Stormwater Drainage
48.   Stormwater drainage shall be constructed generally in accordance with the report entitled
      “Stormwater Quality Management and Assessment Report” June 2007 by Callaghan and Toth.
49.   Final plans of the drainage design shall be prepared by a Registered Professional Civil
      Engineer and submitted to Council prior to obtaining a Development Permit for Operational
      Works.
50.   All stormwater drainage shall be collected on site and discharged so there is no net increase
      in stormwater runoff from the site.
51.   Roof runoff from any new dwelling shall be directed to a rainwater storage system or tank
      (minimum storage 3000 litres per dwelling/unit ) that is installed to ensure water from the tank
      can be used for external uses (such as watering gardens, irrigation, ornamental ponds, water
      features, topping-up swimming pools, outdoor cleaning, etc) and for use in flushing of toilets
      internal to the dwelling/building.  All rainwater tanks are to be designed and installed in
      accordance with the Queensland Development Code (QDC), Part 25 – Rainwater Tanks, and
      shall be part of the plumbing application in conjunction with the building approval. The
      location and capacity of the tanks shall be clearly shown on the plans submitted for Building
      Works approval.
52.   To ensure that polluted run-off does not enter Council’s stormwater drainage system,
      stormwater run-off from the carparking areas and the driveways shall have the first flush (the
      first 12 mm of rainfall or hose-down) collected in a grease/oil arrestor provided on site prior to
      being permitted to discharge into Council’s drainage system.
      All other clean stormwater, such as roof water, can be collected on site and discharged
      through a single underground drain line directly into the existing drainage system, bypassing
      the grease/oil arrestor.
      To this end, a detailed maintenance plan shall be prepared for the proposed grease/oil
      arrestors, which shall be submitted to the Council for approval prior to obtaining a
      Development Permit for Operational Works.
      The approved maintenance plan shall be incorporated in the Community Management
      Scheme for the development and a copy of this shall be provided for Council’s records prior to
      commencement of the approved Use.
      A Development Permit for Building Works shall not be granted until a Development Permit for
      Operational Works has been issued in regard to the drainage scheme.
53.   All site stormwater drainage shall be by means of a gravity system.
Sewer Mains
54.   The site shall be connected to the Noosa Sanctuary Development sewer reticulation system
      and be constructed in accordance with Council’s standards and requirements at no cost to
      Council.
55.   All sewage shall drainage by means of gravity to the sewage pump station located on lot 2
      SP110327 as per the Deed made on 22 December 1999 between Noosa Council, Aqua Blue
      (Noosa) Pty Ltd and the applicant, Johanna Jacoba Thannhauser.
56.   Should the drainage via gravity not be possible a new arrangement will need to be negotiated
      with Noosa Council
57.   The sewer system is to be kept and maintained in a condition suitable for use and shall not
      cause adverse impacts on the environment.
