ARC 18 Chamber Material High Density Polyethylene Connections Built in latch Bottom width (mm) Height (mm) Length (mm) End Plates Snap on Strength (IAPMO rating) H Authorization Requested The applicant sought authorization for use of the Infiltrator Systems Inc. ARC 18 Chamber System as an alternative to the construction of stone and distribution pipe in absorption trenches and in filter beds as required by Section 8.7. of Division B of the Building Code. The applicant requested that the Infiltrator Systems Inc. ARC 18 Chamber System be used to replace stone and distribution pipe in absorption trenches and filter beds that are gravity fed, dosed, and pressurized. This Authorization supersedes BMEC BioDiffuser : ARC 18 Chamber System, which was valid, and authorized for use from August 7, 2008 to August 1, Note 1: For the purposes of this authorization, dosed means a system in which effluent is pumped to the leaching bed either by pump or siphon, but the effluent is not pressurized within the leaching bed. 5. Assessment Reports and assessments provided by the applicant show that if the Infiltrator Systems Inc. ARC 18 Chamber System is designed, performance tested, installed and maintained in accordance with the limitations in the manufacturer's instructions and the conditions stated in this authorization, a level of performance will be provided as required by the Building Code, for absorption trenches in soil, in leaching bed fill or in a filter bed, whether gravity fed, pressurized or dosed.
