
10. INSTALL POROUS BAFFLES AS SPECIFIED.
