SADE is designing and building a dewatering system for Eiffage Immobilier

The aim of this dewatering system is to transport water from the water table lowering system set up on a gigantic urban redevelopment site in Asnières-sur-Seine, not far from the River Seine (of course), a further 390m to join a wastewater system operated by SEVESC.

An overhead system

This gravity system features 12m steel tubes (Ø 300 and 400) installed at an average height of 4.5m on hangers designed by SADE Ingénierie. The facility’s 37 hangers, each weighing around 10t, were built on public roads, mainly along Rue Henri Bergson and Rue Louis Armand.

Custom hangers

The hangers are custom-built, featuring from bottom to top, a concrete base, a vertically-installed concrete duct commonly used for wastewater treatment (Ø 1,200 / height 2.40m), into which a ø 350 steel tube, meticulously laid to follow a 0.5 to 1% slope, is inserted vertically and cast in concrete.  The whole system is calculated to absorb the forces generated by a maximum flow rate of 454m3/h.

A conditional package?

This first, firm package, requiring a 5-person team, will be delivered at the end of June.  A conditional package covering approx. 300m is in the planning stage. So watch this space…
