Foundation Delfluent

The Delfluent consortium was established in 1999 to bid for the International tender launched by Delfland for the Design, Build, Finance and Operate (DBFO) contract including:

  1. The development of a new waste water treatment plant in Harnaschpolder;
  2. The refurbishment of the existing waste water treatment plant in Houtrust (The Hague);
  3. The management of both plants and the accompanying transport system with 18 pumping stations,  for a total period of 30 years.

After being selected as preferred bidder in 2002, the Delfluent company was incorporated in August 2003 and signed, on 5 December 2003, the DBFO contract with the Delfland Water Board, which remains, as local public authority, ultimately responsible for the quality of the waste water in The Hague region.
