CITY OF FORT WORTH STORMWATER FACILITY
OPERATION, MAINTENANCE & INSPECTION PLAN
The only responsibility the City of Fort Worth has in the operation and
maintenance of this Facility is inspection.
General Maintenance Procedures
The structural and functional integrity of the Facility shall be maintained at all
times by removing and preventing drainage interference, obstructions, blockages,
or other adverse effects into, through, or out of the system.
The stormwater quality device shall be cleaned and cleared of all sediment shortly
after project completion. Generally, a sump-vacuum truck is the most convenient
method of removing the captured sediment and floatables from large underground
structures. Floatables and oil should be removed in a separate procedure prior to
the removal of accumulated sediment from the bottom of the underground storage
chambers. The structural and functional integrity of the Facility shall be
maintained at all times by following the manufacturer recommendations for
maintaining the system. Flushing of the system by hose or other method that may
move sediment to the downstream storm sewer system is unacceptable.
Periodic silt removal shall occur when standing water conditions occur or the
underground storage volume is reduced by more than 10%. This maintenance
should be performed as needed based on inspection but is recommended
annually. In addition, corrective measures are required any time a basin does not
drain completely within 72 hours of cessation of inflow.
Accumulated litter, sediment, and debris shall be removed every 6 months or as
necessary to maintain proper operation of the basin. Disposal shall be in
accordance with federal, state and local regulations. To prevent debris from
entering and clogging the downstream storm sewer system a wire mesh screen or
similar screening device shall be installed over the outlet until final acceptance.
PREVENTIVE MAINTENANCE/INSPECTION
• Visual inspections of all components will be conducted every 6 months.
• A log shall be kept of maintenance actions, and inspections. The log
should document the condition of the detention system's primary
components, silt, litter and debris removal dates. Document any
replacement or maintenance of structures.
• Written maintenance and repair records shall be maintained by the
party or parties signing the attached Agreement and shall be provided
to the City upon request
