As the Yarra became unsuitable as a source of water, several attempts were made to find alternative sources for the growing population of Melbourne. It was not until 1891 that the efforts to sewer Melbourne came to fruition with the setting up of the Melbourne Metropolitan Board of Works (MMBW), now known as Melbourne Water. From 1891 until 1992, it was the responsibility of the MMBW to safeguard public health by providing a sewerage system and a safe water supply system. In 1992, The MMBW merged with a number of smaller urban water authorities to form Melbourne Water.
The seal incorporates the coat of arms of Melbourne and the United Kingdom, and the motto of the board 'Publica Merces Salus Mea', 'Public Health is my Reward'. Text around the circular edge and in banners below two shields. The banners have leaves entwined. Above the two shields there is a kangaroo in profile beneath sun rays. One shield is part of the Coat of Arms of Melbourne and has a hanging fleece (top left quadrant), whale (top right quadrant), a bull (lower left quadrant) and a three-masted ship (lower right quadrant). The other shield is part of the Coat of Arms of the United Kingdom and has three lions passant (top left and lower right quadrants) representing England, a lion rampant (top right quadrant) representing Scotland and a harp (lower left quadrant) representing Ireland.
This MMBW key ring is of historical significance for its association with the former Melbourne and Metropolitan Board of Works (MMBW). The key ring is in a perfect condition and is significant as is represents a proud organisation and represents the organisations historical development of services, a strong theme of the collection. The key ring is aesthetically pleasing while the coat of arms holds great meaning.
