<br />A 21-inch effluent pipe will convey the trea!ed wastewater to the Rocky River.
<br />While discharge modeling has determined that reaeration of the effluent is not
<br />required, the discharge line will be stepped in drop manholes to provide
<br />additional aeration to the effluent as an additional low cost reaeration step. A
<br />disoh~rte header with effluent por~s will be laid perpendicular to shore
<br />extending into Rocky River to diffuse the effluent.
