Construction of the BOURGES wastewater treatment plant

Project

Location: Bourges – France

Type: Wastewater Treatment Plant

Subsidiary: GUINTOLI; EHTP; NGE GC

Work to install the first on-site crane marked the start of civil engineering work on this project.

A total of 3 tower cranes were needed to carry out all the civil engineering work required. Work on site began with night-time operations to lay around 550 m³ of concrete.

Once the earthworks were completed, the structure was backfilled as civil engineering work progressed and water penetration tests were carried out.

The underground pipeline networks were then laid using pipe diameters of up to 1 metre (GRP).

The NGE construction teams then handed over to the SUEZ plant operation teams to fit out the buildings.
