wastewater design

1.00 INTRODUCTION

In accordance with the relevant codes, standards and Noosa Councils guidelines,
Unearthed Geotechnical P/L was commissioned to undertake a Site and Soil
Evaluation at Lot 2 SP241381 Sister Tree Creek Road, Kin Kin.

The results form the basis of our recommendations for the on-site treatment and
disposal of wastewater from the four proposed one bedroom cabins on this 21.5
hectare rural allotment.

A representative of Unearthed Geotechnical P/L was met and shown to the proposed
site by the owner, J Williams. Our site investigation fieldwork was performed on

31/01/2022 after some recent seasonal storm/rain activity in the course of the
preceding weeks.
