Rural homes here usually rely on private wells and septic
Buyers of rural property in a thinly populated county should expect a private well and on-site septic rather than municipal utilities, which carry their own rules and upkeep.
Outside Princeton and the small towns, a rural Mercer County home usually depends on a private well for water and an on-site septic system for wastewater rather than city utilities. That changes what you check before buying. A private well means you are responsible for testing and treating your own water, and the Department of Natural Resources and the Department of Health and Senior Services publish guidance on private wells and water testing. An on-site septic system has its own siting and maintenance rules, and DNR oversees on-site wastewater statewide while county health authorities often handle local permits. Before closing on rural property, find out where the water comes from, when the well was last tested, and whether the septic system is sized and permitted for the home. These are routine in farm country but easy to overlook if you are used to municipal service.
