How
Does British Columbia Compare?
Percentage
of Canadian Population Served by Secondary or Tertiary Wastewater
Treatment - 1999


SOURCE:
Environment Canada. MUD database. 2001. NOTES: Secondary treatment
includes waste stabilization ponds. Insufficient data exist to adequately
assess the degree of treatment in NWT, Yukon or Nunavut. The data
for Canada do not include the Territories. Data refer to the proportion
of the municipal population served by a municipal wastewater system.
In Canada, nearly 75% of the population (22.5 million) are served
by municipal sewer systems. Population served by on-site sewer systems
are excluded.
How
does British Columbia compare?
- In
1999, the liquid waste of 63% of the population
served by sewer systems received secondary
or tertiary treatment. The 1999 Canadian
level was 78%, up from 56% in 1983.
- In
Alberta, Saskatchewan and Manitoba, more
than 99% of the population served by sewers
has secondary wastewater treatment or
better. In Ontario it is 94%.
- Of
the coastal provinces in Canada, British
Columbia has the highest proportion of
the population served by secondary or
tertiary wastewater treatment.
