No public water, no public sewer
Large parts of Holmdel have no public water or sewage service at all. The zoning requires each principal building to have its own subsurface septic facility on the same lot, and communal sewage treatment is prohibited outright — which is also why the lots are as large as they are. If the property has a private well, New Jersey’s Private Well Testing Act requires testing at the point of sale.
