Reducing Highway Runoff Pollution - sustainable design and maintenance of stormwater treatment facilities

Dokumentbeteckning: 2018:155

Management practices for handling highway runoff differ between the various European national road administrations. These differences manifest themselves in different approaches related to planning, construction and operation of runoff treatment facilities. For example, Sweden, Norway and Germany, use different standard guidelines when managing stormwater. Proprietors, owners, consultants and building contractors involved in design and construction of treatment facilities are accountable for meeting the requirements set by the national road administrations or by the national environmental authorities.

With the aim of compiling current practice and knowledge of stormwater best management practices (BMPs) the Swedish Transport Administration (STA), the Norwegian Public Roads Administration (NPRA) and the Danish Road Directorate (DRD) initiated the collaborative project “Reducing Highway Runoff Pollution” (REHIRUP). This project aims to provide a basis for design, operation and management of environmentally safe and cost-effective stormwater BMPs. Thereby, REHIRUP endeavours to contribute to the overall goal of improved pollutant retention efficiencies, enhanced degradation of organic pollutants,
optimised multiple use of the land utilised for runoff management, and an overall better utilization of resources. 

One of the project objectives is to provide recommendations for maintenance of future BMPs such as settling ponds, subterranean stormwater storage facilities and filters, and thereby improve road runoff management in an environmentally and economically sustainable way. 

This report summarizes outcomes of two work packages (WPs) of the REHIRUP project, namely Maintenance (WP2) and Sustainable design (WP4).
