filling over a water pipe in the kitchen?

[shorts]

Hi,

I’m having some work done in the kitchen and the sink has been moved. The mains water pipe that came up under it has been fitted with a smaller white pipe and a 90 degree turn, this is sat in a small gully dug into the concrete floor of the kitchen to under the new sink.

How should I fill this little gully with the plastic pipe in? Should I just fill it with self levelling concrete, sand and cement mix or something else?

Gully is about 2 foot long, 5 inches wide and bout an inch and half deep

Many Thanks

i cant fully envisage what you say but as mentioned...will this be seen. wont the kitchen unit hide it.
if it has any kind of joins in it (white=plastic?) then dont bury it
