Buying near wastewater treatment facility

Hello,

I'm thinking of purchasing a new home near Phoenix, AZ (first time
homebuyer) and about 1/2 mile to the north they're building a small
wastewater treatment facility. I'm not knowledgable in the area of
wastewater treatment, so forgive these questions if they seem a little
basic:

1) Is there any difference between "wastewater treatment" and "sewage
treatment"? Sales agent says there is but she doesn't know what that
difference is. Will raw sewage be pumped into this station?
2) Should I be concerned about smell from 1/2 mile away? My house will
typically be parallel to the plant and not upwind or downwind during the
prevailing wind. Does the technology they use now (this is supposed to be a
"state-of-the-art" facility) reduce the chance of odor?
3) Is this going to affect my resale value?
4) Should I even be concerned that this plant is going in so close to my
home? Agent says these things are in most new tracts now, but I always take
what the agent says with a large grain of salt.
5) Is it possible drinking water will come from this plant? My inclination
would be no, since current homes exist and have water service already (this
plant is under construction). I've heard about using reclaimed sewage as
drinking water. Supposedly pretty clean, but what a mental hurdle.. ;-)

Thanks!

Scott
