This paper promotes a holistic approach to wastewater infrastructure upgrading, and shows by the
use of an example project that aspects of a project can be linked to each other.
To deal with one aspect purely in isolation is to risk achieving a sub-optimal outcome, or at worst, an outcome where resources may have been spent on infrastructure that does not completely achieve important key outcomes.
This paper features a case study of the upgrade to the wastewater network, treatment plant and land disposal/reuse systems at Mount Isa to provide optimal financial value and reuse of treated effluent in a region short of water.
The overall project has provided value for the city by;
reducing overflow risk in existing overloaded trunk sewers.
increased capacity and enhanced quality to meet the terms of the existing Environmental Authority (EA) and new recycled water legislation enacted since.
(reuse by irrigation on city parks and grazing paddocks, or reuse by the Glencore mine).
