A mountain on the route<br />
In <strong>1999</strong> Sobea Île-de-France undertook work aimed at doubling<br />
the capacity of the pipeline system which catches water<br />
between the Vals de Seine and the Grande-Paroisse in the Seineet-Marne.<br />
This project includes the supply and trench laying<br />
of a sheetmetal-reinforced concrete pipe with a diameter of<br />
1,000 mm and a length of approximately 860 m. The route<br />
of the pipe crosses Tarpenton mountain with an altitude<br />
differential of 50 m and the laying of 15 pipes on a slope<br />
of up to 67%. In addition, work is being done to construct<br />
related civil engineering structures, a safety spillaway,<br />
a load-limiting structure and a gravel discharge structure.<br />

In the Paris region, Sobea Île-de-France was awarded<br />
the contract in <strong>1999</strong> to build two large collectors: one<br />
in Paris’s 12th arrondissement, the other at the Porte<br />
de Sèvres. It also doubled the capacity of the large<br />
diameter pipe which provides drainage for the Vals<br />
de Seine and la Grande-Paroisse in the Seine-et-Marne.<br />
Finally, Sobea Île-de-France has developed a technique<br />
which is unique in France: guided horizontal drilling<br />
which it has used on a number of construction sites for<br />
the Paris Airports.<br />
In the French regions, hydraulic engineering<br />
experienced a good year in which it won a number<br />
of large contracts related to the Orleans, Montpellier,<br />
Nancy, Strasbourg and Nantes tramway systems.<br />
1. Sobea Île-de-France<br />
supplied and laid<br />
a 1,400 mm diameter<br />
pipe at the Porte<br />
de Sèvres, in Paris's<br />
15th arrondissement.<br />
2. <strong>Sogea</strong> received<br />
contracts in the course<br />
of the year to perform<br />
major network diversion<br />
projects as part<br />
of the Orleans, Nancy,<br />
Montpellier, Strasbourg<br />
and Lyon tramway<br />
system projects.<br />
3. <strong>Sogea</strong> completed<br />
construction of the<br />
Valedeau drinking water<br />
reservoir in Montpellier.<br />
This structure has a<br />
capacity of 28,000 m 3 and<br />
is made of two 53 m<br />
diameter cylindrical tanks<br />
which are nearly 8 m high.<br />
4. <strong>Sogea</strong> continues to be<br />
one of the specialists in<br />
large diameter pipe laying,<br />
as here, in Avignon.<br />
A project carried out by<br />
<strong>Sogea</strong> Sud-Est.<br />
