==Overview==

[[Infiltration chambers]] include a range of proprietary manufactured, modular structures installed underground (embedded in clean, crushed angular [[stone]]) to create large void spaces that temporarily store and infiltrate runoff into the underlying native soil. Typically installed under parking or landscaped areas, they can be used in various configurations. They are well suited to sites where available land area is limited, or where it is desirable for the facility to have a minimal surface footprint. They can be designed with enough load bearing capacity to support the weight of structures above them, meaning that they can be installed below parking lots, sports fields, etc.

STEP has prepared life cycle costs estimates for infiltration chamber systems located on highly permeable native soil (Full Infiltration design), and moderately permeable native soil (Partial Infiltration design) scenarios for comparison. Cost estimates are based on a 2,000 m² asphalt drainage area, runoff control target of 25 mm depth and 82 and 163 hour drainage periods for Full and Partial Infiltration Design scenarios respectively, which can be viewed below. To generate your own life cycle cost estimates customized to the development context, design criteria, and constraints applicable to your site, access the updated [https://sustainabletechnologies.ca/lid-lcct/ LID Life Cycle Costing Tool (LCCT) here].
