This document gives guidance on the structural design of underground modular systems for infiltration,attenuation and storage of surface water under various conditions of loading. The procedures areexplained, with the appropriate variables in the design formulae, and provides graphical information onvehicle surcharge loadings.
These modular systems are constructed from multiple cuboid shaped thermoplastic boxes generally withancillary components such as inlet/outlet connectors, vents, and access/inspection provision. Thisguidance is for the design of modular systems conforming to EN 17152-1.
The boxes, including integral components, are injection moulded, extruded or thermoformedthermoplastics, manufactured from polypropylene (PP) or unplasticized poly(vinyl chloride) (PVC-U),and are intended to be used as elements in a modular system where the manufacturer has clearly statedin the documentation how the components are assembled to create a complete infiltration, attenuationor storage system.
