Historic Sites of Manitoba: St. Boniface Surge Tank and Pumping Station (866 Tache Avenue, Winnipeg)

A cylindrical structure at the foot of Tache Avenue in St. Boniface, built between 1918 and 1919 by Thomas Kelly and Sons, provided a means whereby the pressure from 24 kilometres of water flowing at a significant velocity through the Shoal Lake Aqueduct is relieved automatically when the rate of discharge of the downstream system is reduced. Without the tank, the conduit would burst.

An adjacent booster station was designed by the architectural firm of Green, Blankstein, Russell & Associates and built in 1951 for the Greater Winnipeg Water District (GWWD). The facility was opened formally on 31 May 1951 by GWWD Administrative Board Chairman Garnet Coulter. A commemorative plaque also named GWWD officials William D. Hurst (Chairman of Commissioners) and Nathan S. “Nat” Bubbis (General Manager).
