Solving Simultaneous Risk Equations:
Waste Water Recycling And Fresh Water
Sustainability In An Arid Continent

Abstract
Two separate sets of entrenched environmental mal-practices in Australia have
created serious health risk issues. The risk equations are becoming clearer and
are interlinked. Solving one of these equations can assist in solving the other.
Equation 1: Major Australian cities have dealt with the growing human and
industrial waste water flows produced over the last century of growth by utilising
coastal proximity and piping partially treated effluent into the oceans. As the
volume and toxicity of the outfalls has multiplied, so have adverse health effects.
Equation 2: The mainly European settlers of an arid continent increased their
fresh water consumption at a prodigious rate. All major Australian cities are in
water supply crisis and irrigations schemes and depleted rivers threaten
agricultural sustainability. Tradeable water rights are to be granted to farmers but
it has become potentially unaffordable for governments to buy back sufficient
water rights to restore major river flows. Solutions: The Clean Ocean Foundation
established the campaign to \“close ocean outfalls” and invest in advanced
technology recycling of all waste water to standards suitable for an array of
agricultural and industrial uses, without health risks. Such an investment, which
would be well supported by urban populations, takes the pressure from river
systems and assists the affordability of water for farmers, industry, and for
environmental buy-backs schemes alike.
Keywords: water recycling, water policy, environmental risk, environmental
