VPRS 11570 Plans of Drainage (House Connections), Single-Number System

This series was created by the Melbourne Metropolitan Board of Works (M.M.B.W) VA 1007 and only includes plans that were transferred from the MMBW to Yarra Valley Water VA 4106 in 1995 when responsibility for water supply in the Yarra River catchment area was transferred from MMBW to Yarra Valley Water.All of the survey and plan records relate to the survey of Melbourne metropolitan areas subsequent to subdivision (for which, see records of Crown lands for survey, subdivision and sale/alienation). The function of the plans is to document the administration of water supply, drainage, and sewerage responsibilities.Plans of Drainage (House Connections) identify drainage systems and pipe installation for stormwater run-off. Plumbers use the plans for maintenance. Numbers were allocated when the property was built and every private property within the region covered by Yarra Valley Water has a unique property service number. The region stretches north and east of metropolitan Melbourne through the Yarra River basin.
