| DIR = = design irrigation rate in mm/week

Therefore:

qw = 3,367L (from Table 5.1.1) x 7 days

t = 23,569L/week

ro DIR = 20mm/week (adopted from Global
' Testing report in Section 3)

I Ai = 23,569/20 = 1,180m?

| Assuming the conservative DIR of
20mm/week determined above, a minimum

| of 1,180m? is required for irrigation.

| Drawing number HJ0085.1.5 shows the

proposed redevelopment layout and
proposed irrigation area locations.

© 4m from property boundaries, pedestrian
paths, footings of buildings, walkways,

For public health reasons the disposal areas
must have signage in accordance with
AS/NZS 1547:2000.

5.8 Additional buffer requirement

Further to the above recommended setback
distances the Noosa Shire Plan Planning
Scheme Policy 24 - Effluent Disposal
(effective February 3, 2006) requires that all
effluent disposal irrigation areas are to be
located not less than 100m from any
permanent or intermittent watercourse.

To this end it is proposed that the irrigation
area for this site will be located near the
western fot boundary to the south of the
access road, See Drawing No.HJ0085.1.6 (at
the end of this section).
