Spanish term or phrase: ranurada en la clave
Any landfill drainage specialists out there this evening, please?!
Many thanks

En lo que respecta a la zanja drenante, y aplicando el mismo procedimiento de cálculo descrito para la zanja de cabecera, se estima que los caudales que se infiltrarán hasta la capa drenante podrán ser conducidos por una tubería de drenaje de PVC DN315 ranurada en la clave (este tipo de ranurado tiene una mayor capacidad de transporte de las aguas y una menor capacidad de captación).

Explanation:
Ventajas para los operadores
-Buena afluencia de agua como resultado de una técnica especial de ranurado

Ventajas para los contratistas
-Bajo peso
-Ranuras perfectamente cortadas sin rebabas ni residuos en el interior de la tubería

Advantages for Operators
·Good water influx as a result of special slotting technique

Advantages for Contractors
·Low weight
·Perfectly cut slots without burrs or residues inside the pipe

Pipes are available in fully slotted, half slotted and solid wall options.

The slotted PVC or corrugated plastic pipes are laid at the base of a trench (slightly wider than the pipe itself) and back filled with permeable material almost to the surface This permeable layer intercepts the water flowing from upslope and delivers it into the large diameter drain pipe which carries the water to an outflow. This system prevents excessive upslope water from encroaching onto the flats.

Rows of water in-take slots are symmetrically arranged around the apex of the pipe (240°) with a flow channel at the bottom (120°). The high infiltration area combined with the thin inner wall structure ensures optimum water intake.

agree  TomWalker: "Slotted at the crown" is probably right. Not sure about "half-slotted" - size & configuration of slots will depend on the details of the application. There's a trade-off between infiltration capacity & conveyance capacity, as your last ref indicates.

  -> Some of the references I found refer to 'half-slotted', which was why I included the term. Thank you, Tom :-)

Tubería de drenaje corrugada de doble pared de PVC que corresponde al sistema DP, es decir, CON ranurado en la zona próxima a la clave del tubo.

http://www.tuyper.es/opencms/export/sites/tuyper/galeria_des...

In this context, 'clave' is usually 'crown' and looking at the diagram in the reference, there seems to be a couple of 'ranuras' in the position where the hands of a clock would be at 01.55.

Tubo ranurado is corrugated pipe but I don't think that works in this case.
