Okanagan Lake Project
Okanagan Lake Project - Updated September 2014
The Okanagan Lake pump station began pumping Okanagan Lake water into McKinley Reservoir in early 2014. The creek water source, previously the main water supply for McKinley Reservoir, is no longer providing any water to the reservoir. Some residual creek water remains in the reservoir but is slowly being displaced by the Okanagan Lake source.
Since late spring, the District has received calls from residents throughout the distribution area, commenting on the clarity of the water. Feedback and comments like these are welcomed by Staff and Trustees alike.
Some previous notes about this project are below.
October 7, 2013
On October 2, 2013, GEID held the official ceremony, attended by over 75 invited guests and dignitaries, to celebrate construction of the newest pumpstation on Okanagan Lake. The station is named after Joe Bulach, one of the longest serving Trustees of the District. The attached photo, file, courtesy of KelownaNow.com, shows the newly unveiled pumpstation plaque with Ron Cannan, MP, Joe Bulach, GEID Trustee, and Norm Letnick, MLA. An additional plaque for the station is now hanging in the District offices at 445 Glenmore Rd. Pump station Plaque.jpg

Display boards were placed throughout the station for guests to view during the ceremony. Information from those boards is attached & includes: OK Lake Display Panels.pdf

Water pumped from Okanagan Lake through the Joe Bulach pumpstation flows through new watermains on Shayler Rd and overland to GEID's largest Reservoir on McKinley Road. From there, the water flows into the distribution system for Glenmore, including areas such as UBCO, the Kelowna Airport, Quail Ridge, Wilden and the Glenmore Valley to Sexsmith Rd.. Customers within the Ellison area (east of the Airport) are not supplied with water from .
The District lowered water levels in McKinley Reservoir prior to Okanagan Lake water flowing into reservoir. This drawdown will help reduce the amount of time required to replace creek water in the reservoir., As a result of the drawdown, GEID also switched to the lower intake. Until creek water in the reservoir is completely replaced by Okanagan Lake water (which can take several months through to mid-2014), water drawn from the lower intake may have higher colour and turbidity than is currently being supplied to Glenmore customers.
While the water levels are low enough, GEID also plans on filling some areas ("fingers") of the reservoir which are relatively shallow and can, due to higher water temperatures, be home for millfoil, ducks and other wildlife. Once this work is complete, GEID will be able to raise the reservoir levels with Okanagan Lake water. Fluctuations in colour and turbidity may continue over the next few months as the District adjusts and fills the reservoir.
As noted above, creek water is currently the primary water source in McKinley Reservoir. By mid-2014, the primary water source in the reservoir will be Okanagan Lake water.
Some previous notes about this project are below.
Pumpstation - April 25, 2013
The District's contractors are on schedule with the Okanagan Lake Project. The design of the new pumpstation was completed in June 2012 and tenders for construction were issued June 29th. Several bids were received and the winning bidder, Maple Reinders, was awarded the contract in early August. Construction on the pumpstation was in full swing as of early September, 2012. During the fall 2012, site preparation and pipe works were completed and during the winter, work continued on the concrete works. As of April 25th, the roof has now been completed.
Intake - September 30, 2011
The Intake Works were deemed substantially complete on September 29, 2011, and the contractors have met the DFO deadline.
As part of the approvals process from the Department of Fisheries & Oceans, and in consideration of fish spawning, work in Okanagan Lake could not continue beyond September 30th, 2011
The intake is 35 metres deep and accesses the highest quality, lowest risk raw water in the region. This intake will be one of the four long term primary domestic water sources for Kelowna. As the intake was installed in a black-listed Kokanee Salmon spawning area requiring the highest protection, extra precautions such as dual silt curtains and total reconstruction of the disturbed lake bed were part of the work.
May 2011 Announcement
In May, 2011, Glenmore-Ellison Improvement District announced that it has obtained the final approvals from Fisheries and Oceans Canada. Planning began for GEID's Okanagan Lake pump station before 2005, with land acquisition completed in 2009. A contractor was selected in 2010, but since environmental approvals took from December 2009 to May 2011 to complete, construction was delayed from 2010 to 2011. Over the past three years, GEID has completed other portions of the project, including approximately 2 km of large diameter water transmission main (750m or 30 inch) between the pump station site and McKinley Reservoir.
Construction of the pump station began June 2011, with completion expected in late 2012. With the supply of Okanagan Lake water to GEID's McKinley Reservoir, customers in the Glenmore Valley should expect to see less colour and turbidity in their drinking water. Most importantly, by 2013, this should allow GEID to remove the longstanding Water Quality Advisory that has been in place in Glenmore since 2006. "GEID's customers have been waiting patiently for higher quality water, and GEID's Board of Trustees is pleased to announce that the wait is nearly over", said Bob Fugger, Chair of the Board of Trustees.
Once higher quality Okanagan Lake water is available to GEID, ultraviolet (UV) disinfection is planned for the near future as the next step in improving water quality. Subject to meeting Interior Health's filtration deferral criteria, UV disinfection is expected to allow GEID to fully comply with Interior Health's 4-3-2-1-0 drinking water guidelines.
"GEID's intake will be one of the deepest in Okanagan Lake, and is in one of the best locations, distant from local valley creeks and urbanized areas. By utilizing water from deep within Okanagan Lake, along with state-of-the-art UV disinfection, GEID will be able to provide safe, cost effective, high quality drinking water that meets Canadian Guidelines year-round", said Bob Hrasko of Agua Consulting, GEID's engineering consultant.
