The ESTRUS Project (Enhanced and Sustainable TReatment for Urban Storm water) within the LIFE Environment Programme aims at demonstrating the suitability and costeffectiveness of catch basin treatment solutions for storm water runoff in harbor areas and production sites. In the present paper the results of the first phase of the project including the hydraulic performance tests of different inlet treatment devices and the preliminary results of the monitoring campaign for the field tests are presented. In order to evaluate the influence of the hydraulic behavior on the devices treatment efficiency, the experimental results are here interpreted through a simple pollution generation/wash-off model. The model has been applied to the IPLOM S.p.A. monitoring site for a long term simulation over a period of 18 years for two different treatment devices. Results are shown in terms of the treatment efficiency, total influent mass of suspended solids entering the catch basin filters and non treated mass due to hydraulic failure.

Abstract
The ESTRUS Project (Enhanced and Sustainable TReatment for Urban Storm water) within the LIFE Environment Programme aims at demonstrating the suitability and costeffectiveness of catch basin treatment solutions for storm water runoff in harbor areas and production sites. In the present paper the results of the first phase of the project including the hydraulic performance tests of different inlet treatment devices and the preliminary results of the monitoring campaign for the field tests are presented. In order to evaluate the influence of the hydraulic behavior on the devices treatment efficiency, the experimental results are here interpreted through a simple pollution generation/wash-off model. The model has been applied to the IPLOM S.p.A. monitoring site for a long term simulation over a period of 18 years for two different treatment devices. Results are shown in terms of the treatment efficiency, total influent mass of suspended solids entering the catch basin filters and non treated mass due to hydraulic failure.
