[Nexus Observatory](https://observatory.global/) / [Water](https://observatory.global/industries/water/) / **Countries** # Water, country by country. Country notes for this industry: the regulators and the spectrum routes, from records that carry their sources. [Plan with us](https://observatory.global/industries/water/contact/) [Use cases](https://observatory.global/industries/water/use-cases/) Reference design, drawn to scale · drag to turn **01** Country notes ## Countries with a full record. Each record carries the regulators, the spectrum route for a private network and siting, with the source of every field.
