As a legacy of Muslim occupation during the Late Middle Ages, most of the fields in the Comunidad Valenciana region have a dense network of irrigation canals that have been improved and expanded throughout the centuries.
One of these canals, irrigation ditches or “Sequies” crosses Vila-real. Known as "Sequia Major“, it takes irrigation water from the River Mijares to the orange groves to the southeast of the city.
The irrigation services are managed by an organization - the “Sindicato de Riegos” - which maintains and manages the distribution system. This association is made up of farmers and holds periodic elections to designate its governing board. It is currently in the process of setting up an ambitious project to install a computer-controlled localized irrigation system throughout the municipal area.
