Wonder if the ground is warmer over drains.
The only guess I can come up with is: the presence of an impermeable
object (the drain) causes the soil in the immediate area to retain
more water, because the drain, unlike soil, doesn't allow moisture to
pass through. So perhaps just enough more water accumulates/is
retained in the immediate vicinity of the drain to enable the grass
roots in that area to benefit from that additional bit of water.
I've seen that with pavers that have sunk below grade, and have had
the grass grow over them. In prolonged dry spells that section of
grass will brown out sooner, but during periods of normal rainfall the
paver holds some of the water at root level longer, and the grass
grows thicker and faster over it as a result.
Some other possibilities:
The drain was put in later and backfilled with better topsoil.
The rest of the lawn is highly compacted and the drain area
The drain was put in later and the area re-seeded with
a different grass.
He could try fertilizing the whole lawn too, as that might
even out the growth rate, ie make the slower growing
grass grow faster. But it's only going to be temporary.
