Public water supply, urban wastewater management and municipal waste management are public services essential to the well-being, public health and collective security of the populations and economic activities, as well as to environment protection.
These services must respect the principles of universal access, uninterrupted and high quality of service and efficient and affordable prices.
As established in Law no. 10/2014, from 6th of
March, ERSAR is the regulator of the water and
waste services and the competent authority for
drinking water quality. ERSAR's activity aims to
ensure the guarantee and control of the quality
of the services provided as well as the
supervision of the prices, promoting the physical
and economic accessibility of the services. It also
aims to stimulate an effective public right to
information on the sectors and on each of the operators
In pursuit of its mission, ERSAR's conduct is governed by the principles of independence, impartiality and transparency:
ERSAR is an independent regulatory body in terms
of its organization, functions and financing. It is
not subject to government supervision.
In the performance of its functions, ERSAR treats
all parties with absolute impartiality.
ERSAR discloses a significant amount of
information regarding its activity and the sectors
it regulates, regularly reporting to the
Government and the Parliament. Furthermore,
ERSAR’s decisions are scrutinized by the courts.
