Chilliwack Lake is too far. Chechalis Lake is probably too small to be worth it without damming. How much would damming expand its capacity?
Harrisson Lake also has some quality issues from the Hot Springs area. Stave Lake experiences significant agricultural runoff from Miracle Valley.
I mean, I guess you could use the Harrison or Stave for agricultural irrigation only, since quality is less essential there...  |
Fraser River s Ideal source of fresh water. For we already take water from it indirectly from langley going east. As Langley gets a portion of their water from wells. The Aquifer that they use is fed through layers of sandstone and other formations to create a constant supply of fresh water that will never run out. The Fraser is, in general, a fairly clean river except for the silt.
Metro Van does not really talk much about there water supply system much. We just spent close to 2 billion on new water supply tunnel to Surrey, and then there was the new capalano/seymour watershed improvement project 15 years ago that created 1 large system. Taking water from mountain lakes was a cheap way of getting water in the old days now we have an ever growing population with greater demands on water. Going forward more of our water will need to come from easier sources. There was a proposal from an engineering company a few years ago to build a water filtration plant on the Fraser. Metro went with new filtration plant at Seymour.
Desal plants are too costly to build and run, so the new trend is a waste to tap systems as cost per litre are cheaper. The tech comes out of Isreal. Southern California has several online now or plan to come online.
Potable water is also being used more for agriculture as greenhouses take water from the city system, not canals here. SO as delta continues to change from field crops to greenhouse crops a large demand comes about. Add in the immigration issues a better source of water in the next 100 years will need to be found
