Antenna Systems for Smart Wells

Purpose and goal

The project origins from the fact that there is a clear trend worldwide with increased requirements for surveillance of sewage networks. The VA companies thus need to be able to measure flows and emissions in real time and, in the next step, be able to proactively take actions. A well with a metal lid makes it difficult to transmit a radio signal from inside the well, and for practical reasons an antenna should not stick out from the well lid. The project´s main focus was therefore to develop integrated and cost-effective antenna solutions that can be fabricated in the existing casting process.

Expected results and effects

Two slot-type antenna designs have been delivered as results of the project, one of which meets certain sensor nodes´ eligibility requirements with two radio bands, while the other delivers a very advantageous radiation pattern albeit on one radio band. Single-band nets, i.a. with LoRa technology, are now being built in urban areas around Sweden to be able to use just such applications. A sensor node and a web interface have also been delivered into the project.

Planned approach and implementation

The project has been made up of a supply chain from well lid manufacturer, antenna developer, sensor node developer and community builder to a VA company. Parties who have complemented each other by contributing specific expertise in their field of activity; Antenna development with ShortLink´s many years of expertise and Tierp´s ability to fabricate different geometries. Sweco, like MSVA, worked on a more comprehensive level with "Smart Vatten” and contributed all kinds of input from their experiences and visions, while AquaDuctus delivered both a new sensor node and web interface.
