摘要

In 1994, the National Small Flows Clearinghouse undertook the project of learning about the status of onsite systems across the country by contacting those in the local and state public health agenices who work with these systems every day. Approximately 3500 agencies were sent a questionnaire containing questions about onsite systems. The project objectives included determining the following for each state for the year 1993: the number of new onsite systems permitted; reasons for permit denital; number of onsite systems reported to have failed; reasons for system failure; new onsite system construction/installation cost; how often onsite system inspections are performed; and who has responsibility for onsite system maintenance.
