New Water Use Reduction Regulations in the City of Vancouver
On April 12, 2017, City of Vancouver council voted to approve changes to amendments to the Water Works by-law and the 2014 Vancouver Building By-law.
As a property owner, developer, contractor or designer how do these changes affect you?
1. Ban of Once Through Cooling (OTC) Systems. Once Through Cooling systems use domestic cold water to provide cooling to air conditioners, coolers, refrigerators, and ice machines. The water is dumped to the drain once the heat has been rejected into it.
While OTC is no longer common for regular uses, they were still used until recently regularly for backup emergency cooling. In addition, there are many older OTC systems in older buildings still actively used.
The new regulations prohibit all OTC systems for all new construction immediately. For existing systems, the ban comes into effect on January 1, 2020.
There are many non-water consuming alternatives to an OTC system such as air-cooled heat pumps.In most cases, the pay-back to installing an alternative system would be less than 7 years.
2. Lower Flow Plumbing Fixtures. New lower flow plumbing fixtures will be required for all new construction:
- Water closet: 4.8 litres per flush (Lpf), with discretion of the Chief Building Official for up to 6.0 Lpf in retrofits
- Shower head: 7.6 litres per minute (L/min)
- Lavatory faucet: 1.9 L/min, except 5.7 L/min for private use areas
- Pre-rinse spray valve: 4.8 L/min
- Wash fountain: 6.8 L/min for each plumbing fixture
These plumbing fixtures match flow rates that are recommended in the 2015 National Plumbing Code. Lower flow fixtures have been used in LEED buildings for more than a decade and are widely available from wholesalers.
This amendment will come into effect on January 1, 2018.

The Globe and Mail recently acknowledged Burnaby as the site of a booming trade in the industrial real estate where films and TV series are produced.
The B.C. Film Industry and Industrial Real Estate study, prepared by the Colliers International Group and released Tuesday, found that 48 per cent of the 2.1 million square feet of Metro Vancouver studio space – a mix of purpose-built studios and former industrial spaces – is actually in Burnaby, to the east of Vancouver.

Our Service and construction team had the pleasure of working with Bridge Studios in Burnaby to complete their Sound Stage 7 facility in 2012.
In line with the film industry's expansion, BC Comfort is currently working on the development of additional Sound Stages with Bridge Studios which will start construction this summer.
