1.0 Introduction
The City of Carmel has adopted a policy in compliance with the National Pollutant
Discharge Elimination System (NPDES) stormwater permit to control and improve the
water quality of stormwater runoff. The water quality management program is based on
the performance of approved structural Best Management Practices (BMP) to remove
80% of total suspended solids (TSS) from the first 1-inch of storm water runoff. Design
requirements and parameters may be found in the City of Carmel Stormwater Technical
Standards Manual.
1.1 Project Description
The Franciscan Orthopedic Center of Excellence site contains a new combined medical
office building (MOB) and hospital is proposed on the 10.8 south parcel. The
MOB/Hospital is connected to a four-story parking garage structure via an above ground
pedestrian connector. The pedestrian connector is located above grade to provide an
enclosed connection between the MOB/hospital and the parking garage. There is an
alternate exterior fitness and rehab area including batting cage, synthetic turf, and half
basketball and tennis area. The connector spans the gas main that bisects the site.
Construction shall include the new buildings, a proposed alternate 69 -space surface
parking lot north of the garage structure for valet parking, staff parking south of the
MOB/hospital building, as well as interior drives and pedestrian connectivity. Additionally,
the project will include provision of utilities including gas, electric, and data and new
connection for water and service and sanitary laterals. To address stormwater
management, the site includes a series of hydrodynamic separators and underground
detention prior to discharging to the regulated drain to the east.
For the proposed project, water quality treatment is provided for the non-direct discharge
stormwater runoff. A treatment train is provided via stormwater runoff being treated via a
structural BMP hydrodynamic separator prior to discharging to the isolator row of the
underground detention system. The isolator row is a water quality feature of the
Stormtech Chamber underground detention system. There are four Aqua-Swirl water
quality units proposed for the site. The following is a summary of the water quality for the
site:

1.2 Purpose and Performance
In order to achieve the 80% target removal rate of TSS from the stormwater runoff
associated with the proposed improvements, flow through BMPs were selected based on
the physical site characteristics, cost, and the ability to meet the water quality treatment
flow rate to be treated per City of Carmel requirements. The benefits of this type of BMP
is a very high pollutant removal rate and ability to address floatables.
The proposed new BMPs are located on the downstream end of the storm sewer network
prior to discharging runoff to the underground detention system which has a water quality
component via the isolator row. The two treatment methods provide a treatment train.
The proposed BMPs have been sized to treat the runoff from the proposed building and
adjacent hardscape and landscape areas for the site according to the City of Carmel
Stormwater Technical Standards Manual. (See Calculations and Exhibits in the Drainage
Report).
2.0 Water Quality Maintenance
As part of the Water Quality program, the City of Carmel also requires a maintenance and
inspection program by the Owner for each type of BMP.
2.1 Maintenance and Inspections
Routine inspections, maintenance, and the costs necessary for the maintenance and
repair of the BMPs are the responsibility of the owner. The following are the
recommended inspection items and timeframes for the Aqua Swirl units.
Inspection Frequency: The manufacturer recommends quarterly inspections;
however, City of Carmel Engineering Department
requires annual inspection reports to be submitted to the
city, in the same month as the initial inspection.

Maintenance and Inspections (Mechanical BMP- Aqua Swirl Units)
Maintenance and Inspections (Isolator Row as part of Underground Detention)
Inspection Item:
Sediment – Sediment is to be removed when inspection
reveals a top of sediment depth within 6 in. of the dry-
weather water surface elevation in the structure. Sediment
depths can be easily determined by measuring the distance from
the top of the manhole to the dry water surface elevation and then
measuring the distance from the top of the manhole to the top of
the sediment pile. This can be done with a steel tape or stadia
rod. The system should be pumped clean using a high velocity
vacuum truck.
Free-floating oil and floatable debris – use a high velocity
vacuum truck to clean the pollutants. After recording the
measurements on the Inspection Data Sheet (attached in
Appendix B), the vacuum hose is lowered through the access
opening and the floating debris. The oil may be best removed by
using an absorbent pad. Usually, confined space entry can be
avoided by inspecting from the manhole entrance and cleaning the
system by using a vacuum hose.
Inspection Item:
Sediment – Sediment is to be removed when inspection
reveals a top of sediment depth is 3 in. at bottom of structure.
Sediment depths can be easily determined by measuring the
distance from the top of the manhole to the dry water surface
elevation and then measuring the distance from the top of the
manhole to the top of the sediment pile. This can be done with a
stadia rod. The system should be cleaned using a JetVac process.
Inspect diversion manhole and outlet manhole. Vacuum manhole
base and sump as required.
Floatable debris – use a flashlight and mirrors to inspect the
interior of the isolator row for floatable debris.
Inspect down isolator row through the outlet pipe. Mirrors on poles
or cameras may be used to avoid confined space entry.
As needed, clean isolator row with JetVac process

Floatable Debris and Oil
1. Remove manhole lid to expose liquid surface of Aqua-Swirl
TM.
2. Remove floatable debris with basket or net if any is present.
3. If a hydrocarbon spill has occurred, (e.g. more than a sheen of oil or gas is present) the system should be cleaned immediately
(see "Cleaning" Figure 3).
Note: Water in an Aqua-SwirlTM can appear black like oil due to the dark body of the surrounding structure. Oil appears
darker than water in the system and is usually accompanied by debris (e.g. Styrofoam, etc.) with obvious signs of oil stains.
The depth of oil can be measured with an oil/water interface probe, a stadia rod with water phylic paste,
a coliwasa, or by simply collecting a representative sample with a jar attached to a rod.
4. If hydrocarbon absorbant floc or pads are used, these should be inspected to determine whether they are loaded with
hydrocarbons. This will be indicated by a dark colaration of the pad or floc. Pads and/or floc should be removed and
disposed of in accordance with City of Indianapolis and any applicable state and/or federal laws if they contain hydrocarbons.
Sediment Accumulation
Lower a dipstick tube equipped with a ball valve (e.g. Sludge Judge or similar device) into Aqua-SwirlTM through the service access provided.
Measure the depth of the sludge. At a maximum, the sludge should not exceed 36" depth before maintenance. See Figures 1 and 2.

Diversion Structures
If an external diversion structure is present on the site, this should be inspected for the following items.
1. Inspect weir or other structure for structural decay or damage. Weirs are more susceptible to damage than off-set piping and should
be checked to confirm that they are not crumbling or decaying.
2. Inspect diversion structure and by-pass piping for signs of structural damage or blockage from debris or sediment accumulation.
3. Measure elevations on diversion weir or piping to ensure it is consistent with site plan design.
4. Inspect downstream structure in diversion system for signs of blockage or structural failure.
Remove sediments, oils and other
floatable pollutants with a vactor. Dispose of all waste in
accordance with City of Indianapolis and any applicable state,
and/or federal requirements.
Oil should be pumped and removed with any liquids and
sediments that have been trapped in the system.
These liquids should be taken to an industrial waste water
treatment facility for treatment. Liquids and solids pumped from
the AquaSwirlTM should not be dumped back into the
stormwater system or into a sanitary sewer.
