Earthing on a black bag landfill

Earthing on a black bag landfill

Earthing on a black bag landfill

(OP)
A client wants to build a new works on a disused landfill. There will be a number of 11/0.415KV substations on site.

FYI - there will be a 1-2m aggregate capping layer and hardstanding.

Does anyone have any experience of how to approach the earthing in such a situation?

RE: Earthing on a black bag landfill

With everything sitting on a big insulating plastic layer, seems like it will be bonding rather than grounding. Be sure to include plenty of mechanical flexibility to allow for significant settlement as the garbage decomposes.
