A lot of work, which needs to be continuous and takes several years to make an impact. But if you want continuous use of a grass runway in the UK, necessary.

I am not sure that it is the grass which is the problem - more what is underneath.
The last ice age is the culprit for the whole of Northern England having an almost impermeable boulder clay sub surface which traps water in a thin layer of grass and topsoil. Further south where the ice didn't reach you still have the natural subsurface of chalk and surface water very quickly dissipates away. Effective draining of a grass runway which is on top of clay would probably be hugely expensive.
