Wallingford Software has installed its Info Works CS software with SIAAP, a major French collective in waste water management.
Wallingford Software has installed its Info Works CS software with SIAAP, a major French collective in waste water management Info Works CS provides water utilities with a tool with which to undertake hydrological modelling of the complete urban water cycle
SIAAP (Syndicat Interdepartmental pour l'Assainissement de l'Agglomeration Parisienne) will use the software to help ensure the success of its 25-year remit, which includes managing wastewater transportation, wastewater treatment and flood prevention, as well as maintaining the environmental quality of the Seine and Marne rivers for the greater Paris area.
The organisation required detailed flow information for Paris and suburban areas including Val-de-Marne, Hauts-de-Seine and Seine-Saint-Denis.
Its criteria for choosing software to achieve its aims included a requirement for high quality software and compatibility with systems used by the high level consultancies such as Prolog, Setude, Hydratec and Safege, which work for the organisation.
It also needed a system that would be compatible with existing software tools such as its GIS system, and that would be readily customised to meet its particular requirements.
For such a major public establishment, technical quality was more important than financial considerations said Wallingford Software.
It was also important for the software to have a French interface, and to be able to provide a two-year time series simulation, both of which are features available in Info Works CS.
The first model used by SIAAP was also from Wallingford Software.
Of importance to SIAAP was the fact that the public establishment's commitment to client service meant that it was on site from the beginning of the project.
Rene Dupas, director of Geomod, Wallingford Software's French distributor, said: "There is a confident relationship between SIAAP, Geomod and Wallingford Software and the company's software is already used by SIAAP's major consultancy partners." The 1,930 square kilometre Paris and suburban area, including Val-de -Marne, Seine-Saint-Denis and Hauts-de-Seine, has eight million inhabitants in all, producing three million cubic metres of waste water daily.
There are 2,350km of sewers in Ile de France alone, 160km of which are large diameter mains of between 2.5 metres and four metres in diameter, buried between 10m and 100m below the surface.
SIAAP's waste water treatment works include the massive Acheres plant, whose 2,100m cubic metres per day throughput makes it the largest in Europe.
Other notable plants include Colombes, at 240,000 cubic metres per day, Noisy le Grand at 30,000 cubic metres per day and the Valenton plant, which is being massively extended to take flows of 600,000 cubic metres per day by 2005.
SIAAP's extensive network of holding tanks and reservoir tunnels, ranging from the 165,000 cubic metre Stade de France to the smallest, the 15,000 cubic metre Proudhon facility.
That necessitates a flexible and comprehensive flow management capability.
Essential for identifying and justifying cost effective infrastructure improvements, Info Works CS also provides a practical method for operational control, including real time control, of waste water networks said Wallingford.
Other applications include urban flooding and pollution prediction and the modelling of water quality and sediment transport throughout the network.
As well as supporting network modelling, Info Works CS includes specific tools to support the modelling of sub-catchment take-off and infiltration said Wallingford.
Offering simulations, Info Works CS facilitates the swift modelling of total networks or any sub-network.
Users may now simulate models of up to 100,000 nodes with confidence that the results will be as accurate as those for far smaller models.
