Water Pressure Excellent point! I'd completely forgotten. We normally have fairly high water pressure here. For the first 48 hours or so I didn't notice any change, then we started to see it decrease, and it was much lower by day 5. I assume that electric pumps are somewhere "up stream" and that they weren't working. Had there been some sort of real disaster or prolonged outage, I suppose we might have ended up without water.
Recently I've been involved in moving a radio repeater from one water tower to another, and I got told that city water isn't supplied by pumps, at least not directly. Rather, your water pressure is supplied by the mass of water stored in the area water towers. Water is pumped up the water tower, but your faucet pressure is passive. I would imagine in a power outage situation that the water in the towers would continue to supply passive pressure until the level in the towers got low.
