BCWWA – Water Conservation

This presentation focuses on Programs and Technology and the current trends in water conservation.

Watersense is like the EnergyStar label but for water. This could be harmonized with Canadian standards.
Alliance for Water Conservation
Uniform Plumbing Code (UPC)

BC building code 2008 – 6 lpf will be legislated this year.
Newer standard is the High Efficiency Toilet (HET) – 4.9 lpf maximum.
Urinals – why is the BCBC so much higher than the best available?
Waterless urinals will be allowed in UPC 2009.

Hot Water Fixtures
Multiple shower heads are NOT regulated. UPC will likely allow based on shower floor area.
Rain Curtain is not regulated.

Water and Energy
How much funding is BC providing for R&D for water efficiency? California funded $10M last year.
Conventional systems can’t adequately provide hot water to faucets in lengthy systems – there are no recirculating elements. Manifold systems are not any better.

Energy Independence and Security Act (2007) will now (2010) regulate the amount of water that a washing machine or other appliance uses.

Market Transformation
Who do people trust. Not the government! They trust Friends, landscape professionals, internet, books.
What are the intrinsic values that people hold?
Need to address people’s intrinsic biases – what does water efficiency look like to people?
Engage the trusted advisors – Canadian Tire, Rona, Home Depot etc. Landscape Professionals. Plumbers.

New Initiatives
Greening of the BC building Code

  • Part 10 – Energy and Water Efficiency
