Standardizing Pipeline Inspections

Fixing Aging and Often Neglected

The United States' aging piping infrastructure has been neglected time and time again. As environmental groups and regulators step up efforts to maintain the millions of miles of existing waste and storm water piping systems, the lack of industry standards has made it a challenge for operators and contractors alike.

The National Association of Sewer Service Companies (NASSCO) attempts to provide a basic foundation to an already disorganized industry in the Pipeline Assessment and Certification Program (PACP). PACP is the US industry standard system for coding defects and construction features from CCTV pipeline inspection video. Its' aim is to standardize a reporting and inspection format to help reduce or eliminate errors in miscommunication that may otherwise lead to the rehabilitation of the wrong pipe.

Reducing Costs Through Standardization

Most municipalities perform pipe inspections throughout the year and use that data to prioritize and schedule the following year’s maintenance activities. This could be a result of an unplanned rupture, blockage or other incident.

In the past, a municipality who has 500 miles of piping to maintain, may only inspect a small portion per year due to lack of internal resources or budget dollars. If a 10% annual inspection effort was made, the total piping system would take almost 50 years to complete. The challenge exist when you consider that over this 50 year span there exist employee turnover, changes to the administration affecting budgets, different contractors or vendors have been used, and methods, procedures or any other tribal knowledge lost.

NASSCO & PACP Software

NASSCO's PACP standardization eliminates these factors by providing a standardize collection and reporting format that is robust even in the presence of employee or contractor turnover. By following an industry standard, piping owners and operators can begin to evaluate the performance of its' rehab efforts using quantifiable metrics.

NASSCO was formed in 1976 to

improve the success rate of everyone involved in the pipeline rehabilitation industry through education, technical resources, and industry advocacy.

The fundamental goal of this activity is to ensure that PACP codes and their associated attributes are correctly implemented within video coding software, and more importantly, are cleanly exportable to other any other PACP certified software. This prevents any one software vendor from using proprietary features to lock competition out of the inspection market and force end users to purchase custom software to extract the value from those coded inspections.
