Petrac required that innovative and best practice techniques were to be
adopted for the development of “infrastructure systems to meet the
environmental goals of the proposed Eco-Tourism Portal. Given the sensitive
nature of the site, there was a requirement for full integration of the proposed
development within the site’s physical and environmental constrainis.

Below is a summary of the outcomes of each specific infrastructure
component.

Water Supply

Provision of water supply was considered by Cardno MBK as part of its
assessment of infrastructure provision (see Annex E: Noosa North Shore Eco-
Tourism Portal Infrastructure Assessment).

The remote location of the proposed Noosa North Shore Eco-Tourism ‘Portal
required the development of an innovative water supply system to service the
expected population whilst fulfilling the environmental goals of the proposed
Noosa North Shore Eco-Tourism Portal.

The proposed water supply system is to combine rainwater harvesting
(primary) and. groundwater extraction (secondary). It is intended that the
majority of the water demand will be met via a system of individual rainwater
tanks at the eco-cabins and a main rainwater tank at the lodge. A water
supply analysis has demonstrated that rainwater harvesting and storage will
be able to supply the visitor precinct with potable water at most times, other
than over extended dry periods. When specifically required, treated.
groundwater will be used to supplement potable water supply.

An optimal combination of rainwater and groundwater supply will be
devised through the development of a dynamic water network analysis
model. This analysis will ensure that the maximum potential yield from
rainwater is achieved, thereby minimising the impact/dependency on
groundwater extraction.

Sewage Treatment and Disposal

The sewerage requirements for the Noosa North Shore Eco-Tourism Portal
were considered by Cardno MBK as part of its assessment of infrastructure
provision. (see Annex E: Noosa North Shore Eco-Tourism Portal Infrastructure
Assessment).

A preliminary design for the proposed sewerage system was developed to
adequately service the proposed development and meet the environmental
goals of the Noosa North Shore Eco-Tourism Portal.
