Augmented Rainwater Infiltration & Pollutant Mitigation (ARIPM) Systems for Industrial Stormwater Management

The process of industrial urbanization has significantly transformed the nature of hydrological processes supporting natural phenomena and enhanced the amounts of stormwater runoff, the amount of discharge peaks, and the mobilization of contaminants on impervious industrial surfaces. The traditional drainage models that are mainly used to facilitate quick flow have become ineffective in dealing with the hydrological imbalance and also the loading of contaminants and especially in face of the mounting pressures of the extreme rainfall events caused by climate change. The article focuses on Augmented Rainwater Infiltration and Pollutant Mitigation (ARIPM) systems as a combined stormwater management system to fit an industrial catchment. The main purpose is to assess the hydrological efficiency and the attenuation ability of ARIPM systems based on a synthesis of empirical field research, monitored systems and regulatory performance databases. The analysis is based on the quantitative evaluations of infiltration enhancing and reduction of runoff volume, attenuation of peak flows, and elimination of major industrial stormwater pollutants like total suspended solids, nutrients, hydrocarbons, and heavy metals. The results show that ARIPM systems can always increase infiltration rates and decrease the surface runoff and have significant reductions in the contaminants load using physical filtration, sorption and biogeochemical processes. The variability of the performance is noted in soil conditions, rainfall regimes, and typologies of industrial land-use, which emphasize the significance of the site-specific design and maintenance strategies. The originality of the paper is placing ARIPM systems within the paradigm of a hybrid green-grey infrastructure that is based on the hydrological restoration and the controlled industrial pollutants, which is not always a dominant theme in the study of stormwater. The findings show that ARIPM systems can provide a scalable, robust, and regulatory-compliant solution to enhance industrial stormwater management and increase the urban environment resilience.
