MEMORANDUM

MEMO TO: Igor Zahynacz November 2%
City Engineer

MEMO FROM: Gordon Voncina
Operations Manager

SUBJECT: Hyde Park Sanitary Pump Station

Please be advised that we have experienced ever increasing problems with
our sanitary pump station at Hyde Park.

The sanitary pump station has an Add~a-phase convertor which has been
malfunctioning. Graham Stewart, our electrician has repaired the unit several
times, however, recommends the add-a~phase be removed and replaced with a 600
V service.

The present two pump system is powered by 230 volt - 3 phase power. In
the past, we have found these pump stations unreliable due to the insufficient
power available to grind anything but the smaller pieces of waste flowing into
the station. During heavy rains considerable infiltration of water oceurrs in
the system which adds to the pumping problem, causing the pumps to run
continuously. Pump no. 2 is presently shut down and unavailable should
pumping be required.

It is recommended that the City replace the Add-a-phase and upgrade the
electrical system within the pump station expeditiously to correct the present
problems and eliminate the excessive level of maintenance required to keep the
pump station operating.

A breakdown of estimated costs are provided for your review:

B.C. Hydro to install 600 V $ 7,000
Removal of Add-a-phase $ 2,500
Upgrade electrical service & lines c/w transformer $ 4,000
Flygt to upgrade both pumps $ 2,000

TOTAL ESTIMATE $15,500

Would you kindly advise the Public Works Committee of the problen,
requesting a source of funding for the remedial work.
