KEM wins contract to design and manufacture Greenwood Head Tank for the Seymour-Capilano Filtration Project
January 18, 2008
Vancouver, BC; The GVRD had seen previous tanks that were manufactured by KEM for another phase of this project. GVRD invited us to bid on the contract to design and manufacture the Greenwood Head Tank for the Seymour-Capilano Filtration System project.
This tank was built for the storage of water and to maintain the head pressure. It was manufactured using the design codes: AWWA D100, ASME, BC Building Code. Construction: Carbon steel with a heavy duty AWWA c222/NSF51 approved paint system applied. In order to reduce costs and due to rain coast winter weather issues this tank was fully shop assembled, including the coating requirements.
This 10’ diameter x 75’ high tank represents KEM’s tallest manufactured projects. The Greenwood Head Tank was built using the strict codes set down by the GVRD. The circumferential welds were so crucial to GVRD’s QC requirements that this tank became the most extensively x-rayed project that KEM has ever manufactured. Much of the tank was 100% x-rayed and with less than 1% of the welds needing repairs both our client and KEM were pleased with the results.
“The Greenwood Head Tank project was Knelson’s first foray into the American Water Works Association (AWWA) for tank building.” commented Neil Fawcett, KEM Department Manager.

After successful completion of the tank and shipment to the site, January 18, 2008 marked the day that the Greenwood Head Tank was erected at the Seymour-Capilano Filtration plant. “It was a sight to see” said Jari MacHolm who is the Manager of Engineering/Projects. “The many onlookers were impressed with the smooth process as the tank was being erected.” said MacHolm. “When the tank slipped smoothly into place and every one of the 32 by 2 ½” diameter bolts lined up perfectly to our bolting flange we had passed the last of our hurtles in this project.” comments Neil. It was part of KEM’s contract to design and supply the anchor bolts as well as developing a procedure to ensure that this connection went smoothly.
KEM’s extensive capabilities including electrical and mechanical design support, fabrication of various types of metals, rubber lining, painting and CSA certified panel building enabled the GVRD to work with just one service provider for the entire project all in the same location.
