--- title: "Water: specialized fields | Nexus Observatory" description: "Specialized fields for water and hydrology: River level and discharge, Rainfall and snow, Groundwater and Water quality." url: https://observatory.global/industries/water/fields/ publisher: Nexus Observatory Inc. updated: 2026-11-02 --- [Nexus Observatory](https://observatory.global/) / [Water](https://observatory.global/industries/water/) / **Specialized fields** # Water, field by field. Water is one cycle and many jobs. A river that floods a town, an aquifer that a region drinks from, a city's pipes that leak out of sight, a sewer that overflows in a storm and a lake that turns green in summer each need their own measurements, under their own rules, for their own people. Each field below sets out the stack, the radio, the power and the crew work, from the first order to the running operation. [Plan a deployment](https://observatory.global/contact/deployment/) [Use cases](https://observatory.global/industries/water/use-cases/) [Open the explainer](https://observatory.global/industries/water/explainer/) **01** Specialized fields ## Choose the field you work in. Each field page sets out the operating context and hazards, what must be measured and under which rules, the stack from base unit to network, the work from order to operation, the data products and the cited sources. [Specialized field Rivers and flood warningRiver level and flow, rainfall and cameras at gauging stations, flood forecasts and warnings issued by the authority, on links that keep working when the river rises.The full field →](https://observatory.global/industries/water/rivers-floods/) [Specialized field Groundwater and aquifersWater levels, salinity and abstraction in monitoring and production wells, on battery endpoints and LoRaWAN, for aquifer management, licensing and drought planning.The full field →](https://observatory.global/industries/water/groundwater/) [Specialized field Drinking water treatment and networksWater quality from source to tap, pressure and flow by district, acoustic leak detection and treatment plant monitoring, on secure networks kept apart from plant control.The full field →](https://observatory.global/industries/water/drinking-water/) [Specialized field Wastewater and sewer networksSewer levels and overflow events, pumping station status, treatment plant effluent and receiving water quality, to cut overflows and prove compliance.The full field →](https://observatory.global/industries/water/wastewater/) [Specialized field Lakes and reservoirsBuoys and profilers for temperature, oxygen and algae, inflow and level, satellite views of blooms, so water suppliers and lake managers act before a bloom closes a source or a beach.The full field →](https://observatory.global/industries/water/lakes-reservoirs/) **02** Solution bundles ## Start with one unit. Grow to a network. The same systems at every scale, on the open protocol, so nothing you buy is replaced as you grow. 1. **01** Base unit One station or node, specified for this industry: instruments, power, enclosure and backhaul. [Build a station →](https://observatory.global/studio/builder/) 2. **02** Site A surveyed, commissioned site with its timing, its links and the evidence file a buyer can audit. [Plan a site →](https://observatory.global/contact/deployment/) 3. **03** Fleet Many sites run as one service: one plan, one update path, one evidence trail, one service level. [Managed offers →](https://observatory.global/industries/water/solutions/) 4. **04** Network Fleets that federate with partner grids through the open protocol, owner by owner. [The open protocol →](https://observatory.global/protocol/) ### Ready when you are. Plan a deployment, configure a station or talk to sales. Every request reaches the team that answers it.
