    3.3.1          Water

    The proposed development has an adopted Equivalent Person water demand of 530
    EP. The total area (excluding buffer zone) of the two allotments is 4.43 hectares.
    Assuming 20% is used for roads etc, the site has 3.54 hectares of developable area.
    Thus, the population density is approximately 150 EP/ha. From Table 3.1 (design
    criteria) the unit demand for water supply of 5.28 L/s/ha was adopted. The total
    Maximum Hour water demand from the proposed development site is thus 18.7 L/s.

    3.3.2          Sewerage

    The proposed development has an adopted Equivalent Person sewage loading of 470
    EP (142 ET), producing an Peak Wet Weather Flow (PWWF) of 4.9 L/s, at 3000
    L/ET/day in accordance with the adopted design criteria.

3.4 WATER SUPPLY RETICULATION ASSESSMENT
The SCRC Planning Scheme Policy 6 – Engineering Design Standards for Water &
Sewerage directs consultants to contact ‘Noosa Council Manager Water Supply’ for
hydraulic grades at proposed connection points. The following Peak Hour (19:00)
boundary conditions were extracted from Council’s Water Supply Reticulation Model.
