Abstract: The Safe Drinking Water Act of 1974 mandates that EPA be concerned with the supply of potable water to the consumer. Although most emphasis has been placed on water quality as it leves the treatment plant interest in increasing in the role of the distribution system in causing water quality deterioration. In addition, distribution systems often account for 80% of total utility expenditures in drinking water. This paper reports on the research being conducted by the U. S. E. P. A. in the areas of cost modeling, development of systems for maintaining leak and break records and for assessing the probability of breaks and leaks occurring in distribution systems.
