Abstract
This study described the significance of a multi-functional constructed wetland implemented to restore a degraded urban waterway in Western Australia. The restoration aimed to improve urban liveability by reducing stormwater nutrients and providing local amenity. The wetland was constructed as a multi-compartment surface flow and laterite-based subsurface flow system, with
the potential for operation of a recirculation scheme and ground water top-up during low water flows in summer. The wetland performance was assessed by comparing N and P attenuation during high and low flow conditions from 2009 to 2015. The performance depended on hydraulic retention time, varying from approximately a 41% TN and 66% TP loads reduction during storm events, increasing up to 62% TN and 99% TP during low flow and summer recirculation periods. The design proved to be not only highly effective at reducing nutrient loads, but also improved the ecological services of the urban waterway by providing a diverse area for habitat and recreational activities.
