    After discussions with Noosa Council Engineers, vT Consulting Engineers were advised that as
    the sewer and water supply are to be taken over by Unitywater as of 1st July 2014, the
    proposed sewer design should meet Unitywater standards and requirements. Unitywater
    advised that the water supply and sewer demand factors used in the table above are to be
    taken from the Maroochy Plan (2000) Table 2 (a) which Unitywater has advised is suitable for
    the design of the pump station.

    For more details of the sewer reticulation refer to the engineering plans in Appendix B.

    Internal house drainage design for this proposed development will be by others.
