Cross-connection control and backflow preventionare not new concerns for water utilities. The USEnvironmental Protection Agency (USEPA) is consideringregulation of drinking water distribution systems,and one component of this regulation mayaddress cross-connection control programs. Anational regulation would potentially affect approximately60,000 US community water systems andnontransient-noncommunity water systems servingfewer than 10,000 people.The authors performed an analysis to assess thepotential cost of possible USEPA cross-connectioncontrol program requirements. Potential regulatoryprogram elements that could be expected as part of awater utility cross-connection control program wereidentified, and a methodology was developed to providea transparent technical analysis of cost factors.The methodology was applied to determine an order-of-magnitude total cost that could result from comprehensiveadoption of cross-connection control requirementsfor small community water systems. Insightsgained from this analysis are discussed to informassessment of national costs for future potential cross-connectioncontrol regulations. Includes 15 references, tables, figures.
