As a controls engineer, I program these type of systems all the time. A simple incorrect setting for when the pumps turn on and off (Lead,Lag) could cause this type of problem. It could literally be a new operator that fat fingered a parameter in the SCADA system. To hack these systems requires specific knowledge of exactly what kind of control architecture is in place at the facility and then having the appropriate software to gain access to the control system. Not that this type of hack cannot be done, but it does require specific knowledge. This really sounds like operator error to me.

I'm sorry that the word "FACT" hurt your feelings.
I'm actually amazed that you were able to spew that much hate and inference from one single word. It really is quite a feat. Congratulations!

As President Ronald Reagan said, "Facts are stubborn things"

I'd be just as comfortable with a Pebble Bed reactor...

But... micro nuclear reactors DO exist.

Ahh, I see the eco-nuts are in full force with this post... Putting on tin-foil hat...

Nuclear power - PLEASE put one of these in my back yard! http://www.nextenergynews.com/news1/next-energy-news-toshiba-micro-nuclear-12.17b.html

Mercury - Here are some mercury FACTS from the department of energy... http://www.fossil.energy.gov/programs/powersystems/pollutioncontrols/overview_mercurycontrols.html.

Drilling for oil - So while the rest of the world goes out and drills for oil, going so far as to cross drill under US soil, the United States should take a back seat and watch these resources be taken and used against us. Gee, I certainly hope the countries that are actually drilling for oil don't stop sending it to us. I'd hate to see what that would do to our economy.

Running multi-room audio can be challenging. Some things to consider... a typical amplifier will only work at 8 or 4 ohms per channel. This means you can only run 1 or 2 speakers on each channel before you run into trouble and put too much load on your amplifier. That being said, consider a 70v amplifier and speakers. A 70v system allows you to run multiple speakers from one amplifier and select the speaker wattage at the speaker. you still need to do the math to make sure you don't go over the amplifiers rating, but this is how restaurants and grocery stores do it. Since the feed signal is always at 70v, the speakers can be run in series. The speakers have a small transformer on them to select the wattage for each one. You can also get a volume control that does the same thing. One thing to note, Audio quality can suffer with a 70v system, but the trade off is long speaker runs in series and wattage selectable speakers. TOA makes a good 70v amplifier as does Peavey.
