It all depends on what injuries you have and any evidence. Did you take a picture of the drain or is it still in the way it was when you tripped up ?

Make sure you get as much evidence as possible to build a really strong case. Take photo's to court if need be to show the danger of the drain.

Good luck and enjoy spending your money.

my local council have admitted liability and i have had 8 months worth of treatment at hospital how much could i claim?
