Building Codes Queensland have issued the Advanced Enviro-Septic with Chief Executive Approval number 14/2014 for advanced secondary effluent quality.  CLICK HERE for the Building Codes Queensland link.


For designers, this means you will no longer have to attach the Alternate Solution documentation, but instead treat it as a standard application. You will still need to attach the AES calculator that has been certified by Chankar Environmental P/L (at and the Home owners manual.

All other procedures for the supply of AES products will remain the same. Namely the provision of confirmation of the Lic Plumber doing the installation and the sand being used.


** Merry Xmas to everyone **

We look forward to assisting you all in a Happy and Fresh New Year.

Our office will reopen on Monday 5th of January 2015.
