CMP DETENTION SYSTEM INSPECTION AND
MAINTENANCE
UNDERGROUND STORMWATER DETENTION AND INFILTRATION SYSTEMS MUST
BE INSPECTED AND MAINTAINED AT REGULAR INTERVALS FOR PURPOSES OF
PERFORMANCE AND LONGEVITY.
INSPECTION
INSPECTION IS THE KEY TO EFFECTIVE MAINTENANCE OF CMP DETENTION
SYSTEMS AND IS EASILY PERFORMED. CONTECH RECOMMENDS ONGOING,
ANNUAL INSPECTIONS, SITES WITH HIGH TRASH LOAD OR SMALL OUTLET
CONTROL ORIFICES MAY NEED MORE FREQUENT INSPECTIONS THE RATE AT
WHICH THE SYSTEM COLLECTS POLLUTANTS WILL DEPEND MORE ON SITE
SPECIFIC ACTIVITIES RATHER THAN THE SIZE OR CONFIGURATION OF THE
SYSTEM
INSPECTIONS SHOULD BE PERFORMED MORE OFTEN IN EQUIPMENT
WASHDOWN AREAS, IN CLIMATES WHERE SANDING AND/OR SALTING
OPERATIONS TAKE PLACE, AND IN OTHER VARIOUS INSTANCES IN WHICH ONE
WOULD EXPECT HIGHER ACCUMULATIONS OF SEDIMENT OR ABRASIVE/
CORROSIVE CONDITIONS. A RECORD OF EACH INSPECTION IS TO BE
MAINTAINED FOR THE LIFE OF THE SYSTEM
MAINTENANCE
CMP DETENTION SYSTEMS SHOULD BE CLEANED WHEN AN INSPECTION
REVEALS ACCUMULATED SEDIMENT OR TRASH IS CLOGGING THE DISCHARGE
ORIFICE.
ACCUMULATED SEDIMENT AND TRASH CAN TYPICALLY BE EVACUATED
CONSTRUCTION LOADING THROUGH THE MANHOLE OVER THE OUTLET ORIFICE IF MAINTENANCE IS NOT
TYPICALLY, THE MINIMUM COVER SPECIFIED FOR A PROJECT ASSUMES H-20 PER FORMED AS RECOMMENDED, SEDIMENT AND TRASH MAY ACCUMULATEIN
LIVE LOAD BECAUSE CONSTRUCTION LOADS OFTEN EXCEED DESIGN LIVE FRONT OF THE OUTLET OR IFICE. MANHOLE COVERS SHOULD BE SECURELY
LOADS, INCREASED TEMPORARY MINIMUM COVER REQUIREMENTS ARE SEATED FOLLOWING CLEANING ACTIVITIES. CONTECHSUGGESTSTHATALL
AT
NECESSARY. SINCE CONSTRUCTION EQUIPMENT VARIES FROMJOBTOJOB, SYSTEMS THE
WITH AN LET ORIFICE.
SHOULD ON
IT B NE ESSATEDO
IT IS BEST TO ADDRESS EQUIPMENT SPECIFIC MINIMUM COVER GET OR NEAR THE INLET SYSTEM THEOUTLR ORIFICE. MAINTENANCE
ACTIVITIES,
NECESSARY TO
REQUIREMENTS WITH YOUR LOCAL CONTECH SALES ENGINEER DURING APPROPRIATE
THE PRECAEMONSR TO GORMMAINTEFIND ACTIVITIES,ALL
APPROPRIATE PRECAUTIONS REGARDING CONFINED SPACE ENTRY AND
YOUR PRE -CONSTRUCTION MEETING. OSHA REGULATIONS SHOULD BE FOLLOWED.
ADDITIONAL CONSIDERATIONS
BECAUSE MOST SYSTEMS ARE CONSTRUCTED SELOW-GRADE, RAINFALL
CAN RAPIDLY FILL THE EXCAVATION; POTENTIALLY CAUSING FLOATATION
AND MOVEMENT OF THE PREVIOUSLY PLACED PIPES. TO HELP MITIGATE
POTENTIAL PROBLEMS, IT IS BEST TO START THE INSTALLATION AT THE
DOWNSTREAM END WITH THE OUTLET ALREADY CONSTRUCTED TO ALLOW
A ROUTE FOR THE WATER TO ESCAPE. TEMPORARY DIVERSION MEASURES
MAY BE REQUIRED FOR HIGH FLOWS DUE TO THE RESTRICTED NATURE OF
THE OUTLET PIPE.

B�xsxsD rsv�xBcnoxwcsysrex �� omu:r coxTaa
ANNUAL INSPECTIONS ARE BEST PRACTICE FOR ALL UNDERGROUND
SYSTEMS. DURING THIS INSPECTION, IF EVIDENCE OF SALTING/DE-ICING
AGENTS IS OBSERVED WITHIN THE SYSTEM, IT IS BEST PRACTICE FOR THE
SYSTEM TO BE RINSED, INCLUDING ABOVE THE SPRING LINE SOON AFTER THE
SPRING THAW AS PART OF THE MAINTENANCE PROGRAM FOR THE SYSTEM.
MAINTAINING AN UNDERGROUND DETENTION OR INFILTRATION SYSTEM IS
EASIEST WHEN THERE IS NO FLOW ENTERING THE SYSTEM. FOR THIS
REASON, IT IS A GOOD IDEA TO SCHEDULE THE CLEANOUT DURING DRY
WEATHER.
THE FOREGOING INSPECTION AND MAINTENANCE EFFORTS HELP ENSURE
UNDERGROUND PIPE SYSTEMS USED FOR STORMWATER STORAGE CONTINUE
TO FUNCTION AS INTENDED BY IDENTIFYING RECOMMENDED REGULAR
INSPECTION AND MAINTENANCE PRACTICES. INSPECTION AND MAINTENANCE
RELATED TO THE STRUCTURAL INTEGRITY OF THE PIPE OR THE SOUNDNESS
OF PIPE JOINT CONNECTIONS IS BEYOND THE SCOPE OF THIS GUIDE.

CITY OF FORT WORTH STORMWATER FACILITY OPERATION AND
MAINTENANCE PLAN FOR UNDERGROUND FACILITIES
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.
Periodic silt removal shall occur when standing water conditions occur or the facilities
storage volume is reduced by more than 10%. Silt shall be removed and the facility returned
to original working condition of the lines and grades shown on the approved engineering
plans. In addition, corrective measures are required any time a facility does not drain
completely within 72 hours of cessation of inflow. NO STANDING WATER IS
ALLOWED in the underground facility designed for dry detention purposes.
Accumulated litter, sediment, and debris shall be removed every 6 months or as necessary
to maintain proper operation of the facility. 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.
4. 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.
• 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.
