# Controlling Extinguishing-Water Dampers in Disentis

LoRaWAN monitoring and control for remote municipal water reservoirs.

**Industry:** Public Sector\
**Organization:** Municipality of Disentis\
**Location:** Disentis, Switzerland\
**Year:** 2021

## At a Glance

| Measure      | Result                                                       |
| ------------ | ------------------------------------------------------------ |
| Connectivity | LoRaWAN without leased communication lines                   |
| Battery life | No replacement required since commissioning in 2018          |
| Maintenance  | Low effort through long transmission intervals               |
| Installation | Sensors can be placed flexibly without local WLAN or cabling |

## Challenge

Monitoring reservoir levels and controlling extinguishing-water valves is expensive in rural areas. Remote locations often lack power and network infrastructure, while dedicated fibre or copper lines can cost more than the sensors themselves.

## Solution

The municipality retrofitted its reservoirs with digital level sensors and IoT actuators connected to BuildingPro Suites through LoRaWAN. Operators can monitor fill levels and control the valves without installing leased lines or local WLAN.

Long, configurable transmission intervals reduce energy consumption. The sensor batteries have remained in service since commissioning in 2018, demonstrating the low-maintenance character of the solution.

## Benefits

* Remote infrastructure becomes economically viable to connect.
* Wireless devices can be installed or repositioned where measurements are needed.
* Multi-year battery operation reduces site visits and maintenance.
* Standardized end-to-end encryption supports use in sensitive infrastructure.

The project demonstrates how LPWAN connectivity can extend digital monitoring and control to locations where conventional communication infrastructure would be impractical.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.buildings.ability.abb/collection/success-stories/controlling-extinguishing-water-dampers-in-disentis.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
