In the course of the Millenium drought (2002-2009), the Labor Government spent $7b on a water grid & water purification & recycling infrastructure.
This infrastructure included the Bundamba Advanced Water Treatment Plant, designed to produce "Purified Recycled" Water from tertiary treated sewage effluent.
Currently, the Bundamba Advanced Water Treatment Plant provides a little bit of water to local industry, Swanbank Power Station and Springfield township. During the Drought it also supplied water to Tarong Power Station. Since 2011, Tarong has water to spare from its own catchment.
Neither the ALP or the LNP have any plans to utilise the idle water recycling infrastructure & stop the Councils or Council owned Utilities from discharging sewage effluent into the Rivers & Moreton Bay.
It is cheaper, more environmentally sound & climate friendly to recycle waste water than it is to desalinate sea water.
In the process of recycling water, one could recover the nutrients (Nitrogen, Phosphorus, Potassium, etc....) that are currently polluting the waterways. These nutrients could be used beneficially in agriculture.
In the light of this, let us have a closer look at the Liberal National Party's Water Policy. The LNP claim that Queenslanders are facing spiraling costs of living and family budgets are under severe strain because Labor can't get the basics right. The LNP Claim that there is no forward planning, Perhaps they have not read the South East Qld Water Strategy ....or perhaps they have, since the LNP Strategy looks very similar.
None of the above will have significant impacts on the bulk cost of water or retail price of water.
