Last September 29 Mr. Maurice Ouzoulias, the President of the Interdepartmental Association for Metropolitan Waste Management in Paris (SIAAP), cut the ribbon on three new facilities at the Seine Aval plant in Achères. The Minister of Ecology, Sustainable Development, Transport and Housing, Nathalie Kosciusko-Morizet, was in attendance.
Bringing these facilities on line will help Seine Aval meet the regulatory standards set forth in the European Urban Wastewater Treatment Directive (UWWT), which requires elimination of 80% of phosphate-containing pollution and 70% of nitrogen-containing pollution. While the plant already complies with the phosphorous limits, the new equipment will enable it to reduce nitrogenous waste to the levels required by European regulations.
So, after two years of construction, these three new installations mark an important step toward improving water quality in the Seine River:
Nathalie Kosciusko-Morizet, the Minister of Ecology, Sustainable Development, Transport and Housing, was very pleased with the progress of the work. She congratulated SIAAP on the success of this project, which has enabled“the treatment plant to catch up, as the work done here takes it to a new level—from being merely an average player to being a leader—since the UWWT objectives have been achieved.”
Seine Aval is Europe’s largest wastewater treatment plant, handling daily over a million-and-a-half cubic metres of household and industrial wastewater as well as storm runoff.
BG is a long-term partner of SIAAP, having begun its work with the Seine Aval plant in 1995.
BG is part of the group responsible for designing and implementing UWWT compliance efforts. From 2003 to 2007, it helped construct the nitrification unit, the first stage in treating nitrogenous waste and the first phase of UWWT compliance.
From 2008 to 2011, BG participated in the second phase of UWWT compliance.
Finally, BG is a partner in the group responsible for implementing the new biological stream, which will begin in early 2012 with a 2017 completion date.
