There is clean water in that pond, but there is dirty water in this one.

For avoiding repetition, What can be used to replace the mentioned uncountable noun"water"?

Thanks.

I think you will have to recast, qinqqinq:

'There is clean water in that pond, but it is dirty in this one.'

Thank you, Mister Micawber. But what about "He likes drinking hot boiled water, but I like drinking cold ..."?
I think I would say '...but I like drinking it cold'.
