action: dig around where the drain should be as if it's 1972, for any

assistance needed: then call on local experienced plumbers who may have
been to the home already, check with neighbors, and snake out ALL the
traps and drains.
a sewer camera isn't needed until after the above but you've already
got a major expensive water problem to fix so don't delay.
where the rain and dirty pool water all go could be interrupted by
blockage anywhere along the planned or real pathways of the drain. the
plans don't always match reality, so go with reality and a good sewer
man on this one.
often the oldtimers at the sewer company may provide assistance as to
how deep the applicable sewer can be found. a call to them may provide
a free visit to see that everything's fine on the city side at the
street manhole.


Good advice from BB. You may also want to call the local number for
utility locating, probably 1-800-dig-safe. Just tell them you are
doing major landscaping and installing a fence (when that car gets
moved). This is free and if the drains are iron they should find them.
If none of that works hire a plumber with a device for locating drains.
They send it down the pipe on the snake with a transmitter and use a
receiver to follow it. Probably expensive.
