Sens technique

Directive 2000/60/EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy, commonly known as the Water Framework Directive (WFD). It sets out environmental objectives and deadlines to improve the ecological and chemical status of surface water bodies as well as the quantitative status and chemical status of groundwater bodies. Some water bodies created by human activity or having their characteristics fundamentally modified by human activity, may be designated respectively as artificial water bodies (AWB) or heavily modified water bodies (HMWB). In this case, their characteristics and ecological functioning are described by an ecological potential. The WFD especially sets the general goal to achieve "

Alteration

Sens commun

Change in the status of an aquatic environment or a river system causing degradation. Alterations are defined by their nature (physical, ionic, organic, toxic, biological, etc.) and their effect (eutrophication, asphyxia, poisoning, change in populations, etc). In most cases these alterations are due to human activities, but they can also be natural.

Pollution removal yield

Sens technique

Ratio between removed pollution and produced pollution. The pollution removal yield represents the effectiveness of the sewerage system of an agglomeration. It is equal to the multiplication of the treatment plant yield by the

Sens commun

Difference between the pollution produced and the pollution eliminated. Also referred to as "net pollution."

Gross load of organic pollution

Sens technique

For sanitation in an agglomeration, the sum of connected domestic pollution and industrial pollution. It is the daily pollution peak in dry weather. For industries, this pollution is determined by the water agencies using standard or measured coefficients, depending on the type of activity and the volume of activity. The gross load of organic pollution is defined by Article R2224-6 of the General Code of Local Authorities, such as the oxygen weight corresponding to the five-day biochemical oxygen demand (BOD5) calculated on the basis of the daily average load in the week during which occurred the highest load of pollutants in the year.

Eliminated pollution

Sens commun

For a wastewater treatment plant, the difference between treated pollution (measured input pollution) and residual pollution (measured output pollution). The pollution eliminated is determined by the Water Agencies through measurements or standard assessments in the peak month.

OSPAR Convention

Sens technique

Convention, signed in 1992, guiding international cooperation on the protection of the marine environment of the North-East Atlantic. It brought together and updated the 1972 Oslo Convention on dumping of waste at sea and the 1974 Paris Convention on marine pollution from land-based sources.
