   Harvesting
                                                            Stormwater harvesting involves collecting, treating, storing
                                                            and re-using stormwater runoff from urban areas and is
                                                            considered to be a viable and cost effective alternative to
                                                            using local town water supplies. The typical stages of any
                                                            stormwater harvesting schemes are:
                                                            •     Harvest (stormwater is collected from the source)
                                                            •     Treat (to reduce pathogen and pollution levels)
                                                            •     Store (to retain stormwater for re-use)
                                                            •     Distribute (stormwater is distributed to the area of use)
