therefore have to be turned on manually. This problem normally
would only occur if there was a fire on Mary Hill with a majer
demand for water fram the pumper truck. The requirement to
turn the pump or Pumps on manually could resu!t in some delay
in getting adequate water pressure to the fire site if the fire
is at the top cf Mary Hill.

The long range plan for provision of adequate fire flow to
Mary Hill is through the pumping station being built by Genstar
as part of their development requirements. This pumping
station will feed back through a water main which wil |
eventually loop into the old part of Mary Hill at Western
Drive. The looping back in dependent on construction of future
phases of the Genstar subdivision, and therefore, the exact
date cannot be anticipated.

The recommendation fer the Heated Pressure Sensing Station
is an interim measure until we can provide flow from the
Genstar site. The Heated Pressure Sensing Station would allow
the Penny Place Pumps to be left on automatic operation al!
winter. In most cases the winter water demand would still be
fed from the Trenton main. However, in the event of a major
fire, the Penny Place Pumps would automatically come on to
boost the pressure.

The second recommandation for a Spare pump is as a safety
factor. The existing two pumps are both ofd and worn and
cannot be relied on to provide consistent full-time service.

Our intention is to have a Spare pump which would be used to
replace either of the existing pumps in the event that one of
the pumps fails. If a failure occurs during the summer ‘months,
we could well be faced with a lengthy delay in ordering and

purchasing & new pump.
