INSPECTION

GENERAL STATEMENT

Regular inspections are recommended to ensure that the system is functioning as designed. Inspections
should be a part of the standard operating procedure. The required frequency of cleanout depends on site use
and other site-specific characteristics and should therefore be determined by inspecting the unit after
installation. During the first year of operation, the unit should be inspected at least every six months to
determine the rate of sediment and floatable material accumulation. More frequent inspections are
recommended at sites that would generate heavy solids loads, like parking lots with winter sanding or
unpaved maintenance lots. In cases where inspection is performed on an annual basis, the inspection should
be conducted before the stormwater season begins to ensure that the system is functioning properly for the
upcoming storm season.

INSPECTION PROCESS

Inspection should be performed when water conditions are static to avoid interruption during the
maintenance duration. Refer to your local and national regulations for any additional inspection requirements
and schedules not contained herein. Brief steps of the inspection process are summarized below.
 Perform visual inspection at all manhole locations.
 Visually check for debris accumulation on the StormTEE
 Utilize a sediment pole to measure and document the amount of sediment accumulation in both
chambers. Refer to "How to Check the Sediment Depth" section for additional details.
 Inspect the inlet and outlet pipe opening to ensure that the silt level or any foreign objects are not
blocking the pipes.
It is recommended to visually inspect all pipes and connection for any possible leaks and findings will
need to be reported to the contractor.

HOW TO CHECK THE SEDIMENT DEPTH

To determine the amount of sediment in the treatment chamber, which contains the BioSTORM
 Open the access ports or cover(s) of the treatment zone
 Insert a sediment pole to the top of the sediment layer and record the depth.
 Insert the pole to the bottom of the system and record the depth.
 The difference in the two measurements corresponds to the amount of sediment in the treatment
chamber.
 NJDEP requires sediment removal on or before it reaches the maximum allowable depth per model size
(50% of the MTD's maximum storage depth). Consult your local distributor or the factory for guidance.
We recommend that you pump both chambers even if only one chamber requires pumping. Pump the
settling chamber first, which contains the STORMTEE® and then the treatment chamber, which
contains the interceptor
®
and the interceptor.
