Plant some trees to replace the Poplar which was sucking up the water.

would be ideal but the poplar was on public land and would take years
to grow, vandals permitting. My garden is full of trees already.

Why not make a feature of it and make a natural pond, the overflow from
that you could route into the road drainage system, but it would always
be worth checking that it is a spring not a water leak from a pipe so
give the water people a ring and tell them they have a leak they will
soon tell you if its nothing to do with then!
