This gravity sewer will be redirected from Manhole NH17/4/5 to cross
the 10 Fairway (parallel to the relocated Rising Main and Effluent Main)
and then continue along the southern boundary of the proposed site to
reconnect to the existing gravity main midway between manholes

NH17/4/2 and NH17/4/1.

10.4 Existing Stormwater Drainage (Drawing C1732/07/J/P03)

The existing stormwater drainage crosses the proposed site in two
locations. At the northern end of the site the drainage collects water
runoff from the 11'h Fairway and Green and then discharges into Lake B at
the western side of the development. This section of drainage will be
taken up across the site and relocated north around the site and extended

again to discharge into Lake B.

The drainage crossing the southern section of the site collects stormwater
from the gully pits within Links Drive and continues west across the site
also picking up drainage from around the 10 Green and 18 Tee to

eventually discharge into the existing waterway south of the site.

This drainage will be taken up totally within the site and redirected to
extend down the proposed road corridor within the site and eventually

discharge into Lake B at the western side of the site.

This relocation will also provide additional treatment of the stormwater

flow by way of the proposed GPT at the discharge point into Lake B.

The Noosa Springs lakes system has been originally designed to ensure
non-worsening impact from the proposed development. This original

design includes the area of proposed development.
