A computer model has been used to investigate
various options for disposal of separated water and
power station condensate from the Wairakei-Tauhara
system. In particular the effects of in-field reinjection
are compared with those produced by alternative
means of disposal. Our modelling results show that
infield reinjection reduces the useful life of the
resource and thus compromises its sustainability.
This is an important result as the policies and
regulations governing geothermal utilisation within
the Waikato region of New Zealand, which covers
the Wairakei-Tauhara geothermal system, are
currently being reconsidered as part of a notified
public process.
