THE CORPORATION OF THE CITY OF PORT COQUITLAM

MEMORANDUM

Mayor and Aldermen January 2, 1981

F..E. Peters, P. Eng.,
City Engineer

Association of Concerned Citizens Delegation

There is an item on the agenda dealing with a delegation
from the Association of Concerned Citizens. For the information
of the aldermen, I have put down any information that is available
on the ten questions listed in the letter.

1. We have no current plans for the disposal of the old
pumps. Naturally, we intend to leave them in place and operational
as long as B.C. Hydro allows us to have a hookup.

2. The capacity of the existing pump was estimated to be
about 67 cubic feet per second when new. There is no telling
what the present capacity is as the pump is old and worn out.

The two new pumps being installed at Dominion under the current
project have a capacity of 75 cubic feet per second. As the two
new pumps are smaller than the existing pump, they can start
pumping sooner without running into cavitation problems and there-
fore should provide a better service.

3. Same answer as Number 2.

4, We spent about $65,000 on ditch cleaning in the
agricultural area in 19890 and about $220,000 is projected as the
total cost of the pump station.

5. This is partly answered in My report on the Boxing Day
flooding. Very simply, we have had two major storms in a period
of about one year coupled with the fact that this year the water
from the north part of the agricultural area was able to get to
the Dominion Avenue area faster.

6. It is very difficult to estimate the power consumption
costs as the B.C. Hydro rates depend not only on the energy
consumption but also on a monthly demand charge. The costs depend
on the running time as well as on the distribution of the running
time throughout the year. However, it is expected that the power
costs for the old and new pumping station will be similar but that
the maintenance cost for the new station will be lower.
