Gran Canaria Island Council tenders out €2.6 million Aquagran project to centralise water treatment and supply data

The Gran Canaria Island Council has opened a tender procedure for the execution of the Aquagran project, which will enable the implementation of a system to collect, monitor and manage data from all water infrastructures managed by the Island Council through the Gran Canaria Water Council.

The contract, which will be worth €2,650,000, has been tendered out as part of the Gran Canaria Smart Island initiative. The aim of the project is to upgrade existing sensors or install new sensors in rain gauges, treated water tanks, desalination plants, hydrants and other water treatment infrastructure currently without sensors or equipped with different sensor technology.

The upgrading and installation of these sensors at over 400 points will enable the Gran Canaria Water Council to collect real-time data from the entire Island Council network of infrastructures for water treatment or reuse. Until now, the Council has not had reliable data at its disposal because data collection and transmission from the water supply network is currently carried out manually and in a non-uniform manner.

The new system will be capable of capturing, transmitting, storing, processing, analysing and displaying global water management data. This will enable the Gran Canaria Water Council to monitor and obtain information. Other actors, such as university researchers and the emergency services will also have access to this information. Thanks to the Aquagran project, the Gran Canaria Water Council will automatically receive data in real time from all the stations it manages and this data will be displayed on a Geographic Information System (GIS). This system features a map of the island that includes all weather stations, rain gauges and water treatment facilities, amongst other infrastructure. With a simple click, it will be possible to see all the data with greater reliability and in electronic format.

Ultimately, the installation of this system will be of great benefit to the Gran Canaria Island Council in terms of: obtaining all the data in an integrated manner on a single platform, creating customised control panels for users, and monitoring how much water is being treated, how much is being returned to the sea and the quality of this water, etc.

Leak detection

The system will also enable the recovery of detailed historic data for specific dates and times. Therefore, it will also function as an alarm and detection system in the event of leaks, as data monitoring will enable the identification of substantial differences in certain parameters, which might be indicative of anomalous water consumption.

The Gran Canaria Island Council estimates annual energy savings of 7 GW and water savings of 1.2 Hm3 as a result of reduced water losses. This will translate into a financial saving of €1.2 million per annum.

Through the monitoring of the sensors installed in 66 rain gauges, two weather stations, 11 dams and reservoirs, 68 industrial water treatment infrastructures and 244 hydrants, amongst other points, the Aquagran project envisages serving 90 irrigation communities and 2,100 direct users of irrigated arable land. Moreover, the quality of 90% of treated water will be monitored.

Once the contract has been awarded, the project is scheduled for completion within a period of two years: 18 months for execution, and a further six months for training of Gran Canaria Water Council staff and commissioning.
