Engineering Evaluation Initiative

The Engineering Evaluation Initiative (EEI) is a $4m State Government election commitment to deliver better engineering approaches to manage salinity. Currently within the Wheatbelt nearly 1000 kilometres of drains are constructed each year to reduce the impacts of salinity. Many of these drains are poorly planned, designed, and constructed, and little is understood about their downstream impacts (from increased flow, increased stream salinity and high acidity).

The EEI consists of three main programs:

  • Evaluation of specific engineering options
  • Safe disposal
  • Regional drainage planning.

The main objective of the EEI is to review the current knowledge on engineering options to mitigate dryland salinity and to clarify ‘best practice’ by establishing demonstration sites for a range of engineering options.

Publications

All publications related to the EEI can be downloaded from the list below.

The Department produces a quarterly newsletter entitled Salinity Engineering that summarises the progress and achievements of this subprogram.

The Department has also published a short report, entitled “Reviews of engineering and safe disposal options SLUI 20” This report summaries the reviews of engineering, our current understanding and recommended work.

We have also produced a report describing the engineering options as tools for salinity management in the Spencer Gully catchment.

The Pithara site is one of four drainage projects being conducted by the Engineering Evaluation Initiative across the Wheatbelt. The main aim of the projects is to evaluate the usefulness of groundwater drains in reducing watertable and soil-salinity levels.
