When considering options to address channel seepage, options apart
from remediation techniques should be considered. This includes
consideration of asset management alternatives which may be appropriate.
Such alternatives which may be considered are:
Do nothing – It may not be worthwhile attempting
to reduce seepage if it is not significant, not causing detrimental
impacts,
or not cost-effective.
Remodel the channel – If the
channel is near the end of its useful life, seepage may be
addressed by remodelling
the
channel.
Relocate the channel – It may be possible to
relocate the channel to areas where soil types or other conditions
are more
suitable.
Rationalise or abandon the channel – Depending
on competing needs for water, the option to rationalise or
abandon
the channel
could be considered.
