INSPECTION & MAINTENANCE
STEP 1) INSPECT ISOLATOR ROW PLUS FOR SEDIMENT
A. INSPECTION PORTS (IF PRESENT)
A.1. REMOVE/OPEN LID ON NYLOPLAST INLINE DRAIN
A .2 . REMOVE AND CLEAN FLEXSTORM FILTER IF INSTALLED
A.3 . USING A FLASHLIGHT AND STADIA ROD , MEASURE DEPTH OF SEDIMENT AND RECORD ON MAINTENANCE LOG
A .4. LOWER A CAMERA INTO ISOLATOR ROW PLUS FOR VISUAL INSPECTION OF SEDIMENT LEVELS (OPTIONAL)
A.5 . IF SEDIMENT IS AT, OR ABOVE, 3' (80 mm) PROCEED TO STEP 2. IF NOT, PROCEED TO STEP 3 .
8 . ALL ISOLATOR PLUS ROWS
8 .1. REMOVE COVER FROM STRUCTURE AT UPSTREAM END OF ISOLATOR ROW PLUS
B.2 . USING A FLASHLIGITT, INSPECT DOINN TI-IE ISOLATOR ROW PLUS THROUGH CUTI.ET PIPE
I) MIRRORS ON POLES OR CAMERAS MAY BE USED TO AVOIDA CONFINED SPACE ENTRY
Ii ) FOLLOW OSHA REGULATIONS FOR CONFI NED SPACE ENTRY IF ENTERING MANHOLE
8 .3. IF SEDIMENT IS AT , OR ABOVE, 3" (80 mm) PROCEED TO STEP 2. IF NOT, PROCEED TO STEP 3.
STEP 2) CLEAN OUT ISOLATOR ROW PLUS USING THE J ETVAC PROCESS
A. A FIXED CULVERT CLEANING NOZZLE WITH REAR FACING SPREAD OF 45" {1.1 m)OR MORE IS PREFERRED
B. APPLY MULTIPLE PASSES OF JETVAC UNTIL BACKFLUSH WATER IS CLEAN
C. VACUUM STRUCTURE SUMP AS REQUIRED
STEP 3) REPLACE ALL COVERS, GRATES, FILTERS, ANO LIDS; RECORD OBSERVATIONS AND ACTIONS .
STEP 4) INSPECT AND CLEAN BASINS AND MANHOLES UPSTREAM OF THE STORMTECH SYSTEM .
NOTE S
1. INSPECT EVERY 6 MONTHS DURING THE FIRST YEAR OF OPERATION. ADJUST THE INSPECTION INTERVAL BASED ON PREVIOUS
OBSERVATIONS OF SEDIMENT ACCUMULATION AND HIGH WATER ELEVATIONS .
2. CONDUCT JETTING ANO VACTORING ANNUAL LY OR WHEN INSPECTION SHOWS THAT MAINTENANCE IS NECESSARY.
