Re: Water Supply to 934 Victoria Drive

Council. had requested a further report on the water suppiy to
Art Ricard's proposed subdivision at 934 Victoria Drive. The attached
sketch shows the existing watermains available in the area of Victoria
Drive. A larger map will be available on the wall of the Council Chamber
to assist in the discussion if further detail is required.

¥low tests were done by the Fire Department at hydrants 1 and
2. The standard method of measuring flows is to measure the difference in
pressure between the static or no-flow condition and the pressure with a
flow through a known orifice. In the case of both of these hydrants along
the 4-inch watermain on Victoria Drive the pressure when the hydrant was
opened was so small as to be unmeasurable. This would indicate a flow far
below the 125 g§alions per minute which was calculated on a theoretical basis.
It has since been determined that one of the reasons for this low flow is
that no connection exists between the 4-inch main on Victoria Drive and the
10-inch main on Lyawoed or the 12-inch main on the ‘diagonal portion of
Victoria Drive. Other possible reasons include the possibility of a main
which is very badly barnacled on’ the inside or the possibility that a portion
of the main may have been partially frozen,

At the time of construction of the Ricard's subdivision along
Victoria Drive and Victoria Place, it was intended that the 12-inch main
be connected across to the 4-inch main. For some reason this was never
done. Art Ricard has agreed to puy for this connection at this time in
order to allow us to do a realistic test of what water flows will be avail-
able at his new subdivision and has deposited a cheque for $2,000.00 to
allow us to make this connection. We Will be proceeding with this connection
within a week and hope to be able to provide further flow information shortly,
