Domestic Water Use
Transcript of Domestic Water Use
sinks, showers, sprinklers, toilets, laundry, etc.
thermal power generation
main water uses in canada.
60% - thermal power generation
18.5% - manufacturing
9.6% - municipal
8% - agriculture
4% - mining bc and canada.
.5% of world population
7% of world's renewable water supply
multiple dams/reservoirs in bc, northern glaciers, great lakes reservoirs.
Coquitlam - Buntzen
Ash River - Elsie Dam
Puntledge River - supplies Courtenay
Shuswap Falls and Sugar Lake
Peace River british columbia.
we use more water per capita than anywhere in not only in candada, but north america
490 litres a day per person - bc
canada's average - 329
u.s. average - 380
canada - reluctancy to trade to prevent environmental decay
water levels drop - canada has a chance to profit
to compensate profit and environment, small scale trade to u.s.
plans for large scale transport from great lakes being made water classified as a commodity since the 80s
international boundary waters treaty act
great lakes 15% of canada's water supply
promotion of cooperation rather than war elsie dam.
water from the ash river on vancouver island
77 million cubic meters capacity
three dams on this river just in b.c.
continues into the u.s. where more dams reside
mica dam, revelstoke dam, keenleyside dam
15 cubic kilometers capacity
northernmost dam on the columbia river
leads directly into the revelstoke dam revelstoke dam.
strictly hydro electric keenleyside dam.
8.63 cubic kilometers capacity
also a hydroelectric dam
built as a part of the Columbia River Treaty
arrow lakes peace river.
w.a.c. bennett dam
willston lake reservoir
74,000,000,000,000 litres of water global water.
some areas less than 1/6 people can access safe drinking water
developing countries use about 50-100 litres a day
insufficient regions - 10-40 a day
3900 children die each year due to water-borne diseases
global water stress.
water usage compared to resources
high stress areas - central u.s., most of europe, northern africa depletion.
climate contributes to droughts or flooding
thermal generation, agriculture, mining, etc.
more evaporation due to global warming due to all of this, water needs to be preserved. and even though, as british columbians, we have the luxury of having clean water from our sinks, measures are still being taken to preserve all we have left. the truth is, most rivers in b.c. flow north, and with the rapidly changing climate, that luxury could soon be gone. b.c.'s "Living Water Smart Plan"
includes 40 ideas
goal to increase water efficiency by 33% by 2020
mandatory low flush toilets/shower heads, using front loading washing machines rather than top loading, fixing leaks/dripping taps, etc.
2012 - large water users must report usages
protection of rivers, lakes, and watersheds
more efficient irrigation methods
in schools, students must get to know a nearby stream and assess its health as to keep youth from being disconnected with nature. "We have to stop taking water for granted. I don't have a magic wand to create more." - Environment Minister Barry Penner THE CLEVELEND DAM. built in 1954, 40% of the lower mainland's fresh drinking water comes from here.
located in the greater vancouver water district in north vancouver.
blocks the capilano river, acts as a reservoir with a pump station, and a hydroelectric dam.
