FLASHBACK TO 2010: “Home Depot in the City of Courtenay established a BC precedent when it implemented a deep deep-well system for injecting rainwater runoff and recharging the underlying groundwater aquifer,” stated the City’s Kevin Lagan when he shared the story with a provincial audience at the ‘From Rain to Resource Workshop’ hosted by the Okanagan Basin Water Board
Note to Readers:
In October 2010, the Okanagan Basin Water Board (OBWB) and the BC Water and Waste Association co-hosted a 2-day workshop titled ‘From Rain to Resource: Stormwater Management in a Changing Climate‘. Day 1 was geared toward technical operational and planning staff . The focus was on site-level best practices and tools to deal with various situations. One of the case studies was the Home Depot development in the City of Courtenay.
Kevin Lagan tells the story of the first deep-well application of rainwater runoff to be implemented in British Columbia
“In 2003, the Home Depot development application in the City of Courtenay was to build a store and parking lot covering 90% of a four hectare second growth coniferous forest property,” reports Kevin Lagan, Director of Operational Services. He will tell the Home Depot story at the Okanagan From Rain to Resource Workshop.
Capture Rain Where It Falls
“The City required that post-development rainwater and stormwater flows leaving the site were equal to or less than the pre-development flows. For this property that was effectively zero.”
“How did the developer meet this requirement of replacing a forest with impervious areas and has the solution been successful? Learn about the challenges encountered and the innovative solution used.”
“Home Depot established a BC precedent when it implemented a deep deep-well system for injecting rainwater runoff and recharging the underlying groundwater aquifer.”

Read Innovation in the Comox Valley: First Wal-Mart, Then Home Depot, posted on waterbucket.ca in October 2007 — The Wal-Mart development in the City of Courtenay precipitated the beginning of a major change in how the City administers the zoning/development/approval process, collaborates with other agencies and also manages the rainwater resource.
An Early Application of the Water Balance Model
“The Home Depot project was one of the earliest applications of the Water Balance Model when we created this web-based tool in 2003. Significantly, Home Depot is situated on high ground that drains onto prime agriculture land. Because the City of Courtenay was a charter member of the Inter-Governmental Partnership, the Agricultural Land Commission linked its approval to use of the Water Balance Model,” recalls Ted van der Gulik, Chair.
“Subsequently, the City co-hosted one of our first Water Balance Model training workshops at North Island College in May 2004. The target audience was the streamkeeper commmunity. Our purpose was to demonstrate how this decision support tool can be used by a range of stakeholders.”
