Cross-connection control and backflow prevention
are not new concerns for water utilities. The US
Environmental Protection Agency (USEPA) is considering
regulation of drinking water distribution systems,
and one component of this regulation may
address cross-connection control programs. A
national regulation would potentially affect approximately
60,000 US community water systems and
nontransient-noncommunity water systems serving
fewer than 10,000 people.
The authors performed an analysis to assess the
potential cost of possible USEPA cross-connection
control program requirements. Potential regulatory
program elements that could be expected as part of a
water utility cross-connection control program were
identified, and a methodology was developed to provide
a transparent technical analysis of cost factors.
The methodology was applied to determine an order-of-
magnitude total cost that could result from comprehensive
adoption of cross-connection control requirements
for small community water systems. Insights
gained from this analysis are discussed to inform
assessment of national costs for future potential cross-connection
control regulations. Includes 15 references, tables, figures.
