What does the FD do, with housing and no hydrants?

I'm no expert, but I can see the wharf hydrants at *every* home.
Here's mine, for example:

Plus, since we're in the most extreme fire hazard zone there is
in California, there's always a helicopter flying around which
can't but help notice the pool:

However, pool or no pool, it's my understanding every home is
required to reserve a huge portion of the bottom of their water
tanks, I believe, for that wharf hydrant.

For example, here's the bottom of "my" tank with the fire reserve
marked off at some point years ago where the outflow shuts off:
