INSPECTION

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 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.

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.
