Since 2005, Sacyr Water has been managing, through the Santa Cruz de Tenerife Public-Private Water Corporation (EMMASA), the total water cycle for the 209,000 inhabitants of the city of Santa Cruz de Tenerife: i.e., it is responsible for water catchment, desalination, treatment, distribution, sewers, purification, regeneration and management for the city's customers.
The facility has thirteen wells drilled to a depth of 36 meters along the coast and thirteen submersible pumps that extract the water from the sea before filtering it.
To carry out this essential work on an island where water scarcity makes it necessary to seek new sources of water, we have a multidisciplinary and versatile team with a common goal: supplying quality water to the people of Tenerife with the highest standards of efficiency and sustainability.
The excellent work being carried out includes modernizing and digitalizing the water cycle to reduce losses in the distribution systems and improve the wastewater treatment infrastructures. The improvements have included replacing the meters with electronic ones and installing sensors in the cycle to boost its efficiency.
The desalination plant is a benchmark infrastructure on the island thanks to its innovative system. This novel process employs an energy recovery system in which almost all the energy in the brine is recovered, which allows a better energy consumption ratio. The infrastructure has three reverse osmosis racks and, for every 100 liters of water we take out of the sea, 47 liters go to the drinking water supply. Thus, almost 60% of the water consumed in Santa Cruz de Tenerife comes from this desalination plant.
