→Chamber Installation
The installation of infiltration chambers requires the placement of manifolds, the chamber components themselves, and perimeter stone. As such, the construction of infiltration chambers is a multi-faceted process.

Construction Steps:
Construction Steps:
#Install chamber manifolds to the top of the storage reservoir.
#Install chamber manifolds to the top of the storage reservoir.
*Uneven perimeter stone – Perimeter stone must be applied such that the depth of stone on one side of the chamber is not unacceptably higher than the other. Refer to design details.

*Incorrect inlet elevation – For applications where infiltration chambers overflow into a sewer, it is important that the top of chamber is positioned at an elevation below the lowest invert of the sewer. Otherwise, only part of the chamber volume can be utilized.

This is because the chamber’s capacity should be fully utilized before runoff is allowed to travel farther downstream.
