Attachment J - Sewage Treatment Assessment

Conclusion


A review of the Vipassana Centre Queensland Ltd occupancy rates and flow data has demonstrated that the
existing STP and land application area are suitable for current operations and meet the requirements of the
Compliance Certificate (Permit number 2003/118) issued by the Noosa Council in 2005.
Preliminary calculations of future hydraulic loading following the expansion of the Centre indicates that the
existing STP will require a significant upgrade or to be replaced and an expansion to the current land
application area will be required regardless.
The site assessment has concluded that there is sufficient area to support the increased land application area
and the soils can support the recycled water at the current irrigation rate of 25 mm per week, however
modelling via a MEDLI assessment based on site conditions to confirm irrigation rate and size is required.
An application to the Department of Environment and Science will be submitted for an Environmental
Authority, most likely an ERA 63 Sewerage treatment threshold 1(a)(i) – operating sewerage treatment works,
other than no-release works, with a total daily peak design capacity of 21 to 100EP, if treated effluent is
discharged from the works to an infiltration trench or through an irrigation scheme.
The application will be accompanied by a supporting document addressing potential environmental impacts
and management measures.
We trust that the details set out above are of assistance. Please address all enquires to either Michael Baynes
or Paul Wood on 07 53579169..
