Abstract
The performance of three different Sustainable Urban Drainage Systems (SUDS) in East Scotland is outlined in this paper. These systems are a porous pavement at the Royal Bank of Scotland (RBS) in Edinburgh, a roadside filter drain along Lang Stracht Aberdeen (LSA) and regional SUDS at Dunfermline Eastern Expansion (DEX). The systems' performance in attenuating flows proved to be satisfactory. This is shown by consideration of percentage runoff, initial runoff loss, monthly outflow reduction of rainfall and lag time. The systems were found to perform well in attenuating pollutant peaks. This is investigated through comparison of inflow and outflow concentrations as well as comparison with Environmental Quality Standards (EQS). Samples were analysed for standard sanitary parameters at all sites in addition to heavy metals and hydrocarbons at RBS. A computer model was developed to simulate outflow from the porous pavement at RBS and the filter drain at LSA. The modelling results show an excellent prediction of the outflow behaviour from the porous pavement and preliminary simulation show reasonable agreement with the outflow from the filter drain. Research at LSA and DEX is ongoing.
