I once did some math and rain water tanks around auckland(by far most common way to get water if you don’t have municipal source) cost less than the land that they sit under. My guess it might be similar to rotary dryer - the land under it costs more than lifetime of power your dryer will use. P.S. if you have lots of small kids then at some point hanging out tons of small clothing becomes an exponential chore.
