Acting City Engineer

SUBJECT: Improvements to Mary Hill Road Sewerage Pump Station
(Public Works Committee Meeting May 29, 1990)

RECOMMENDATION:

That Council approve the expenditure of $31,800 to convert the electrical
service at this pumping station to three phase power and to provide new anodes
for corrosion protection, and that the funding be allocated from the 1990
Capital Sewer Budget.

BACKGROUND AND COMMENTS

The existing pumping station located in the 1300 block of Mary Hill Road is an
old station serviced by single phase power which is converted to three phase
power using 4n add a phase unit. With the construction of the
Westview/Genstar pump station further south on Mary Hill Road, three phase
power ducts will be installed past the existing station. Converting to three
phase will increase the reliability and reduce the maintenance costs at the
station.

When Westview reconstructed Mary Hill Road, they were required to install an
extension to the steel tan’. comprising the wet well of the station. When this

work was dore it was discovered that the anodes which protect the tank against
corrosion required replacement. Since these were not affected by tne raising
of the station it is appropriate that the City pay for the anode replacement.

The cost breakdown for the work is as follows:

Conversion of power to 3 phase $30 ,300
Replacement of Anodes ¢ 1,500

Total $31,800
