Hello Andrew,

You should follow up with the installation company what the conditions of accreditation with the NSW Health requires. The relevant Australian Standard is AS1547-2012 so if you do not have a copy get a copy of that standard and look at the type of disposal area they are proposing. This system had a Wisconsin Mound. Below are the conditions for a s68 approval I have issued for an installation we had last year.

All the best with that Andrew.
