RE: ACF environmental R-Tank Storm Water Systems
Dear Ms. Petzke:
The City of Indianapolis (the City) Department of Public Works (DPW) thanks you for the
information on the ACF environmental R-Tank Storm Water Systems submitted for review and
possible approval in the Indianapolis Stormwater District. The City’s consultant, DLZ Indiana
LLC (DLZ), has completed their review of the information and submitted their report to DPW
(attached). DPW subsequently reviewed DLZ’s report and has made the following
determination.
Based on this conclusion, the DPW is approving the application of the ACF environmental R-
Tank Storm Water Systems Units R-Tank, R-Tank HD, and R-Tank SD for use within the
district for use on private underground detention and will be considered by DPW project
managers in order to identify on a case by case basis where this product may be best suited,
provided the following criteria are met:
All underground detention facilities shall be designed with a positive gravity outfall or a
certification from a licensed geotechnical engineer confirming that:
• The permeability of the surrounding soils will dissipate water at a rate required
for the detention facility designed
• No adverse impact to any subsurface systems (including septic systems) will be
experienced
• The underground detention facility will not be subject to ground water surcharge
during any time of the year
Any facility that allows infiltration within a “Well-Head Protection Area” needs prior
approval from the Department of Public Works Office of Environmental Services.
Page B 1
If the system is designed to use the storage volume of the stone surrounding the structure,
a 40 percent porosity factor shall be utilized for the surrounding washed #8 stone.
All storm water shall be routed through a Storm Water Best Management Practice (BMP)
meeting City Standards prior to the detention area.
No storm water shall be routed through the ACF environmental R-Tank storm water
detention facility until the BMP is installed and fully functional and all erosion control
measures for disturbed areas are installed to ensure that sediment build-up in the
underground detention storage facility is minimized. The erosion control methods and
BMP’s must be inspected after each rain event and repaired or cleaned when necessary.
The O&M Manual for all BMP’s located prior to the underground detention storage
facility requires the BMP’s to be inspected four times per year and cleaned as necessary
to ensure maximum performance relative to sediment removal.
Underground storage vaults shall be constructed of accepted storm sewer pipe materials
(Section 402), manufactured, tested, and installed according to those guidelines set forth
herein.
The sizing of the plastic chamber system should follow the City of Indianapolis’ Storm
Water Design and Construction Specifications Manual. The chamber storage system is
treated in similar fashion to a detention/retention pond as far as sizing, and therefore such
calculations should be made in the same manner. The actual number of chambers and
configuration of the chambers shall be based on engineer’s specifications and
calculations.
The City thanks you for your interest and looks forward to the application of the ACF
environmental R-Tank Storm Water Systems within the district.
If you have any questions regarding this matter, please contact me at 317-633-4120 or via email
Sincerely,
Rachel Wilson, PE

RE: New Product Review\ HydroStor HS75 and HS180 Chamber Subsurface Stormwater
Strorage Chamber
Dear Mr. Storms:
You have requested formal review of your products “HydroStor HS75 and HS180 Chamber” for
underground storm water detention. The New Products Committee of the Department of Public
Works has recommended approval the HydroStor HS75 and HS180 Chamber. Therefore, these
products have been approved by for use on private development and public projects for
underground storm water detention, provided the following criteria are met:
High Impact Polypropylene or High-Density Polyethylene Plastic Facilities
The chambers’ plastic shall be resistant to environmental stress cracking and maintain
adequate stiffness through the higher temperatures experienced during installation and
service. The chambers shall be designed to exceed the American Association of State
Highway and Transportation Officials (AASHTO) recommended Load and Resistance
Factor Design (LRFD) for earth loads and HS-20 live loads, with consideration for
impact and multiple presences when installed per the manufacturer’s minimum
requirements. The plastic chambers shall have a design life of 75 years, Class 1 and Class
3 Storm Water System.
All underground detention facilities shall be designed with a positive gravity outfall or a
certification from a licensed geotechnical engineer that:
The permeability of the surrounding soils will dissipate water at a rate required
for the detention facility designed
No adverse impact to any subsurface systems (including septic systems) will be
experienced

A maintenance system shall be set up for the chamber storage system. At a minimum,
the system shall be inspected for sediment and debris every three to six months until an
understanding of the operation of the system is obtained. To facilitate cleaning and
inspection, adequate access ports shall be provided into the chamber system.
The HydroStor HS75 and HS180 Chambers have been approved for H20 loads, but may
have limits for heavier loading such as fire truck stations around buildings. Specific
considerations must be part of the engineering design for locations.
If you have any other questions on this issue, please feel free to contact Bill Bowman at
[email protected]. Bill is spearheading the New Products Committee and will be glad to
help you.
