station de dessalement
Hi,
Les forages refoulent l'eau vers une bâche de collecte des eaux brutes située à l'entrée de la station de dessalement dont la côte radier sera défini par le Constructeur.
"strike"??
Your help is highly appreciated
Thank you

Thanks to Clanola for posting "invert level", but strictly speaking a radier, in its meaning of "invert" is the bottom of a pipe, sewer, etc. Here I imagine the tank has a relatively broad, flat bottom (looking at no one in particular).
Radier works in French because the same word is used for a raft foundation slab and as such can be taken to signify the bottom or floor slab of a structure, in this case the tank in question.

INVERT LEVEL
(′in′vərt ′lev•əl)
(engineering) The level of the lowest portion at any given section of a liquid-carrying conduit, such as a drain or a sewer, and which determines the hydraulic gradient available for moving the contained liquid.

Some of the links Bourth gives in his previous answer do not work.
Here is another explanation:
Invert Level
This is a term that seems to have been specifically designed to befuddle students and others outside the trade, but is actually a much needed term for the sake of clarity on site. It refers to the height above/below a Benchmark of the lowest part of the pipe channel at a given point on the drainage system. The key point is that it refers to the level of the floor of the pipe on the inside, not the base of the pipe on the outside, which can be 10mm or more lower still, depending on the thickness of the pipe.
In a manhole or access chamber, the invert level (often abbreviated to IL), is taken to be the lowest point in the pipe channel that is still within the chamber, that is, the level of the pipe channel just as it exits the chamber.
The highest point of a manhole (or other access chamber) is the cover level (CL), which is the height of the cover above a benchmark level, and the difference between Cover Level (CL) and Invert level (IL) is the overall depth of the chamber. On drainage plans, manholes are often annotated with figures for IL and CL, and the difference between the IL figures for successive points of a drain run (usually manholes or other chambers) are used to calculate endfall.
(also a nice picture of a pipe showing the invert level)

Discussion
More definitions, this time from the Glossary of Building and Civil Engineering Terms published by the British Standards Institution.
invert Lowest point of the internal surface of a pipe or channel at any cross section.
invert level Level of the lowest internal part of the cross section of a conduit.
Since as far as I am concerned a tank of any kind is neither pipe nor channel nor conduit, anything with invert is an abus de langage unless it is known for fact that the floor of that tank is level with a pipe, channel, or conduit leading to or from it, i.e. the tank is is drained (or fed?) by gravity, not by a pumping via a pipe etc. at a higher level, and even if the tank and a pipe share their "invert level", if we are to say that, the term is only valid for the tank by virtue of metonymy, and I'm not altogether sure that has its place in technical texts.
(engineering)
The level of the lowest portion at any given section of a liquid-carrying conduit, such as a drain or a sewer, and which determines the hydraulic gradient available for moving the contained liquid.
It seems likely that we are simply taking about the level of the bottom of the tank (bâche) in which case both answers are actually correct and if this is so then better to stick with invert level.
Does that makes sense?
www.osmosistemi.com/index.php?option=com_docman...
which discusses a new desalination plant in Cyprus, states:
''A new seawater pumping station was erected adjacent to the original one, but at a lower invert level''. I understand from your posts (and mine) that the term ''invert level'' is to be used in reference to pipes, sewers, etc. whereas ''foundation slab level'' refers to tanks, building foundations, etc. If so, why is ''invert level'' being used here? Is it incorrect or am I reading it wrong (is ''pipe'' understood in the above document)?
The following doc. talks about the ''invert level'' of a septic tank:
http://www.wychavon.gov.uk/cms/business/town-centre-manageme...
So, what I need is clarification of when to use ''invert level'': with pipes, with sewers, and with what else?
Thanks in advance.
Anyway, just wanted to throw that in for anyone interested to know.
If we are talking about a tank and pipes, there could be TWO "invert levels", one for the (higher) feed pipe and one for the (lower) discharge pipe, the latter corresponding to or being below the bottom of the tank, unless the tank is pumped out.
However, it is also true that in my day to day use as civil engineer it is most definitely a foundation flab covering the complete surface of the structure it is supporting.
