RESOLUTION AUTHORIZING SANITARY SEWER CONNECTION TO
THE NEW BRIGHTON SANITARY SEWER SYSTEM
WHEREAS, the trunk sanitary sewer system of the City of
Arden Hills (the "City") between Interstate Highway No. 694 and
the south corporate limits of the City (i.e., District W) has
been determined in the Arden Hills Comprehensive Sewer Policy
Plan ("CSPP") to be inadequate, and
WHEREAS, such inadequacy.in that portion of the City's
trunk sanitary sewer system which runs through District W is
because of sewage flows from District NC as indicated in the
CSPP, and
WHEREAS, sewage flows from District NC are pumped three
(3) times in the City before reaching the Metropolitan inter-
ceptor in Roseville, and
WHEREAS, the developable area of District NC is approxi-
mately 1,100 acres, the ultimate average daily flow through
District NC is estimated to be 0.793 M.G.D. (i.e., 793,000
gallons per day), and the estimated peak flow is 4.1 cubic feet
per second, (��ed on a 3.3 peak flow factor), and
WHEREAS, the projected flows from District NC are as
follows:
Year
1980
1985
1990
Population
Equivalent Average Flow M.G.D.
2844 0.284
5033 0.503
5749 0.575
Peak Flow C.F.S.
1.58
2.80
3.20, and
WHEREAS, it is anticipated that trunk sanitary sewer
capacities in District W will have to be increased by 1984 if
District NC continues to flow into District W, and
WHEREAS, a gravity sanitary sewer diverting sewage flows
from District NC to New Brighton would eliminate the need for
.�� Sewer Pumping Station No. 10 in the City and the need for further
' pumping of sewage from District W, resulting in a saving of
electrical energy and other operation and maintenance costs, and
� �,
WHEREAS, in the City's report entitled "Proposed New
Brighton Sanitary Sewer Connection", dated August 18, 1981, a
copy of which is attached hereto, it was shown that Plan B--the
plan therein which propased the construction of a gravity sewer
to New Brighton--provided a long-term savings to the City of
approximately $325,000.00, and
WHEREAS, the City's Council approved Plan B at its meeting
on August 3T, 1981, and
WHEREAS, the City's Sewage Pumping Station No. 2 in
District W will have to be rebuilt by 1983 if the prajected flows
from District NC shown above occur, and
WHEREAS, the Metropolitan Waste Control Commission (the
'°MWCC") has stated that it supports the joint use of inplace
sanitary sewer facilities and has determined a proposed diversion
of sanitary sewers from the City's District NC through New
Brighton will not overload the present Metropolitan interceptor
or have an adverse imgact on the Metropolitan Wastewater Treat-
ment plant, and
WHEREAS, the City believes the existing 42 inch trunk
sewer in New Brighton and the extension thereof to the City's
corporate limits meets the criteria set forth by the Metropolitan
Council and may qualify as a Metropolitan interceptor sewer, and
WHEREAS, the City has been advised by representatives of
New Brighton that excess capacity amounting to four (4) cubic
feet per second is available in New Brighton's 42 inch trunk
sanitary sewer, and
WHEREAS, the City of New Brighton has indicated it would
make the aforesaid excess capacity available to the City,
NOW, THEREFORE, IT I5 HEREBY RESOLVED by the City Council
of the City of Arden Hills that the City hereby respectfully
requests of the Metropolitan Council:
1. That the Metropolitan Council accept a certi-
fied copy of this Resolution and refer the same
to the MWCC for its review and recommendation
back to the Metropolitan Council;
2. Upon favorable recommendations from the MWCC to
the Metropolitan Council, the Metropolitan
Council:
(a) Approve as soon as possible the City`s
Plan B for diverting sewage from the
City's District NC into New Brighton so
that the City can proceed with its
contemplated improvements of Sewage
Pumping Station No. 2; and
(b) Authorize the MWCC to acquire New
Brighton's 42 inch interceptor sewer and
to extend the interceptor to the City's
westerly corporate limits by 1984; and
3. The Metropolitan Council approve the City's
proposal of a New Brighton connection and
' consider this approval as a modification of the
City's CSPP.
