Abstract: Operating different stormwater treatment devices in series as a treatment train may remove a wider span of pollutants and hence improve the overall performance of the system. This paper presents results of field tests conducted in Auckland (NZ) of the performance of a stormwater treatment train system. Stormwater runoff from a “Park and Ride” bus station and roadway is treated by series operation of devices including bioretention cells, grassed swales, a manufactured underground filter system and a constructed wetland prior to discharge. Low event mean concentrations of total suspended solids, dissolved and total recoverable copper, dissolved and total recoverable zinc show the site is very clean compared to most urban runoff. Nonetheless, results to date show that the treatment train is effective at water quality control except for total dissolved solids removal.
