The WWTP will be built in a new location, though construction of a pumping station on the existing site will mean that current collection and discharge points can remain in use. The plant, which will serve San Antoni de Portmany and Santa Eularia des Riu has a construction period of 33 months.
Biological Treatment will be based on an activated sludge process with nutrients removal followed by a tertiary treatment for reusing the treated water. The sludge will be stabilized by anaerobic digestion and dewatered. In case of emergency the water could also be treated by a chemical process.
The new WWTP is designed to provide a high level of flexibility as well as low operational and maintenance costs.
