Sediment Row Inspection & Maintenance
12.1
Sediment Row Inspection
Inspecting and maintaining the HydroStor chamber system is critical to ensuring the stormwater
system will perform as designed. Buildup of debris in the chamber system may result in ineffective
operation or complete failure of the system. Inspection of chamber sediment row can be done
through the manhole or optional inspection ports on the chamber sediment row. All local and
OSHA rules must be followed for confined space entry.
Inspection ports offer the convenience of inspection from the ground surface without concern of
confined space entry. (Figure 18) Inspection ports allow for visual inspection with the use of a
flashlight or a long stick to measure the level of sediment.

12.2
Inspection Frequency
Initial inspection of the system is recommended soon after the site construction is completed.
Every effort should be made to keep sediment and debris out of the stormwater system during
construction; however, this is typically the time when excess amounts of sediment builds up. It is
recommended that the system be inspected and cleaned, if necessary, before passing the
responsibility over to the site owner.
Inspection frequency will vary based on the system design and requirements. A system inspection
schedule should be developed for each individual system, with the industry standard being a
minimum of twice per year. It is recommended that the inspections be tracked on an Inspection
and Maintenance log sheet.
