| The
Houghton-Hancock plant is designed to
treat an average flow of 3.1 mgd
(receiving and average 2.2 mgd), while
serving a population of nearly 14,000 in
and near the communities of Houghton and
Hancock. Almost all of the flow comes
from domestic and commercial sources.
The plant does an outstanding job of
pollutant removal consistently removing
98% of the biochemical oxygen demand and
suspended solids, and more than 95% of
the phosphorus from the incoming
wastewater. Major treatment processes
include preliminary treatment, primary
clarification, phosphorus removal,
biological treatment utilizing the
activated sludge process, final
clarification, and ultraviolet
disinfection prior to discharge to
Portage Lake, a part of the Keweenaw
Waterway, which flows into Lake Superior
at Keweenaw Bay. Residuals are
anaerobically digested, dewatered by
belt filter presses, and applied as
biosolids fertilizer to the Torch Lake
Superfund Site to support vegetation.
