Water and Sewer Lines
Test Development and Supporting Organizations

Development of the program was initiated in 1985 with technical guidance provided by the Engineering Department of the Washington Sanitary Commission (Laurel, Maryland).

Through a practice analysis, a volunteer panel of experts identified engineering technicians' job tasks and responsibilities and categorized them into work elements. Volunteers then submitted and reviewed examination questions for each of the work elements. The exam questions were then field tested through exams administered to technicians at varying levels of experience from the Washington Suburban Sanitary Commission (Laurel, MD), the Arizona cities Mesa and Phoenix, Pittsburgh, Pennsylvania, and Milwaukee, Wisconsin.

This program became operational in 1988. Technical guidance is currently provided by water and sewer line construction technicians, supervisors, and subject matter experts from a variety of stakeholder groups, including county and city agencies, metropolitan waster and sewer districts and agencies and private consulting firms.
