 S6    Treated Effluent Application Rates    M6.1 Irrigation may be via traditional trench, sub-       Not Applicable
       Effluent land application areas are   surface drip irrigation, surface drip, sand mound or
       sustainably sized and provided with   evapotranspiration-absorption wetland.

                                             M6.2 Application areas are sized and located with
       any adverse impacts on water

                                             Outcome S3.

                                             M6.3 An effluent irrigation area must be calculated
                                             (sized) to take into account:

                                             a) Soil type, texture and permeability;

                                             b) Climate conditions, including rainfall,
                                             evaporation and evapotranspiration;

                                             c) The rate of uptake of nitrogen, phosphorus and
                                             soluble salts in soils, allowing no leaching of
                                             nutrients to groundwater or surface water.

                                             M6.4 A reserve land application area of up to 100%
                                             of the effluent irrigation design area, is available on
                                             the lot.
