FS#2 Fact
Sheet on the Municipal Sewage Regulation
Highlights Regarding
Use of Reclaimed Water
Introduction
British Columbia
recently enacted the Municipal Sewage Regulation that replaces
a time-consuming permit system and spells out new rules for treating
sewage, generating and using reclaimed water, and disposing of
effluent that cannot economically or practically be reused.
This fact
sheet describes the production and use of reclaimed water.
What is
reclaimed water?
Sewage treatment
plants produce effluents that historically were treated and released
into the environment without considering the environmental and
other benefits of reuse. New technologies and processes have been
developed to treat the sewage so effectively that the treated
water can be reused for a variety of different applications.
Why is
it important to use reclaimed water?
By using
reclaimed water for non-potable uses such as irrigation, stream
augmentation or toilet and urinal flushing, potable water can
be conserved for end-uses such as showering, cooking and drinking.
Hence, a water reclamation facility conserves water, enables beneficial
use of reclaimed water and reduces the amount of effluent going
into the environment. There is a net benefit for the environment.
Water reclamation
integrates both water supply and wastewater treatment systems
and by doing so conserves water, protects the environment and
may save money.
How can
reclaimed water be used?
The Municipal
Sewage Regulation provides strict rules for all possible uses
of highly-treated wastewater. The list includes outdoor uses such
as agricultural and park irrigation and fire-fighting, and inside
uses such as flushing toilets and urinals, primarily in commercial
or office buildings.
In order
to reuse the water, certain infrastructure must be in place. For
indoor uses, separate plumbing is required. For outdoors, a second
water main and associated valves and pumps will be needed to move
the reclaimed water to where it is needed. Measures to prevent
cross-connection are required in either case.
Are there
any examples of the use of reclaimed water in BC?
Yes, a BC
company has designed and installed a water reclamation plant in
an office building near Sooke. Water consumption and effluent
outflow have been reduced by more than 90 per cent compared to
a similar office with conventional water and sewage systems. Effluent
quality is high, protecting the high water table in the area.
A second
example is the City of Vernon, which for over 20 years has been
irrigating rangeland, sports playing fields, golf courses, and
tree nurseries with treated wastewater from the local sewage treatment
plant. In Vernon's case, the use of reclaimed water has virtually
eliminated the discharge of effluent to the environment.
The community
of Cranbrook has also been irrigating rangeland for several years.
As well,
there are several golf courses located throughout BC that use
reclaimed water for irrigation and the first public school in
Canada using reclaimed water for flushing toilets and urinals
is located in BC
In general,
the use of reclaimed water conserves freshwater supplies, reduces
the discharge of sewage to the environment and may save money.
What benefits
are there if we use reclaimed water in BC?
The potential
for water reclamation in BC is excellent in areas where water
is in short supply or there are environmental concerns about the
discharge. In addition there can be significant cost savings for
local governments, which make water reclamation a viable option
to consider. For example, the City of Vernon anticipates saving
50 per cent of the capital cost of its water and wastewater needs
over the next 20 years through its use of reclaimed water initiatives.
Several other communities in BC (Oliver, Osoyoos, and Armstrong)
have also determined that use of reclaimed water makes sense from
both economic and environmental perspectives.
For new developments,
if water reclamation is integrated into the design from the beginning,
the short-term increased costs of infrastructure could be offset
by long-term savings in water costs, discharge costs and environmental
protection.
