When Kula needed water to stop wildfire, it got a trickle...

[Fred Bloggs]

Many other US cities are also vulnerable

This is another major headache in the making, it will be a requirement for climate resiliency.

Of course they\'re jumping on diesel backup generators, but it could be biodiesel or a synfuel, not necessarily petro-diesel. Whatever they select, it should have a long storage life.

One way to conserve water in an emergency is to shut the users off. Apparently almost all the smart water meters have remote shutoff capability, it\'s quite a money saving feature ultimately. The question is where do the meters get the power to do this: 1) mains derived power, 2) battery power, 3) water pressure power. Obviously only 2) is going to work in an emergency catastrophe scenario.

The idea of using satellite communications to transmit meter status in real time is brilliant. That will work except in times of a supervolcano eruption.

very stupid idea

what matters is water retention (Nobel Prize)
and reduced use of tap water,
so smart water meter should work 2 modes:

1. full shutoff
2. reduced water flow

So the marketed product represents an old 1-0 logic technology
and should be replaced by fuzzy logic gear

1.0, 0.8, 0.5, 0.3, 0.1, 0.0
x water flow

I\'m not sure there is such a thing as reduced water flow. The idea is to keep the pipes pressurized. Reduced flow means reduced pressure.

The shutoff scheme would work the same as rolling blackouts.

They can\'t do much by way a fairly high duty cycle on/off\'s at the meter, as they might run down the batteries. They can certainly permanently shut down a meter reporting excessive non-stop use, indicating possible damage.
