TNIS - Modernisation

About the Trangie-Nevertire Irrigation Scheme

The Trangie-Nevertire Irrigation Scheme (TNIS) evolved as a concept prior to the completion of construction of Burrendong Dam.  The underlying aim of the Scheme was to protect the interests of district landholders in the event of an anticipated Government endeavour to resume lands in the area for an irrigation settlement scheme.  When it became apparent in 1965 that the Government intended to allow private developers to take up and use the water rights available as a result of the construction of the Burrendong Dam, a group of landholders moved to form an organisation and seek an allocation of water to be used in an off-river irrigation scheme.

This group was known as the TNIS.  In 1968, the Trangie-Nevertire Co-operative Limited (TNCL) evolved as a separate legal entity to the TNIS, with each member of the TNIS having shares in the TNCL.  The success of these endeavours saw the start of a long and difficult job of organisation, and physical and financial administration in planning and constructing a system to serve 66 members.

Construction of scheme works began in 1970 and was completed in 1973.

Trangie-Nevertire Co-Operative Limited Modernisation and Rationalisation Project

Late in 2005 the TNCL Board of Directors recognised that a large number of challenges were faced by landowners within the TNIS area.  A long period of very low water allocations coupled with the wider effects of long term drought and little irrigation in the Macquarie Valley highlighted the need examine the long term viability of the TNIS.  This culminated in the completion of a Strategic Plan in April 2006 and the development of an Irrigation Modernisation Plan ready for publication in May 2009.

The TNIS Irrigation Modernisation Plan represents the initiative of the TNCL in their dedication to upgrading the scheme’s efficiency and production sustainability.  The Modernisation and Rationalisation Plan involves the following:

The TNCL have engaged Sydney based project management firm Farrell Coyne Projects Pty Ltd to oversee the implementation of the whole project.  

The life of the Project is four years and wil be completed in December 2014.
