Colony's Supply.
The catchwaters discharging through Lead
Mine Pass present no particular difficulties apart from
their being situated at a very high level and therefore
somewhat inaccessible. They should be put in hand while
the Reservoir is under construction, but are not so
urgent.
A Second pipe line should not be required
until the reservoir is almost completed, so need not be
considered at the moment.
The filters will be an extension of the
existing plant and should be dealt with early.
The
existing plant has been designed to allow of extension
when necessary.
