Why bother with trying to find a viaduct, that may or may not exist, when
electrical substations, are all over the place and the only thing guarding
them is perhaps a 6 ft chainlink fence only a few feet away from the
A few feet to a couple of yards of chain or metal cable at 3 am could
paralyze an entire city and cause economic and social chaos ...... For less
than $10 worth of equipment, one could cause; no street lights, stop lights,
even burglar alarms, no power for pumps to move the water, and the like.
If several are hit at the same time around the town / city, it could knock
out the grid for the entire city, and maybe beyond....think about the last
New York power outage......not a pretty picture.
A very small container of Anaerobic bacteria could if added to a water
supply not at the lake but at the pumping or testing station could do
things, as could thyphus etc .
IMO, Ian's scenario is the most likely to succeed of the ones mentioned.
At the resevoir end, the volume of water as well as any testing done in
treatment would make that the least likely. At the pump/treatment plant,
security would be a big factor in whether or not that's the viable option.
After it leaves the plant and is somewhere in the distribution system is
where a saboteur would have privacy, time, and best chance of the agent
being unnoticed, until too late.
I have to say I think it's probably most easy and effective to blow the main
viaducts with explosives. Look what's been done with human and vehicle
bombs, not to mention RPG's. A fairly well-planned operation could bring a
city/cities down quick. Think how tough it was to get water to significant
numbers of people in the wake of the hurricane. Try that on the LA area in
What else can we come up with?
