The Filterra unit will filter the runoff as it flows through the growing medium provided in the structure.
The CDS unit provides Water Quality through a vortex that is created by channeling the floes into a
circular motion, allowing sloid to settle out and fall to the containment chamber at the bottom of the unit
and floatables are removed via an `oil. Baffle skirt" built into the structure. There is a flow control riser
installed in a Flow Control Manhole that restricts the release rate of the facility to jurisdictional rates.
An emergency overflow is provided in the structure to allow the larger flow storms to drain out of the
Detention Piping to avoid ponding or surcharging the upstream piping. Once treated the runoff is
conveyed to an existing public storm main.
Inspection/Maintenance Schedule
Each part of the system shall be inspected and maintained quarterly and within 48 hours after each major
storm event. For this O&M Plan, a major storm event is defined as 1.0 inches of rain (or more) in 24

CDS`R' Inspection and Maintenance Guide
�
FDS
Maintenance
The CDS system should be inspected at regular intervals and
maintained when necessary to ensure optimum performance.
The rate at which the system collects pollutants will depend more
heavily on site activities than the size of the unit. For example,
unstable soils or heavy winter sanding will cause the grit chamber
to fill more quickly but regular sweeping of paved surfaces will
slow accumulation.
Inspection
Inspection is the key to effective maintenance and is easily
performed. 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 fime. At a minimum,
inspections should be performed twice per year (e.g. spring
and fall) however more frequent inspections may be necessary
in climates where winter sanding operations may lead to rapid
accumulations, or in equipmentwashdowm areas. Installations
should also be inspected more frequently where excessive
amount of trash are expected.
The visual inspection should ascertain that the system
component are in working order and that there are no
blockages or obstructions in the inlet and separation screen.
The inspection should also quantify the accumulation of
hydrocarbons, trash, and sediment in the system. Measuring
pollutant accumulation can be done with a calibrated dipstick,
tape Treasure 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 idenfified
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.
Access to the CDS unit is typically achieved through two manhole
access covers. One opening allows for inspection and cleanout
of the separation chamber (cylinder and screen) and isolated
sump. The other allows for inspection and cleanout of sediment
captured and retained outride the screen. For deep unit, a
single manhole access point would allows both sump cleanout
and access outside the screen.
The CDS system should be cleaned when the level of sediment
has reached 75% of capacity in the isolated sump or when an
appreciable level of hydrocarbons and trash has accumulated.
If absorbent material is used, it should be replaced when
significant discoloration has occurred. Performance will not be
impacted until 100% of the sump capacity is exceeded however
it is recommended that the system be cleaned prior to that
for easier removal of sediment. The level of sediment is easily
determined by Treasuring from finished grade down to the
top of the sediment 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. Particles at the top of
the pile typically offer less resistance to the end of the rod than
consolidated particles toward the bottom of the pile. Once this
measurement is recorded, it should be compared to the as -built
drawing for the unit to determine weather the height of the
sediment pile off the bottom of the sump floor exceeds 75% of
the total height of isolated sump.
Cleaning
Cleaning of a CDS systems 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 convenient
method of removing pollutant from the system. Simply remove
the manhole covers and insert the vacuum hose into the sump.
The system should be completely drained down and the sump
fully evacuated of sediment The area outside the screen should
also be cleaned out if pollutant build-up exist in this area.
In installations where the risk of petroleum spills is small, liquid
contaminant may not accumulate as quickly as sediment
However, the system should be cleaned out immediately in
the event of an oil or gasoline spill should be cleaned out
immediately. 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 pollutant, it may
be preferable to use absorbent pads since they are usually less
e ensive to dispose than the oil/water emulsion that may be
created by vacuuming the oily layer. Trash and debris can be
netted out to separate it from the other pollutant. The screen
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 also to ensure that proper safety precautions have been
followed. Confined space entry procedures need to be followed
if physical access is required. Disposal of all material removed
from the CDS system should be done in accordance with local
regulations. In many jurisdictions, disposal of the sediment may
be handled in the same manner as the disposal of sediment
removed from catch basins or deep sump manholes.

1. The water depth to sediment is determined by taking two measurements with a stadia rod: one measurement from the manhole opening to the
top of the sediment pile and the other from the manhole opening to the water surface. If the difference between these measurements is less
than the values fated in table 1 the system should be cleaned out. Note: to avoid urderestimatirg the volume of sediment in the chamber,
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 eeent of an oil spill, the system should be cleaned immediately.
