about

The $25 million Eastern Irrigation Scheme is a joint project between Earth Tech and
Melbourne Water.

Under the partnership, Earth Tech designed and built Australia’s largest recycled water ultrafiltration treatment plant to supply Class A recycled water for the scheme.

Earth Tech also designed and built a 60 km pipeline network to distribute recycled water
to over 60 locations for horticulture, recreational, industrial and residential use.

The Eastern Irrigation Scheme operates under the brand TopAq, a wholly owned subsidiary
of Earth Tech. TopAq will own and operate the scheme for 25 years.
