Concern over Land drain ducting

On a new build estate getting a land drain installed in the garden. I'm concerned that the builder is using perforated yellow ducting (which indicates gas pipe) for the drainage. Is there any standards to state which pipe should be used? Also there is a lack of geotextile around the piping, should this also be used? Trying to make sure I'm not been done over

If it is perforated, it won’t be very useful for gas :)
Colour is irrelevant.
Depending on agreed specification, geotextile should encase pipe and gravel to stop soil contaminating them.

Hope this helps. Ta. John.
