House Project: Emergency Water Pressure

I think instead of relying on the ability to get gravity-fed water pressure from the cistern, it makes more sense to have the power panel include a plug for running an emergency generator. The scenarios that concern me about loss of electricity are:

1. Forest fire somewhere takes out power lines. This might be a couple of days without power.

2. Severe winter storm takes down a power line. This might be a few hours.

Having an emergency generator lets us flip the switch to disconnect from the grid, turn on the generator, and have enough power to run lights, well pump, and pressurization tank. The builder has built a house before that used a propane-fired generator as backup power to the solar cells and batteries, so he has done this before.
