I imagine that's going to connect to Proctor Creek, not go all the way to the Chattahoochee.

I'm a lot more skeptical of the quality of the river's water this far downstream than I am with it up by Buford Dam. Will this reservoir suffer E. coli outbreaks as they occur in the Hooh, I wonder?

The tunnel is five miles long, fwiw.

The water has yet to be treated at this point, the reservoir is raw water storage.

We can bore a 5 mile long tunnel, but we can't bring rail to the suburbs? Nice job, Atlanta.

I understand the water isn't treated. Is water in any big outdoor reservoir treated? Seems like a pretty bad place to keep water you intend to keep clean.

Why would you say an ex-granite quarry is a bad place for raw water storage. It will still have time to settle at the Hemphill Reservoirs before the Hemphill WTP.

Atlanta, the city, has nothing to do with rail being brought to the 'burbs. This park is within the city limits of Atlanta which also approved more funding for MARTA.

The water from the reservoir will undergo the same process as water acquired from other sources like lakes, rivers, and aquifiers. This reservoir is getting filled from the Chattahoochee.

New pumping stations will be built to draw water through a 10-foot wide tunnel, 200 feet beneath the ground. The tunnel will connect to the Hemphill Water Treatment Plant. A second tunnel will connect the plant to the quarry.

What I was saying is I expect water stored outdoors not to be treated. It's fine for raw water. Once you treat water, doesn't it need to stay relatively sanitary? You can't just store it outside, where it can get polluted, and then pump it to people's homes directly from there, so why bother treating it before you put it in a lake?

I don't know why you feel compelled to imagine alternate scenarios, since the tunnel is complete.

That's why they can draw from the reservoir to the Hemphill Treatment Plant when the need arises, and treat the water immediately prior to distribution.

Water towers and storage tanks, throughout the service area, which includes Sandy Springs and all of South Fulton Co (outside of East Point.)

Right.

My comments have already generated way too much discussion.

I was merely putting forth there's no need to specify the water in the reservoir is untreated because I doubt anybody would have assumed it would be filled with potable water.
