REPORT TO THE GENERAL PURPOSE AND ADMINISTRATION COMMITTEE
MEETING OF APRIL 5, 1983.
REPORT NO. : WD-40-83.
SUBJECT: REPORT ON CORRESPONDENCE FROM THE REGION OF
DURHAM WITH RESPECT TO STORM AND SANITARY
SEWER CROSS-CONNECTIONS IN THE BEAU VALLEY
ESTATES SUBDIVISION IN BOWMANVILLE
RECOMMENDATION:
It is respectfully recommended:
1. That the Region of Durham be advised that the Town
of Newcastle is willing to pay its share of the cost
of eliminating storm sewer house connections to the
sanitary sewers in the Beau Valley Estates
Subdivision in Bowmanville; and,
2. That the Region be further advised that the Town will
only participate in costs at those houses where there
is, in fact, a connecting of the storm to the
sanitary sewer found, rather than on a blanket 50/50
basis; and,
3. That the Region be further advised that the Town will
pay fifty percent (50%) of the investigative work
leading to the program of eliminating the
cross-connections; and,
4. That funds to cover the Town's share of the cost of
correcting the cross-connections (about $10,000) and
for the investigative work (about $3,000) , for the
eleven (11) connections involved, be derived from the

BACKGROUND:
As a result of sanitary sewerage being found at storm sewer
outfalls from the Beau Valley Estates Subdivision in
Bowmanville, the Region of Durham performed an investigation
in the subject area. Approximately, two hundred and
sixty-six (266) homes were dye tested in the area bounded by
King Street East, Simpson Avenue, and Soper Creek and it was
found that eleven (11) homes were discharging sanitary
sewage to the storm sewers. It can only be assumed that
this is by virtue of the fact that the house sanitary
connections are connected to the storm sewers with the house
storm connections having been made to the sanitary sewers.
Both the Region and the Town are therefore implicated in
correcting the situation.
REPORT:
It is totally unacceptable for raw sanitary sewerage to be
discharged into Soper Creek; therefore, the
cross-connections of sanitary house connections to the storm
sewers must be eliminated. This is a Regional
responsibility. Similarily, it is unreasonable to expect
the Region to continue to accept storm water being
discharged into its sanitary sewers and ultimately treat it
at the plant. Thus, the Town must become involved in
eliminating the storm connections to sanitary sewers.
- 3 -
As previously indicated, an extensive investigation of the
area in question was performed and it was found that about
eleven (11) homes were involved in the problem. Correction
of the cross-connections, if outside of the house, will cost
about $2,000.00 each. If the cross-connection is inside the
home, the Region proposes that the owner be responsible for
eliminating same. Assuming that all of the
cross-connections are outside of the home and that both the
storm and sanitary connections are involved, the total
corrective project will cost about $20,000.00 for which the
Town will be responsible for $10,000.00. If, however, it is
found that only the sanitary connection is involved, which
is not very likely, the Town should take the position that
it is not financially involved. Further, since this matter
is of mutual interest and benefit to the Region and Town,
the costs of the investigative work leading to the findings,
approximately $6,000.00, should be shared equally. The
problems relate to development and therefore any costs
incurred should be paid from the Lot Levy Reserve Account.

Commissioner of Works Dear Sir:
Please quote our ref: RE: Cross Connections - Beau Valley Estates Subdivision
SAN-N-1-1 Bowmanville
As discussed at our meeting on March 8, 1983, of the 266 homes
which were dye tested in the Beau Valley Estates Subdivision;
i .e. the area bounded by King Street east, Simpson Avenue and
Soper Creek, 11 homes were found to be discharging sanitary
sewage to the storm sewer. The attached list summarizes the
findings.
Please note that the houses at 42 Hobbs Drive, 1 Wilde Court, and
14 Hailey Court, have plumbing facilities in one washroom
connected to the storm drain inside the house. We suggest the
Plumbing Inspector deal with these as soon as possible.
Further investigation would have to be carried out on the
remaining 8 houses to determine if the cross connection is inside
the house or at the main sewers.
The Region is prepared to carry out the work involved in
correcting the cross connections at the main sewers. Because
there is a strong possibility that the storm laterals are
connected to the sanitary sewer where the sanitary laterals are
connected to the storm sewer, we feel that the Region and the
Town should each assume 50% of the cost of correcting the problem
on the street. In addition, both municipalities should each
assume 50% of the cost of the investigative work. We also
propose that the home owner be responsible for the cost of
eliminating an internal cross connection since, in all
likelihood, he connected .the plumbing for the washroom to the
storm drain himself.
