Popis:	One of the objectives of a comprehensive domestic water use study conducted in Perth, Western Australia, was the quantification of components of water usage. Each household in a sample of about 3,000 was asked to record all water uses in a specially provided diary for a 2-week period, and the total water usage, both in-house and ex-house, was metered daily during this time. This article describes an application of Bayesian methodology to the estimation of usage for each in-house water-using activity for each house on each day of participation. The estimation procedure allows for inaccuracies in the diary records and incorporates prior information on the distributions of certain rates and volumes over houses. The prior information came from intensive data collection on a prior sample of about 150 households.
