Each day we interact with more devices which we call smart, from cleaning robots, to refrigerators or cars. And why not with the water supply? Connecting water monitoring devices to the cloud and operating them remotely not only allows us to control a device remotely, but also to compile data as needed to optimise its use.

For several years now, Hidroconta has been committed to the digitalisation of the water industry. An example of a successful project, this case study involves the digitalisation of a private drinking water network where water meters have been equipped with communications technology in order to visualise the data obtained with an easy-to-use application.

Located in the region of Madrid, the Urbanización Montealina housing development chose Hidroconta to carry out a digitalisation project

Located in the region of Madrid, the Urbanización Montealina housing development chose Hidroconta to carry out a digitalisation project. Specifically, Hidroconta has installed sensors in more than 400 monitoring points with its equipment, using the Sigfox 0G network of the development, providing communications technology through IoT to visualise the data obtained in a user-friendly app that the residents can use.

Montealina needs a system to control consumption given its characteristics: houses have large gardens and swimming pools, and the housing development itself manages its drinking water network with its resources.

This case study involves the digitalisation of a network: meters have been equipped with communications technology to visualise data with an app

The telemetry system installed has IRIS communications modules developed by Hidroconta which work, in this case, with the SIGFOX communication protocol and its 0G network. They transfer the data to our DEMETER web software and an APP for end users so they can control their individual household consumption, so that property owners can control instantly their consumption.

Communications protocol

The rationale for choosing the Sigfox protocol, a mature communications network, in this project is the good coverage that offers its 0G network within the Montealina housing development. Sigfox is the main provider worldwide of connectivity for the Internet of Things (IoT) and the creator of the 0G network. This network has already been deployed in 5.4 million km2 and 70 countries, connecting territories that are home to one-sixth of the globe’s population.

The rationale for choosing the Sigfox protocol in this project is the good coverage that offers its 0G network within Montealina

In the project to implement sensors in Montealina, the devices to be connected are located in cabinets mounted on the outside walls, something that helps with the coverage needed for IoT connectivity. On the other hand, the deployment necessary for installation is quick and easy, saving project costs.

Communications map

The Montealina urban water digitalisation project entails controlling assets, from the raw water and community network to the individual properties of water users. The project consists of four types of assets which have been fitted with an IRIS module to make them “smart”:

  • 1 meter at the outlet of the tank than controls consumption for the whole housing development. It is an electromagnetic meter.
  • 9 meters for district metered areas that control the units of the second phase of the housing development. They are Woltman-type meters, used to calculate a water balance and detect leaks.
  • 430 meters that monitor the water intake of individual properties. They are low-flow, multi-jet water meters that have been fitted with a reed-switch type pulse emitter and an IRIS device adapted to such emitters.
  • 15 meters that register water consumption in common-use gardens. In this case, they are also multi-jet meters with a pulse emitter and IRIS device.

All the devices communicate using the Sigfox protocol and its 0G network through the IRIS communications module. These devices transmit once per day and register consumption hourly. In addition, they integrate an alarm to detect leaks when consumption is constant. In this regard, water balances are carried out, both for the global water supply as well as for internal district metered areas. This enables studying any leaks in the network to improve the network’s performance.
