Sewerage and reclaimed network


� Outdated graphic information, generally in a non-digitalformat.

� Difficulty in having quick access and updated data from thenetwork due to:


� Modifications caused by new road and railwayinfrastructures and service networks (water and gassupply).

� Modifications caused by town planning (new roads orstreets, new connections).

Modifications of pipelines due to works of the Baix Llobrega t highway



� Outdated graphic information, generally in a non-digitalformat.

� Difficulty in having reliable updated data from the networkdue to:

� Avoiding obsolescence: development of GIS required .

� Modifications caused by new road and railwayinfrastructures and service networks (water and gassupply).

� Modifications caused by town planning (new roads orstreets, new connections).

� In 2006 the implementation of EMSSA’s GIS began,contracting an ESRI ArcView licence.

Implementation of GIS

� Tool for inner management .

• Permanent updating and quick access to reliable

� Nowadays, the development is under way, having achieved agreat deal of objectives such as:

� Tool for Public Service :

• Maintenance of sewers and inflows and overflowscontrol.

• Providing precise and updated information.

• Providing on-line information (eWise- ACEFAT).
