My wife and I are planning the build of a rural home in Hawaii next

cesspool system instead of city sewer, does the laundry, bath and
other grey water also go into the cesspool, or is there some other
treatment process for that type of wastewater.

It is possible to do it both ways. If you divert greywater you may be
able to get by with a smaller septic. I'm guessing that Hawaii has
very specific requirements which are strictly enforced.
