I think "bekken" is singular, so basin. Not the plural of "bek"

I wonder if this is a good internet reference:
And, there's no escape in sight. Along with the rest of the Atlantic storm basin, the United States likely has entered a long period of continuous active hurricane seasons

Hier in ieder geval een Belgische site over een stombekken:
http://www.kortenberg.be/overheid/gemeenteraad/verslag gemee...

Overwegende dat de HST-werken, vooral ter hoogte van Stationsomgeving, in de eindfase zijn;
Overwegende dat binnen deze werken een stormbekken is aangelegd;
Overwegende dat binnen de afsluiting van het stormbekken een elektrische voeding dient voorzien te worden, waarop een dompelpomp, een looplamp en kleine elektrische toestellen kunnen aangesloten worden;
Gelet op het principieel akkoord van het schepencollege en op onze brief d.d. 02 september 2002 inzake de aanvraag van de offerte;



Nog een:

Wat het stormbekken van Roodebeek betreft, is het zo dat
de bewoners van de Driesstraat opnieuw hebben moeten ondervinden dat hun kelders onderliepen na regenval die nochtans niet uitzonderlijk was.

Waitaminut, here is the right site:

Rainwater will be collected in a storm basin dimensioned to regulate the flows discharged into the natural environment. This basin, installed at the northeast of the center, will supply the inerting installation for Special Industrial Wastes and will provide the firefighting reserve.


The sneaks had hidden this answer by writing storm bassin instead of storm basin. Anyway, the site probably isn\'t written by a native English speaker

Flemish term (edited): stormbekken

This sounds like a soakaway, although I am not 100% familiar with the Dutch term. Maybe someone else would like to confirm or deny... Here's a definition of a 'soakaway':

-> "A soakaway is simply a hole in the ground filled with rubble and coarse stone with a drainage pipe laid to it removing surface (rain) water from other areas. The soil in which the soakaway is placed must be granular with good drainage properties. It is pointless sinking a soakaway in clay."
http://www.diydoctor.org.uk/projects/frenchdrains.htm

-> "Soakaways are probably the most common form of surface water disposal and are usually suitable for areas less than 100m2. Soakaways are generally formed from square or circular pits, filled with rubble or lined with dry jointed masonry or perforated concrete ring units.

Soakaways serving larger areas are generally lined pits, trench type soakaways or constructed from specialist proprietary units. It should be expected that a domestic rubble filled soakaway may need to be renewed about every ten years."
