Description The city of Black Diamond in King County presently operates a wastewater treatment plant (WTP) which discharges to a natural wetland. Discharge of effluent to the marsh was designed to utilize the natural processes in order to remove nutrients (nitrogen and phosphorus). The wetland drains into Rock Creek, which in turn discharges to Lake Sawyer. The WTP had been determined to have failed to meet design removals of phosphorus. Diversion of the WTP discharge from the Rock Creek system is currently planned.
