LEVELS OF
ENGAGEMENT
LGWWTP - Project
Charter
To develop a project definition report for the Lions Gate WWTP by implementing an integrative process that guides and inspires higher performance and continually improves engagement around issues of sustainability in the community and nearby watersheds,
In a way that engages project participants to experience our role in the water cycle and deepen our understanding of how the business of wastewater management can positively affect it,
So that the project manifests the practicable application of Metro Vancouver’s Vision for a Sustainable Region and sets a new standard for Wastewater Treatment Plants as a community asset.
Project Principles
Think Big: think beyond traditional boundaries . . . in order to:
•
•
•
•
integrate technical and living systems
understand effects beyond site boundaries
develop longer term sustainable solutions
serve larger ecosystems
Embrace Waste: use waste as a valuable resource . . . in order to:
•
•
•
•
•
displace fossil fuels and reduce GHG
generate local renewable energy
offset potable use
recover nutrients
rehabilitate degraded ecosystems
Optimize Interrelationships: seek creative solutions that transcend constraints . . . in order to:
•
•
reconcile cost, value, and performance
maximize exchanges
Enrich the Community: increase quality of life & economic development . . . in order to:
•
•
•
transform the health of the place
become a catalyst for regional change
be an affordable asset for current and future generations
Inspire Stewardship: foster responsibility, transparency, awareness, & education . . . in order to:
•
•
expand active engagement in the health of the community and ecosystem
understand behavioral impacts

Concept 1:
INTERTIDAL WETLAND
A Constant Exchange of Nutrients
This concept is focused on NATURE
Like an intertidal wetland, this concept will celebrate and extend the complex
overlaps between the wastewater treatment process, tidal phases, downstream
impacts, hydrological cycles, and nutrient exchange opportunities in a way that
develops a resilient, durable integrated system, expands the life giving force of
water, and maximizes the human perception of water in all its forms, so that…

Concept 1 – An Intertidal Wetland
Concept 5:
FLEA MARKET
A Constant Exchange of Knowledge
This concept is focused on COMMUNITY
Like a flea market, this concept is focused on the exchange of knowledge and
improving social health; it’s primary purpose is to create value in a manner that
derives maximum social, economic and technical benefit by leveraging on the
unbridled potential of human ingenuity, so that...

Concept 9:
DRAGON’S DEN
Long-Term Net Revenue Generation
This concept is focused on MONEY
Like the popular television show The Dragon's Den, this concept is characterized
entirely by maximizing net revenue from the plant in a manner that is highly
effective, economically intensive and unsentimental, so that...
