The large wrench was used by the Wodonga Waterworks Trust and Sewerage Authority, which were established in 1897, and had the responsibility for providing Wodonga's drinking water and managing the wastewater. In 1923 a Wodonga Waterworks Trust referendum to provide funding for new infrastructure to supply more water of better quality to Wodonga was passed. This included building the Wodonga Water Tower and it was completed in 1924. It supplied water to Wodonga until 1959, when it was drained and decommissioned after the No 1 Basin on Huon Hill was completed in 1958. In 1983 the Wodonga Waterworks Trust and the Wodonga Sewerage Authority became part of the Wodonga Council. And by 1989 a filtration plant at Huon Hill was completed, which provided filtered water of improved quality to Wodonga, in accordance with the World Health Organisation’s guidelines. In 1994 the Kiewa Murray Region Water Authority took over the Wodonga Council’s water and wastewater operations, and then in 1999 the Kiewa Murray Region Water Authority combined with the Ovens Region Water Authority and became the North East Region Water Authority or NERWA. NERWA then became known as North East Water. The large spanner has local significance due to its use by the Wodonga Waterworks Trust and Sewerage Authority, and donation from the North East Region Water Authority. It also has wider historical significance as an example of the equipment used in the management of water in Victoria and Australia.Large cast iron spanner with some red/brown rust corrosion and light brown ingrained surface dirt.north east region water authority, nerwa, wodonga sewerage authority, north east water, n.e. water, wodonga, large spanners, spanner, wodonga waterworks trust
