Stunning architecture, a rich and diverse history and a 13th century cathedral lie behind León’s international reputation as a city brimming with culture and a great Spanish tourist destination.
The City of León
With a growing transient population in addition to almost 130,000 inhabitants and a historic quarter with a large number of nightlife venues, the city required a waste solution that:
An early model of the waste inlets is common in León, one of the pioneer cities for Envac in Spain. Barrio Húmedo, the old town.
The system is truly a part of the everyday life in León. The inlets are familiar to the citizens. Barrio Húmedo.

León is a place that is close to the hearts and minds of not just its inhabitants, but also those who take the time to visit it every year. As a result, preserving the site and retaining the features that makes León so special was extremely important to us.David Fernández del Río, Environmental Technician at City of León Municipality
After conducting a wide-ranging survey and planning programme, which established how the system could be installed whilst preserving the area’s historical infrastructure and architecture, Envac was retrofitted into a site covering 44,000 sq. m.
A total of 315 waste inlets, 75 of which are located throughout the entire historical district of Barrio Húmedo and 240 in La Lastra, make up the installation and connect to an underground pipe network spanning 3.2km in length.
Replacing multiple daily waste collections made by a fleet of waste collection vehicles, City of León’s Envac system quickly transports waste under the streets from the inlets to the system’s waste collection station, located on the outskirts of the city, in a new neighbourhood known as La Lastra. This means that waste collection vehicles no longer even need to enter the historical centre.
All but 111 of the inlets have collected the 2.2 tons of waste generated each day in León’s commercial and residential districts since the system became operational in 1999. The remaining 111 inlets have been installed and are currently waiting to be connected to additional buildings, which are still under construction.
In line with Envac’s commitment to ongoing development and as part of the City of León’s drive to ensure that the system is fully utilised, the municipality continually adapts the inlets to better meet user demand. Not only does this increase user engagement but it also improves the overall efficiency of the system.
Envac’s installation in León has:
Traditional waste collection in and around streets not capable of taking the pressures of industrial vehicles was damaging León’s infrastructure, posing a risk to residents and making the process of waste collection much more difficult for our waste collection teams.
Envac has provided a solution that ticks all the boxes by enabling us to have a 21st century waste collection solution in a 13th century urban infrastructure. Not only have we futureproofed our waste management strategy but we’ve also futureproofed the streets of León in the process.
