A NEW TYPE OF RAINWATER RESERVOIR: POROUS PAVEMENTS

UN NOUVEAU TYPE DE RESERVOIR POUR LES EAUX PLUVIALES: LA CHAUSSEE POREUSE

An account is given of the use of porous pavement material to drain water from the road surface and intercept that from adjoining properties. Situated in reze-les-nantes, France, the road runs along a valley basin and at points is subject to overflowing. To prevent the problems of surface run-off posed by impermeability of the ground due to urbanisation the reze communal authorities designed a structure to temporarily contain water in a reservoir of porous materials. The final design produced in collaboration with the central laboratory of bridges and roads is shown in cross-section. The reasons for choosing a geotextile at the formation level in preference to an impermeable membrane are discussed. The costs of the elements of the structure are listed and compared with a conventional pavement. A 5% saving in costs was calculated to which could also be added advantages associated with the reduction in the flow of water downstream. Also experienced were an elimination of spray from vehicles and a reduction in noise levels.
