He also mentioned something about green above-ground covers, but ours is still a grey tubey thing.
I do notice some in our street have had their grey tubey ones replaced by the light-green boxy one.
Why just some and not all I do not know.
On the original builds all the microduct laterals (the single ends) were installed up into the rectangular Green Boxes (known as Pedestals or PEDs).
On later builds only those that would end up in hard surfaces (footpaths etc) were brought up into PEDs and if they were to end in soft surfaces (grassed areas etc) they are buried (mostly right beside the grey terminals used for the copper connections), these are then dug up, when required, joined on and reburied.
Then on even later builds the PEDs have been replaces the Hand Holds (the below ground mini-pit with the round green lid) - those in soft are still buired but are now normal marked with a black Peg plastic peg with the Chorus logo on top to help with locating.
Our build has only just finished. We have no footpath so that would explain why we have retained the grey tube.
Did not notice a special Chorus peg though, must have a closer look over the weekend.
