The company AID was founded in 1928 to
protect the plain of the coal-mining basin from flooding
resulting from subsidence from mine workings. Seven local
authority areas were involved: Flémalle, Saint-Nicolas,
Seraing, Liège, Herstal, Oupeye, and Visé.
In 1976 AID became AIDE when it undertook the additional
task of sewage waste water treatment. It was incorporated
as a private limited company (SC).
Today AIDE designs, constructs and operates the sewage
and waste water treatment infrastructure for 79 local
authorities in the province of Liege - servicing about
1,000,000 inhabitants. There are 50 operational waste
water treatment stations in operation, with several under
construction. When the regional collective waste water
management programme is completed in around 2012, the
AIDE network will comprise more than 60 stations capable
of servicing 1,500,000 Inhabitant-Equivalents (IEs).
In 1977 the Capital C - Sewage Assistance agency was
created to assist local authorities in this sector. The
assistance provided also covers semi-private waste water
management systems undertaken within each local authority.
In June 2000, the three Liège Inter-Authority
Agencies operating in water and waste management activities,
AIDE, CILE and INTRADEL, took mutual holdings in each
other's companies to create an "Environmental Pole".
The aim being to actively reinforce the technical integration
of the three Agencies and to ensure an ongoing improvement
in its services to local authorities.
