The Ohio Division,Champion Papers, Inc. , is a paper-making and coating mill located on the west bank of the Miami River in the middle of Hamilton, Ohio. The primary concern of this paper is with the waste treatment
plant placed in operation at the Ohio division in August 1961.
SEWER SYSTEMS
The gradual growth of the Ohio division resulted in a gradual growth of
the sewer system so that at one time there were 24 separate sewers which
could -- and sometimes did -- discharge directly into the river at the mill
site.
To further complicate the sewer problems, it was found that the plans
for some of them were lost in the great flood of the Miami River in 1913 and
it, therefore, was necessary to use dyes to trace the systems back to their
origins. Sewer tracing can be a very tiring job, particularly when some of
the sewers turn out to be for storm drainage and require barrels of water in
inaccessible places before they will start to flow. Advantage was taken of
rainfall whenever possible, but even so it was a wet, time-consuming task.
After the remapping of the sewer system, planning for a modernization program which would eventually provide three systems for three types of waste
was started.
The city of Hamilton built its sewage treatment plant about the same
time as the study took place and asked that the sanitary sewage from the
waste treatment plant be segregated from all other wastes for discharge to,
and treatment by, the city. The paper plant has over one and one-half mil-
lion sq ft of floor space and a correspondingly large number of sources of
sanitary sewage. The segregation of sanitary sewage is expected to be virtually completed with the installation of one more sewer this year. When
installation is completed, all of the sanitary sewage will be treated by the
city, with Champion paying for this service at rates established by the city
council.
While the sanitary sewage was segregated, a storm-sewer system was also
evolved using many of the old sewers which still discharge directly into the
river at the mill. One of these storm sewers, through some ancient complicated arrangements, formerly carried sanitary sewage from part of the city
above the mill. In order to change this to a storm sewer, it was necessary to
intercept the sanitary sewage above the mill and reroute it into one of the
new sanitary sewers.
The industrial waste sewer system is the most complicated and important
system. When the sewer survey was completed, it was found that the industrial wastes were  mainly concentrated  in seven sewers,  but that sanitary
