Abstract:

To reduce turbidity in sedimentation-basin discharge, Anchorage, Alaska, is experimenting with constructed wetlands to augment storm-water discharge treatment from several storm-drain systems. The largest project�the 5.7 ha (14 ac) South Anchorage Snow Disposal and Sedimentation Basin�will treat discharges from more then 445 ha (1,100 ac) of residential, commercial, and industrial drainage and runoff from a 7 ha (17 ac) snow-disposal site. The project will play a significant role in the city's permit-compliance strategy.
