The plumber recommended using the soakaway rather than the more awkward
problems I would have getting the drainage to the foul water drain. I
would tend disagree with him on gut instinct, as it might cause some
pollution problems.

Some plumber - did he come on a horse?

A pal did just this for both the washing machine and dishwasher, and
succeeded in causing damage to the foundations of his house which cost
large sums to fix. Of course I'd guess the soakaway was also faulty, but
putting large amounts of foul water into something not designed for it is
asking for trouble anyway.
