PIPELINE CONDITION ASSESSMENT
America's Sewer Infrastructure Challenge
In 2013, the American Society of Civil Engineers' (ASCE) Report Card For America's Infrastructure rated the nation's wastewater and stormwater sewer systems with a grade of D. The ASCE has estimated a total of $298 billion in capital investment will be needed over the next 20 years to restore America's sewer infrastructure. Pipes represent the largest capital need, comprising three quarters of total needs.
Pipeline Inspection and Assessment Services
For pipeline systems installed before 1980, it is not uncommon for defects to develop within the system which may be a product of all or one of several contributing factors including natural weathering, geotechnical forces, chemical degradation and man-made events. Defected pipeline systems when left unaddressed can lead to potential flooding issues and environmental pollution. WRMA has assisted property management firms, facility managers and major municpal agencies, by providing detailed inspection services for sanitary and stormwater pipeline systems.
Closed Circuit Television (CCTV) Inspection of Pipeline Systems
WRMA's engineering team provides comprehensive condition assessments of sanitary and stormwater pipeline systems through closed circuit television inspections (CCTV). During a CCTV inspection, a specialized robotic rover is inserted into the pipeline system. A small custom built high definition camera mounted to the robotic rover captures HD quality footage of the internal surface of the pipeline, recording defects along the entire alignment of the pipe and manhole. Once this footage has been collected, WRMA's NASSCO certified engineers analyze the data to determine the severity and frequency of defects along each pipe. For seriously defected pipes, WRMA can provide reccomendations for pipe rehabilitation, repair or replacement.
