It's pretty common in rural areas to use wells for water, not have indoor plumbing, and essentially live in not much more than a trailer.
Yes, that is definitely an issue in developing countries...however you can see how we have developed since 1940
These Historical Census of Housing Tables: Plumbing tables are from the Decennial Census.
www.census.gov
"
In 1990, only 1 percent of our homes lacked complete plumbing facilities. But, things were much different in 1940, when nearly half lacked complete plumbing. Then, about ten States had rates approaching or exceeding 70 percent. In succeeding decades, the proportion of homes lacking complete plumbing dropped dramatically, falling to about one-third in 1950 and one- sixth in 1960. It is interesting to note the States with the lowest percent- age of such homes in 1940 were higher than Alaska, which topped the 1990 list.
Complete plumbing facilities are defined as hot and cold piped water, a bath- tub or shower, and a flush toilet. In earlier censuses, these facilities must have been for exclusive use of a housing unit's inhabitants; this requirement was dropped in 1990."
Note is says
HOT and
COLD piped in water.
That means 99% of the people in the US can do this...while in many countries people in cities can't even do it.
That also means we have this ability with our washing machines... again where in many countries people in cities don't have this.
While many in the US do use well water it is piped into their home system just like as if it was from the street...so they aren't running out with a bucket to some town square like you see in old stories/movies.

"17.7 million Americans Live in Mobile Homes which is about 5.6% of the American Population."
Plus limited access to services like healthcare, you can be driving up to 4-5 hours for doctor's appointments. The highway system is well developed that's true.
Again that is true for developing countries but we have solved that too.

"Rural Americans live an average of 10.5 miles from the nearest hospital, compared with 5.6 miles for people in suburban areas and 4.4 for those in urban areas, according to a new Center analysis. Taking local traffic patterns into account, that works out to a travel time of 17 minutes for people who live in rural communities, 12 minutes for those in suburban areas and 10 minutes for those in urban areas."
