The role EMASESA plays as an important environmental institution in the metropolitan area is evident particularly considering the following aspects: from supplying high quality drinking water to returning the polluted water to natural ecosystems. From its sanitation and treatment facilities, draining water into rivers during heavy rain via pumping stations to reducing river flows via storm water tanks. Both infrastructures are used to prevent floods.
Equally, the public nature of the company and the fact that a basic service is provided in the metropolitan area promotes the relationship with citizens, the administration and numbers of interlocutors. This translates into several activities which underline its corporate social responsibility.
In addition, the company has organised educational programmes for sustainability for over 20 years, through environmental activities like tours, talks, visits to schools and technical visits to educate the community and society.
