The performance and effectiveness of geotextiles within permeable pavements for treating concentrated storm water

Abstract

One of the guiding principles of sustainable urban drainage systems (SuDS) is centred on mitigating adverse effects of urban stormwater runoff such as increased urban flooding and deteriorating receiving water quality. SuDS such as permeable pavements are commonly perceived as an effective source control measure to reduce stormwater flows and pollution loads. However, there are limited studies aimed specifically at quantifying the effectiveness of utilising permeable pavements with geotextiles as a pollutant source control measure. This research examines the effectiveness of permeable pavements in treating concentrated urban runoff for water reuse and recycling, assessing the presence of geotextile membranes within the permable pavement structures in terms of its efficiencies for removing water pollutants. The main aim of this research assesses and quantifies the performance of permeable pavements in reducing stormwater pollution loads for UK conditions. Environmental monitoring of flow and water quality were conducted within the sampling regime from an experimental setup of pavement
