ISO/CD TS 4982-2

Plastics piping systems for non-pressure underground conveyance and storage of non-potable water — Arch-shaped, corrugated wall chambers made of PE or PP used for retention, detention, storage and transportation of storm water systems — Part 2: Guidance for structural design of arch-shaped chamber systems

Scope

This document gives guidance on the structural design of plastic underground arch-shaped, corrugated wall chambers conforming to ISO 4982 used in underground systems for retention, detention, transportation and storage of non-potable water (e.g. storm water) under various conditions of loading.
These chambers are intended for buried underground use in landscape, pedestrian or vehicular traffic areas.
The chambers, including integral components, are injection moulded or thermoformed thermoplastics, manufactured from polyethylene (PE) or polypropylene (PP), and are intended to be used as elements in a modular system where the manufacturer has clearly stated in the documentation how the components are assembled to create a complete retention, detention, transportation or storage system.
