Looks like the intake would be higher elevation.
The Fraser River option said they accounted for sea level rise and salinity creeping up the river.

It's not about rainfall, it's about storing that winter rainfall for the summer peak demand when rainfall is lowest.

If there's less rainfall and snow, that increases demand and decreases the shadow storage that the snowpack provides. They can't provide more water than the watersheds accumulate regardless of storage anyways.

Coquitlam is interesting because it's a very deep lake, carved out by glaciation. There's abundance of storage there already. The current hydro and drinking water intakes are near the surface of the lake, the bottom of the lake is dead storage. It's like having trying to have a drink with a straw that's way too short.

If you've ever been to the Cleveland Dam in November, you'll know that we aren't exactly storing all the water the watershed currently collects

I wonder why the area north of Lynn Headwaters isn't under consideration.

officedweller · #**225** Posted **Jul 31, 2020, 9:52 PM**

Maybe Lynn Creek doesn't have enough flow.

The Lynn Creek watershed is a lot smaller than the main 3 watersheds, so it's not nearly as productive for water catchment. It never was designated an official watershed, and is instead designated as parkland, so you know it's never going to be considered.

i went there just in May of this year, it was also releasing water.

there is TONS of watershed capacity at the Cleveland Dam. but the dam is not high enough to store it. a raising program would be very expensive, but would create a lot of extra capacity.

The Cleveland Dam will probably never, ever be raised. At least as long as people live up the banks from it. Maybe it's my Vancouver drinking water privilege talking, but it always seemed crazy to me that people lived right next to Capilano Lake, I mean they could do anything to that water, I've seen The Tuxedo (2002)! Keep our water safe up in the mountains please!

Count yourself lucky there are plenty of places that fare a lot worse. Toronto gets its drinking water from Lake Ontario. And then there's Flint, Michigan.

Note they show the wrong flag.

Not sure where this fits so I will stick it in here. They have installed a large bank of Tesla Chargers on Lougheed Highway in Coquitlam, in the parking lot in front of Fatburger. I noticed they had been working on something there for a few weeks but didn't see the finished project until today.

There's some pictures here, apparently the fences just came down but the chargers haven't been activated yet: https://teslamotorsclub.com/tmc/thre...lam-bc.224233/

Years ago we installed a system in my building as we were starting to get too many pipe leaks. I'm betting they'll have to adjust it for this change.

Thanks for the post. Pardon the question, but would this affect our water's softness as well or is that completely separate?

I guess those systems add those minerals to the building system. This page says they bring it up to 8.0pH Metro Vancouver wants to get it to 8.5

It says they are adding calcium carbonate - so I figure that would make it harder.

I don't remember all the details of the system in my building (it was years ago... ) but the gist was that the water is too soft and taking minerals from the pipes. One thing that is being added is calcium.

madog222 · #**240** Posted **Apr 16, 2021, 7:22 AM**

Alkalinity and Hardness are directly linked but different, both are measured in milligrams of calcium carbonate per litre of water.
Alkalinity is a measure of the ability for the water to resist changes in pH, also known as buffering. Hardness is the total amount of calcium and magnesium in the water.

The issue of pipe wasting is from low pH caused in part by the low alkalinity of soft water.

Where the articles says calcium carbonate they are referring to the measurement, it’s not necessarily what is being added to the water.
