My husband and I are new to camping. We have a popup that has a sink, bathroom and shower. We don't have a gray water holding tank for the sink and shower (the toilet is self-contained) so we like to get a site with a sewer hookup if possible. We recently camped with a group of friends, some who were tent camping. We were placed in an area that was clearly geared for tent camping (majority of the RVs were located elsewhere) and all of the sites had water and electric. Since it was mainly tent campers I know there wasn't a "gray tank" anywhere to be found so I'm assuming that the tenters were dumping their soapy water on the ground or in grassy areas. Here is my question: Is it proper camp ettiquette to dump gray water on the ground? Is it OK for tenters to do this but frowned upon if someone in a RV or popup to does this? This could save us a couple of bucks at each campground if we didn't need a sewer hookup for gray water and just use the dump station for black water.
