Default Grey laundry water for garden watering?

I was hoping to get some advice regarding the use of grey water from
the laundry for garden watering - mainly lawns.
I'm not at all asking about the legality of it, which is not at all an
issue. Rather I am trying to find out whether or not the grey laundry
water is likely to stuff up my lawns. I use different sorts of washing
powders, switching between different brands, but I typically add:

NapiSan OxyAction MAX

Is this sort of grey water ok for lawn watering?
What if this grey water was used for deep soil irrigation near plants
and shrubs? (This is much less of an issue at this stage).
I really would appreciate some advice. Thanks.

There is a chap whose sig block is George.com from NZ and he has made up a
grey water system for watering his lawns. If you can attract his
attention he may be able to help you out with the necessary info.


don't drag me into this debate, I'm just an innocent bystander. I will
provide my expertise if someone answers my post about community gardens in
Sydney.

My experiments with waste water was limited to our summer drought. 4 +
months of fa water so I used the water from the washing machine on to the
lawn by way of a surge tank (old rubbish bin) and scavanged washing machine
pipe joined together with a gravity fall off the back deck. The system
worked well. I was initially worried about salt build up from the washing
powders. I brought some non-phosphorous powder but I also used some low(ish)
phosphorous powder as well. Upon reflection I was not too worried about salt
levels in the powder. My problem was a long drought by local standards. I
simply wanted to try and nurse the lawn through. 2-3 loads of washing
machine water a week was not enough to keep the lawn green but it did
mitigate some of the effects of the long drought. We have heaps of rain in
winter so salts in the soil will be washed through by constant rainfall.
Since mid april we have had roughly 3-4 inchs I guess. That is enought to
kick start growth and rains will continue through the winter. As a stop gap
measure it worked okish. year round however the salts in the washing powder
would worry me.

Now, if someone wants to answer my Sydney query:
Does nayone living in Syndey know of any community/permaculture/organic
gardens within the sydney city?

A woman from NZ is over in your city sometime shortly and is interested in
visiting such gardens to see how it is done.

Any contacts or websites is appreciated
