SEWER RETICULATION

The subject site is included within the catchment area of sewage pump station
NH17 which is located within the Noosa Springs Golf Course adjacent to the tee
of the 8 Hole. All the necessary sewer infrastructure has been completed
downstream of the proposed site. The existing sewer (Line No. 17/4) gravitates
from the existing maintenance sheds, along the eastern side of the 10 Hole and
then crosses the site from the eastern side in a westerly direction to the south

west corner of the site.

It is proposed to relocate this exiting sewer from MH17/4/5, across the 10h
Fairway then along the southern boundary of the development site to connect
again via a new manhole over the existing sewer midway between MH17/4/2
and MH17/4/1, as detailed on drawing No. C1732/07/J/P04. The new sewer
construction will service the allotments along the southern boundary of the
proposed site. A new sewer line will then be extended into the new allotments to
provide the required service connections. The new sewer network will require a
connection to the existing / new sewer with an invert level of 1.50m minimum.
The invert level of the existing sewer at the south west corner of the site is
approximately RI-0.45, this provides approximately 2.0m of additional depth

ensuring that the site can be serviced by the new sewer network.

WATER RETICULATION

The existing water network has provision for a watermain from Links Drive
adjacent to the existing golf course maintenance sheds. This watermain is a
150mm dia. main from Links Drive then splits into a 100mm dia. line to the
maintenance sheds and a 100mm dia. line extending towards the proposed

development.
