An infiltration box (also called stormbox) is a plastic box used to manage and attenuate rainwater.
Contents
Overview
The box temporarily intakes water to avoid floods or water reservoir. To create an infiltration system, an assembly of hundreds or more infiltration boxes are necessary. In case of heavy rain if the water has no more to channel the flow in pipelines, infiltration boxes allows the water to infiltrate and attenuate water flows: first, water is stored temporarily in the weft of a box so it does not reach immediately the pipeline system; second, water is slowly release so no flooding occurs.
Infiltration boxes, when newly installed, allow reducing the diameter of pipes and facilitating infiltration in the ground of rainwater to feed the water table to avoid waste of rain water . Infiltration boxes have a designed lifetime over 50 years. Some of the main producers are Pipelile and Wavin.
Uses
In most urban areas, storm water piping systems are overloaded due to the increasing pace of development and construction. In many cases, renewing of existing pipe systems or installation of new ones is impossible for cost reasons and/or because the construction work would interrupt vital communications. In addition, old or incorrectly sized pipe networks cannot be sometimes capable of handling the quantities of water that arise. These networks might therefore lead to uncontrolled storm water which then finds its own way to escape from run-off areas in the form of streams and floods.
Materials
The material with which an infiltration box is generally manufactured is Polypropylene (PP).
