PAVEMENT SURFACE HAS BEEN WETTED CONTINUOUSLY FOR AT LEAST 10 MINUTES. COMPLIANCE WITH THIS MINIMUM RATE SHALL BE CHECKED PRIOR TO
CONSTRUCTION APPROVAL OF THE PAVEMENT. COMPLIANCE MAY BE CHECKED USING A SIMPLE BUCKET TEST IN WHICH 5 GALLONS OF WATER IS POURED ONTO THE
PAVEMENT SURFACE ALL AT ONCE. IF ONLY A MINOR AMOUNT OF WATER PONDS OR RUNS OFF THE SURFACE, THEN THE PAVEMENT IS CONSIDERED TO MEET THE
MINIMUM RATE OF ABSORPTION. AT LEAST ONE TEST SHALL BE CONDUCTED PER 1,000 SQUARE FEET OF PERMEABLE PAVEMENT. IF THIS TEST IS NOT CONCLUSIVE,
THEN ANOTHER TEST PER ASTM C1701 .SHALL BE CONDUCTED. FOR LARGE AREAS (E.G., PARKING AREAS), TESTING OBSERVATION MAY BE. ACCOMPLISHED WHILE

NOTES:
1. THIS DETAIL IS A SCHEMATIC REPRESENTATION ONLY. ACTUAL CONFIGURATION WILL VARY DEPENDING ON SPECIFIC
SITE CONSTRAINTS AND APPLICABLE DESIGN CRITERIA.
2. GRAVITY DRAIN SHALL BE AT LEAST 8 INCH MINIMUM DIAMETER AND SHALL BE CONTROLLED BY A VALVE. USE OF A
SHEAR GATE IS ALLOWED ONLY AT THE INLET OF A PIPE LOCATED WITHIN AN APPROVED STRUCTURE.
3. ACCESS TO EACH COMPARTMENT IS REQUIRED, ON EACH END, AND EVERY 50 FEET MINIMUM.
4. VAULTS PROVIDING MANHOLE ACCESS AT 12 FOOT SPACING NEED NOT PROVIDE CORNER VENTILATION PIPES.
VENTILATION PIPES SHALL BE CAPPED OR OTHERWISE COVERED, BUT DESIGNED SO THAT MAINTENANCE PERSONNEL
CAN REMOVE FOR VENTILATION.
5. WHEN CONNECTING TO A NEW PIPE, USE A FLEXIBLE CONNECTOR (KOR-N-SEAL BOOT WITH CORRUGATED PIPE
ADAPTER OR APPROVED EQUAL). WHEN CONNECTING TO AN EXISTING PIPE, USE A FABRICATED SAND COLLAR OF THE
SAME MATERIAL AS THE CONNECTING PIPE.
