Water Quality BMPs
Water Quality Best Management Practices (BMPs) are vegetative, structural, and other measures that
reduce or eliminate pollutants that might otherwise be carried by surface runoff. Potential pollutant
sources include litter form patrons and automobile fluids on the pavement including heavy metals, oil,
grease, and alcohols. The stormwater for the site drains via shallow and concentrated flow to a
proposed storm network and through structural water quality units prior to outletting into a wet
detention pond. Wet detention ponds are designed with outlet control structures that slow the release
of the stormwater. This allows pollutants and sediment to settle out prior to stormwater leaving the
detention area.
BMPs for Courtyards of Carmel Section 1 will include:
2 Water Quality Structures (#546A and #551A)
Wet Detention Ponds #1 and #2
See Attachment A for a BMP Location Map for this project.

Contact: Mark Gradison
Address: 6330 East 75th Street, Suite 156, Indianapolis, IN 46250
Business Phone Number: 317-594-7575
Party Responsible
The BMP owner agrees to pay all the fees required by the City of Carmel, including annual inspection
fees, and/or any additional fees required. Routine inspections are the responsibility of the BMP owner.
Maintenance is also the responsibility of the owner. The City of Carmel must be notified of any changes
in BMP ownership, major repairs, or BMP failures in writing within 30 days. The letter should be
addressed to:
Storm Water Program
Carmel Engineering Dept.
One Civic Square
Carmel, IN 46032
In the event that the City of Carmel finds a BMP in need of maintenance or repair, the City of Carmel will
notify the BMP owner of the necessary maintenance or repairs and give the BMP Owner a timeframe for
completing the maintenance or repairs. If the maintenance or repairs are not completed within the
designated timeframe, the City shall perform the repairs or maintenance and bill the BMP Owner the
actual cost of the work.
Submittal of annual inspection reports to the City of Carmel Engineering are due one year after
construction is completed, with subsequent reports due each year within the same month of the initial
report, any deficiencies found during the inspections should be addressed, and the BMP owner faces
enforcement action from the City if the inspection report is not received within the month it is due, if
there are deficiencies which were not included in the report, or if any deficiencies included in the report
are not addressed in a timely manner.
Material Handling
Disposal of waste from maintenance of drainage facilities shall be conducted in accordance with federal,
state, and local regulations. Removed sediment must be handled and disposed of in the garbage as solid
waste. Water should be disposed of in a sanitary sewer after oils are removed using oil absorbent
materials or other mechanical means. Used oil absorbents should be recycled or disposed according to
the manufacturer's instructions.
Safety
Work inside underground structures requires special OSHA -required confined space equipment and
procedures. The most practical option to perform maintenance or repairs is to contract with a sewer -
cleaning contractor
Storm Structure Maintenance and Inspection
Storm structures on site are identified within the construction plans set. Storm structures are set at
storm sewer pipe connections. Unless you have OSHA approved training and equipment, never enter a
manhole. Inspection and maintenance of all storm structures is required per the table below.
Storm Structure Maintenance and Inspection
Inspection
All inlet castings should be inspected every 6 months and after
each major rainfall event. More frequent inspections should be
performed in areas where there is higher potential for trash or
litter and during the fall when leaves are present on the ground.
Check the frame and lid for cracks and wear, such as rocking lids
or lids moved by traffic.
Storm structures and the surrounding areas should be inspected
annually for pollutants such as leaks from dumpsters, minor
spills, and oil dumping. Take action to have the pollutant source
removed.
Cleaning
Clean structures when there is a blockage of a water flow path
or when sediment depth reaches 10% of the pipe diameter.
Cleaning should be performed in a way that ensures removed
sediment and water is not discharged back into the storm sewer.
Materials Handling
Disposal of waste from maintenance of drainage facilities shall
be conducted in accordance with federal, state, and local
regulations. Removed sediment must be disposed in the garbage
as solid waste. Water should be disposed of in a sanitary sewer
after oils are removed using oil absorbent materials or other
mechanical means. Used oil absorbents should be recycled or
disposed according to the manufacturer's instructions.
Repairs
Repair all security and access features so they are fully
functional. This includes locking lids, covers, and ladder rungs.
Replace broken parts or lids that rock or are moved by traffic.
Storm Sewer Maintenance and Inspection
Storm sewer pipes convey stormwater. Pipes are built from many materials and are sometimes
perforated to allow stormwater to infiltrate into the ground. Storm pipes are cleaned to remove
sediment or blockages when problems are identified. Storm pipes must be clear of obstructions and
breaks to prevent localized flooding. Storm sewer maintenance and inspection required per the table
below.
Storm Sewer Maintenance and Inspection
Inspection
Pipes are difficult to inspect requiring special equipment and
training. Usually, if a problem occurs the owner needs to call a
sewer or plumbing contractor to inspect, repair or clean
pipelines.
Cleaning
Clean pipes when sediment depth is greater than 10% of the
pipe diameter. When cleaning a pipe, minimize sediment and
debris discharges from pipes to the storm sewer. Install
downstream debris traps (where applicable) before cleaning and
then remove material. Generally, use mechanical methods to
remove root obstructions from inside storm sewer pipes. Do not
put root -dissolving chemicals in storm sewer pipes. If there is a
problem, remove the vegetation over the line.
Materials Handling
Sediment and debris from pipes should be disposed in the
garbage as solid waste. Pick out any rocks first.
Repairs
Repair or replace pipes when a dent or break closes more than
20 percent of the pipe diameter. Repair or replace pipes
damaged by deterioration.
Turf Vegetative Coverage
All non -paved areas that are not landscaped shall be vegetated to prevent erosion and sediment buildup
in storm sewer facilities onsite or downstream of the project site. Seed shall be reapplied as required to
establish healthy, dense coverage.
Detention Maintenance and Inspection
Inspection of the proposed wet ponds is important for overall operation efficiency of the stormwater
management system, stormwater quality, as well as identifying potential problems.
The wet detention system should be inspected and maintained as follows:
1. Wet detention slopes and embankments: Inspect for erosion along pond surfaces at least
twice a year. Inspect for embankment damage annually. Dry detention slopes and
embankments shall be mowed as necessary and shall be clear of plants in excess of 5 inches
in height.
2. Wet detention bottom: Inspect wet detention basin for sediment accumulation and dead or
damaged ground cover annually. Remove sediments when storage volume is reduced by
25%. Sediments and waste shall be disposed of in accordance with the City of Carmel and
any applicable state, and/or federal requirements.
Additional information and a sample inspection checklist are available in Appendix B. Checklists
should, at a minimum, address the items identified in this document.

Tools Required:
• Placement Rope • Utility razor knife
• Level • Boat/Raft/Swimsuit
• Small stone or gravel • Shovel
• Rake • Flathead screwdriver
• Permanent Marker • Coast Guard -approved life jacket
STEP ONE: Select a Location for the Aeration Cabinet
• Locate cabinet on a solid surface with adequate strength for the weight of the unit.
• Locate cabinet away from irrigation sprinklers.
• Cabinet must always remain above the high water mark.
* Attention: For airline that runs longer than 100', connector kits are required (sold separately), See Page 9.
If a power source is available near the pond's If a power source is not available near the pond's
shore, locate the cabinet at the pond's edge for shore or you would prefer to install the cabinet
quicker installation. in another location, install Direct Burial Airline(s)
(sold separately) from the cabinet's location to
the pond's edge.
STEP ® Prepare the Ground Surface and Place the Cabinet
1. Place the cabinet on the ground in the selected location and mark
an area 6" wider than the base of the cabinet on all sides.
Use a single airline from cabinet to shoreline
with valves at pond's edge,
Learn about installing an optional
Remote Manifold Kit online at
airmaxeco.com/RemoteManifold
2. Move the cabinet and remove the sod from the area, filling in with
small stone or gravel. This allows for a firm base for the cabinet and
for drainage. Open the aeration cabinet by unscrewing the 4 lobed
thumb screws. Gently lift the cabinet lid and lay on its side next to
the base.
3. Place the cabinet onto the stone base and use your level to make
sure the cabinet is sitting secure and level.
THREE:STEP Excavate Trench and Place Airline(s)
1. Using your shovel, dig a trench from the cabinet to the pond's edge. This trench
should be a minimum depth of 8" to protect the airline. We recommend having utility
lines marked before you begin digging.
2. Place airline into the trench from the aeration cabinet to the pond's edge.
Option A:
Use EasySetTM weighted airline. There must be a separate run of airline for each
diffuser that will be installed. Leave remaining airline coiled at the pond's edge.
Option B:
Use Direct Burial airline. There must be a separate run of airline for each diffuser that
will be installed. Join multiple sections of direct burial airline using 5/8" connector kits.
First, slide two hose clamps onto one section of airline. Next insert the 5/8" insert
adaptor half way into one section of airline and then insert into next the section of
airline. Using a flathead screw driver, secure one of the hose clamps onto each half of
the insert adaptor (see image on the left).
Option B with Remote Manifold: Use 1" Direct Burial Airline or PVC
Pipe. Only 1 run of airline is required from the cabinet location to the pond's edge.
See Remote Manifold Kit Manual or watch the installation video at
airmaxeco.com/RemoteManifold for more information.
STEP FOUR: Connect Airline(s) to the Compressor Manifold
FIVE:STEP Partially Backfill Airline Trench
Attention: For ponds deeper than 21' deep, a Deep Water
Kit (Sold Separately) must be installed before continuing
with installation.
Option A & B:
(this step is not required if a Deep Water Kit is installed)
Slide a hose clamp onto the airline and insert a 3/4" MPT to 3/8 (or 5/8") Insert
Reducer to into the airline, securing with a hose clamp. Next, hand tighten to one of
the quick disconnect flex tubes coming from the compressor manifold. Repeat for
each diffuser line.
Option B with Remote Manifold:
Refer to the Remote Manifold Kit Manual or watch the installation video at
airmaxeco.com/RemoteManifold for more information.
Backfill the airline trench in a few areas to temporarily keep the airline in place until
installation is complete,
STEP ® Connect Weighted Airline for Diffusers
SEVEN:STEP Connect ProAirTm Diffusers
EIGHT:STEP Start the Aeration System
NINE:STEP Install the ProAirTm Diffusers
I
Unroll the EasySetTM weighted airline and remove any kinks or twists, Join enough
sections of weighted airline, using 3/8" or 5/8" connector kits, so that the airline can
rest on the bottom of the pond, from the pond's edge out to the planned location for
each diffuser. For option B installations, connect the weighted airline to the direct
burial airline or Remote Manifold Kit at the pond's edge.
Note: Diffusers should be placed equally apart or in areas of low water movement for
optimum performance. If you need help choosing the correct location for your diffusers,
please contact Airmax® or your local dealer.
See the ProAir'rm Diffuser Manual for assembling and connecting the diffusers.
PS10 Systems: Plug the compressor and cooling fan into the power control outlet
inside of the cabinet. Plug the power control outlet into a GFCI power outlet.
PS20, PS30, PS40, PS80 Systems: Plug the compressor into the power control
outlet inside of the cabinet. Ensure the power switch is in the "ON" position, Plug the
power control outlet into a GFCI power outlet.
Installing Diffusers from a Boat/Raft: Have one person on shore guiding the
airline as a second person uses a boat or raft, extend the airline out to the area of
the pond that the diffuser will be located. Gently release the diffuser into the water.
Repeat until all diffusers are in position.
Installing Diffusers from Shore:
For smaller ponds you may choose to install the diffusers from shore. Have one
person guide the airline while another walks around the pond with the diffuser. Then
thread nylon rope through the diffuser manifold. Use the nylon rope and airline to
gently guide the diffuser into place. Once set, release one side of the nylon rope and
pull to shore. Repeat until all diffusers are in position.
STEP ® Adjust Airflow
ELEVEN:STEP Mark Pressure Gauge
Bubbles should be noticeable on the pond's surface from the diffuser locations.
When more than one diffuser is installed, adjust the airflow valves on the
compressor manifold (For Option B with Remote Manifold, do this step at the remote
manifold). Once an adjustment is made you may need to wait several minutes to see
the results at the diffuser location(s).
Note: Deeper placement of diffusers and longer runs of airline will require more flow.
Using a permanent marker, mark the current pressure gauge reading. During regular
maintenance if the reading is above or below this mark, it may indicate that the system
requires maintenance.
STEP TWELVE: Secure Cabinet & Prepare for Start -Up
Secure the aeration cabinet lid with the 4 lobed screws. You can also secure the
cabinet to prevent unwanted guests with the included Cabinet Lock Kit. Simply replace
2 lobed screws with 2 hex screws and use the hex tool to secure into place. Complete
backfill on airline trenches and level with a rake. Complete installation by reviewing and
following the Initial Start -Up Procedure in Section 3.
®The circulation of poor quality, low oxygen, deep water to the pond's surface can in-
troduce harmful gases and by-products into the previously healthy upper regions of
the water column. These by-products can make the upper regions unfit for aquatic
life and could result in fish -kill.
Initial Start -Up Procedure To Prevent Fish -Kill:
Follow this procedure anytime system has been shut-off for an extended period of
time.
Day 1: Run system for 30 minutes; turn system off for remainder of day.
Day 2: Run system for 1 hour; turn system off for remainder of day.
Day 3: Run system for 2 hours; turn system off for remainder of day.
Day 4: Run system for 4 hours; turn system off for remainder of day.
Day 5: Run system for 8 hours; turn system off for remainder of day.
Day 6: Run system for 16 hours; turn system off for remainder of day.
Day 7: Begin running system 24 hours/day, 7 days/week.
Summer Operation
To reduce the risk of fish kills in hot summer months and for optimum aeration
benefits, Airmax® Aeration Systems should run continuously throughout
the summer.

Winter Operation
Owner assumes all responsibility for operating Airman' Aeration System during
winter months. Operating in freezing conditions on an ice -covered pond will
cause large open water areas at diffuser sites. Ice thickness around open areas
will be much thinner than the surrounding areas. Airmax® strongly recommends
that "Danger - Thin Ice" be posted at frequent intervals around pond.
If you choose to turn your system off for the winter, do the following:
• Unplug your aeration system.
• Disconnect compressor flex-tube(s) from airline(s).
• Cover airline ends with the included winterization caps to prevent debris from
entering airline.
• Move cabinet and compressor inside to keep dry.
• If operating during the winter season, condensation could cause airlines to
freeze. If so:
• Use 1 cup isopropyl alcohol in the airline running out to each plate.
• Turn on compressor to push through line and free any ice blockage.
Is
Airmax® Aeration Systems are designed for low -maintenance and require minimal
scheduled maintenance. Cabinet inlets and outlets should be kept free of debris and
weed growth allowing normal ventilation.
• Always unplug system before performing any maintenance or troubleshooting.
• Always unplug system and refer servicing to a qualified electrician when: cord is
damaged or frayed, compressor, power control, compressor fan, or other electrical
components are producing unusual noises or odors.
• Always use parts that are supplied or approved by Airmax®, Inc. Use of other parts
may result in poor performance and could create a hazardous situation.
"Local environmental conditions may require more frequent maintenance.
WARNING: Compressors are equipped with a thermal overload switch. If temperature
becomes high enough to trip the overload, the compressor will shut down. It will then
automatically start up when temperature decreases as long as power is applied.
EVERY 3-6 MONTHS —Air Filter: Clean/replace air filter.
Cooling Fan: Check to ensure cooling fan is operating. Hot air should be pulled from the cabinet, not blowing
Pressure Gauge: Mark pressure gauge upon initial start up. Check to verify pressure has not significantly
risen above or dropped below initial reading. Normal operation will range between 5-10psi.
Pressure Relief Valve: Check to ensure air is not escaping from valve and replace if needed.
EVERY 1248 MONTHS — Maintenance Kit: It is recommended to install a maintenance kit every 12-18
months to ensure optimum performance.
EVERY 24-36 MONTHS — Membrane Sticks: We recommend inspecting and/or cleaning the membrane
diffuser sticks every 24-36 months, or anytime the pressure gauge reading is significantly higher than normal
or there is a reduction in bubbles from the diffuser. To clean, use Airmax® Fountain & Aeration Cleaner

Maintenance
Cleaning
The Cascade Separator'" system should be inspected at regular
intervals and maintained when necessary to ensure optimum
performance. The rate at which the system collects sediment
and debris will depend upon on -site activities and site pollutant
characteristics. For example, unstable soils or heavy winter sand-
ing will cause the sediment storage sump to fill more quickly but
regular sweeping of paved surfaces will slow accumulation.
Inspection
Inspection is the key to effective maintenance and is easily per-
formed. Pollutant transport and deposition may vary from year
to year and regular inspections will help ensure that the system
is cleaned out at the appropriate time. At a minimum, inspec-
tions should be performed twice per year (i.e. spring and fall).
However, more frequent inspections may be necessary in climates
where winter sanding operations may lead to rapid accumula-
tions, or in equipment wash -down areas. Installations should also
be inspected more frequently where excessive amounts of trash
are expected.
A visual inspection should ascertain that the system components
are in working order and that there are no blockages or obstruc-
tions in the inlet chamber, flumes or outlet channel. The inspec-
tion should also quantify the accumulation of hydrocarbons,
trash and sediment in the system. Measuring pollutant accumu-
lation can be done with a calibrated dipstick, tape measure or
other measuring instrument. If absorbent material is used for
enhanced removal of hydrocarbons, the level of discoloration of
the sorbent material should also be identified during inspection.
It is useful and often required as part of an operating permit to
keep a record of each inspection. A simple form for doing so is
provided in this Inspection and Maintenance Guide.
Access to the Cascade Separator unit is typically achieved through
one manhole access cover. The opening allows for inspection and
cleanout of the center chamber (cylinder) and sediment storage
sump, as well as inspection of the inlet chamber and slanted
skirt. For large units, multiple manhole covers allow access to the
chambers and sump.
The Cascade Separator system should be cleaned before the level
of sediment in the sump reaches the maximum sediment depth
and/or when an appreciable level of hydrocarbons and trash has
accumulated. If sorbent material is used, it must be replaced
when significant discoloration has occurred. Performance may be
impacted when maximum sediment storage capacity is exceeded.
Contech recommends maintaining the system when sediment
level reaches 50% of maximum storage volume. The level of
sediment is easily determined by measuring the distance from the
system outlet invert (standing water level) to the top of the sedi-
ment pile. To avoid underestimating the level of sediment in the
chamber, the measuring device must be lowered to the top of
the sediment pile carefully. Finer, silty particles at the top of the
pile typically offer less resistance to the end of the rod than larger
particles toward the bottom of the pile. Once this measurement
is recorded, it should be compared to the chart in this document
to determine if the height of the sediment pile off the bottom of
the sump floor exceeds 50% of the maximum sediment storage.
Cleaning of a Cascade Separator system should be done during
dry weather conditions when no flow is entering the system. The
use of a vacuum truck is generally the most effective and con-
venient method of removing pollutants from the system. Simply
remove the manhole cover and insert the vacuum tube down
through the center chamber and into the sump. The system
should be completely drained down and the sump fully evacu-
ated of sediment. The areas outside the center chamber and the
slanted skirt should also be washed off if pollutant build-up exists
in these areas.
In installations where the risk of petroleum spills is small, liquid
contaminants may not accumulate as quickly as sediment. How-
ever, the system should be cleaned out immediately in the event
of an oil or gasoline spill. Motor oil and other hydrocarbons that
accumulate on a more routine basis should be removed when an
appreciable layer has been captured. To remove these pollutants,
it may be preferable to use absorbent pads since they are usually
less expensive to dispose than the oil/water emulsion that may be
created by vacuuming the oily layer. Trash and debris can be net-
ted out to separate it from the other pollutants. Then the system
should be power washed to ensure it is free of trash and debris.
Manhole covers should be securely seated following cleaning
activities to prevent leakage of runoff into the system from above
and to ensure proper safety precautions. Confined space entry
procedures need to be followed if physical access is required.
Disposal of all material removed from the Cascade Separator
system must be done in accordance with local regulations. In
many locations, disposal of evacuated sediments may be handled
in the same manner as disposal of sediments removed from catch
basins or deep sump manholes. Check your local regulations for
specific requirements on disposal. If any components are dam-
aged, replacement parts can be ordered from the manufacturer.

Comments
1.The depth to sediment is determined by taking a measurement from the manhole outlet invert (standing water level) to the top of the sediment pile.
Once this measurement is recorded, it should be compared to the chart in the maintenance guide to determine if the height of the sediment pile off
the bottom of the sump floor exceeds 50% of the maximum sediment storage. Note: to avoid underestimating the volume of sediment in the cham-
ber, the measuring device must be carefully lowered to the top of the sediment pile.
2. For optimum performance, the system should be cleaned out when the floating hydrocarbon layer accumulates to an appreciable thickness. In the
event of an oil spill, the system should be cleaned immediately.
