CITY OF FORT WORTH STORMWATER FACILITY
OPERATION AND MAINTENANCE 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.
Periodic silt removal shall occur when standing water conditions occur or the pond's
storage volume is reduced by more than 10%. Silt shall be removed and the pond/basin
returned to original lines and grades shown on the approved engineering plans. In
addition, corrective measures are required any time a basin does not drain completely
within 72 hours of cessation of inflow. NO STANDING WATER IS ALLOWED in
basins 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 basin. Disposal shall be in accordance with federal,
state and local regulations.
Detention facilities shall be mowed monthly between the months of April and October or
anytime vegetation exceeds 12 -inches in height.
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, mowing,
and silt, litter and debris removal dates. Document aeration of the basin bottoms
and replanting to prevent the sealing of the basin bottom.
• 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.

The Isolator® Row Plus
Introduction
An important component of any Stormwater Pollution Prevention Plan
is inspection and maintenance. The StormTech Isolator Row Plus is a
technique to inexpensively enhance Total Suspended Solids (TSS),
Total Phosphorus (TP), Total Petroluem Hydrocarbons (TPH) and
Total Nitrogen (TN) removal with easy access for inspection and
maintenance.
The Isolator Row Plus
The Isolator Row Plus is a row of StormTech chambers, either SC -160, SC -
310, DC -780, SC -800, MC -3500, MC -4500 or MC -7200 models, are lined with
filter fabric and connected to a closely located manhole for easy access.
The fabric lined chambers provide for sediment settling and filtration as
stormwater rises in the Isolator Row Plus and passes through the filter
fabric. The open bottom chambers allow stormwater to flow vertically
out of the chambers. Sediments are captured in the Isolator Row Plus
protecting the adjacent stone and chambers storage areas from sediment
accumulation.
ADS Isolator Row and Plus fabric are placed between the stone and the
Isolator Row Plus chambers. The woven geotextile provides a media for
stormwater filtration, a durable surface for maintenance, prevents scour
of the underlying stone and remains intact during high pressure jetting.
The Isolator Row Plus is designed to capture the "first flush" runoff and
offers the versatility to be sized on a volume basis or a flow -rate basis. An
upstream manhole provides access to the Isolator Row Plus and includes
a high/low concept such that stormwater flow rates or volumes that
exceed the capacity of the Isolator Row Plus bypass through a manifold to
the other chambers. This is achieved with an elevated bypass manifold or
a high -flow weir. This creates a differential between the Isolator Row Plus
row of chambers and the manifold to the rest of the system, thus allowing
for settlement time in the Isolator Row Plus. After Stormwater flows
through the Isolator Row Plus and into the rest of the chamber system
it is either exfiltrated into the soils below or passed at a controlled rate
through an outlet manifold and outlet control structure.
The Isolator Row Plus FlampTM is a flared end ramp apparatus attached to
the inlet pipe on the inside of the chamber end cap. The FLAMP provides
a smooth transition from pipe invert to fabric bottom. It is configured
to improve chamber function performance by enhancing outflow of
solid debris that would otherwise collect at the chamber's end, or more
difficult to remove and require confined space entry into the chamber
area. It also serves to improve the fluid and solid flow into the access pipe
during maintenance and cleaning and to guide cleaning and inspection
equipment back into the inlet pipe when complete.
The Isolator Row Plus may be part of a treatment train system. The
treatment train design and pretreatment device selection by the
design engineer is often driven by regulatory requirements. Whether
pretreatment is used or not, StormTech recommend using the Isolator
Row Plus to minimize maintenance requirements and maintenance costs.
Note: See the StormTech Design Manual for detailed information on designing
inlets for a StormTech system, including the Isolator Row Plus.
Looking down the Isolator Row
Plus from the manhole opening,
ADS Plus Fabric is shown between
the chamber and stone base.

Isolator Row Plus Inspection/Maintenance
Inspection
The frequency of inspection and maintenance varies
by location. A routine inspection schedule needs to
be established for each individual location based
upon site specific variables. The type of land use
(i.e. industrial, commercial, residential), anticipated
pollutant load, percent imperviousness, climate,
etc. all play a critical role in determining the actual
frequency of inspection and maintenance practices.
At a minimum, StormTech recommends annual
inspections. Initially, the Isolator Row Plus should
be inspected every 6 months for the first year of
operation. For subsequent years, the inspection
should be adjusted based upon previous observation
of sediment deposition.
The Isolator Row Plus incorporates a combination
of standard manhole(s) and strategically located
inspection ports (as needed). The inspection ports
allow for easy access to the system from the surface,
eliminating the need to perform a confined space
entry for inspection purposes.
If upon visual inspection it is found that sediment
has accumulated, a stadia rod should be inserted to
determine the depth of sediment. When the average
depth of sediment exceeds 3" (75 mm) throughout
the length of the Isolator Row Plus, clean -out should
be performed.
Maintenance
The Isolator Row Plus was designed to reduce the cost
of periodic maintenance. By "isolating" sediments
to just one row, costs are dramatically reduced
by eliminating the need to clean out each row of
the entire storage bed. If inspection indicates the
potential need for maintenance, access is provided

via a manhole(s) located on the end(s) of the row for
cleanout. If entry into the manhole is required, please
follow local and OSHA rules for a confined space
entry.
Maintenance is accomplished with the JetVac
process. The JetVac process utilizes a high pressure
water nozzle to propel itself down the Isolator Row
Plus while scouring and suspending sediments.
As the nozzle is retrieved, the captured pollutants
are flushed back into the manhole for vacuuming.
Most sewer and pipe maintenance companies have
vacuum/JetVac combination vehicles. Selection of an
appropriate JetVac nozzle will improve maintenance
efficiency. Fixed nozzles designed for culverts or large
diameter pipe cleaning are preferable. Rear facing
jets with an effective spread of at least 45" are best.
StormTech recommends a maximum nozzle pressure
of 2000 psi be utilized during cleaning. JetVac reels
can vary in length. For ease of maintenance, ADS
recommends Isolator Row Plus lengths up to 200'
(61 m). The JetVac process shall only be performed
on StormTech Isolator Row Plus that have ADS
Plus Fabric (as specified by StormTech) over their
angular base stone.
