Greater Western Water (GWW) has successfully switched its geographic system map base to GDA2020 (Geocentric Datum of Australia 2020).

The change, which took place on 19th of February, ensures the alignment of the locations of building developments on GWW’s asset maps. The initiative is being led by Land Victoria and all Victorian water corporations are required to make the switch.

This project forms part of GWW’s program of work, aimed at transforming the way GWW captures, uses, manages and shares spatial information about its assets.

Supporting partners through the switch

GWW’s project team is on stand-by to provide any additional support its partners and contractors may need. GWW will support the submission of as-contracted plans in GDA94 to allow business partners to transition to GDA2020.

Please ensure all as-constructed plans submitted clearly state datum.
