The ESTRUS project: performance of catch basin treatment devices in the field

During the period 2006-2008, the ESTRUS Project (Enhanced and Sustainable TReatment for Urban Storm water) within the LIFE Environment Programme aimed at demonstrating the suitability and cost-effectiveness of catch basin treatment solutions for storm water runoff in harbour areas and production sites. The project consisted of a preliminary laboratory study (not described in this paper), and a following field implementation study. For the latter, a monitoring campaign was carried out at four pilot sites in the territory of the Province of Genoa (two port terminal sites and two production sites). Quali-quantity data were collected at the outlet section of the investigated storm water drainage networks, with and without treatment systems installed directly into the catch basin inlets, in order to assess the field performance of the catch basin treatment devices. This document focuses in particular on the treatment efficiency of suspended solids, hydrocarbons and heavy metals, which represent the main pollutant constituents associated with storm water runoff at the investigated experimental sites.
