Pipeline Analysis, LLC is an engineering firm performing specialized sewer collection system testing and analysis. One-hundred percent (100%) of our business is associated with wastewater collection system inspection, testing and analysis. Principals and staff have worked entirely on wastewater collection system testing and evaluation projects across the United States since 1975. Pipeline Analysis, LLC owns all the necessary flow meters, confined space entry equipment, smoke blowers, closed circuit television inspection truck, etc to perform complete sanitary sewer evaluation and testing. Staff have are PACP (Pipeline Assessment Certification Program) certified.
Our staff has developed numerous improvements in the methods used to collect and analyze wastewater collection system data. Services provided by Pipeline Analysis, LLC include:
Since sanitary sewer testing and evaluation is our only field of endeavor, it is important to note that Pipeline Analysis, LLC performs field investigations and data collection in a very unique, cost effective manner. The following techniques used by Pipeline Analysis have enabled past and present clients to save on project costs while being provided with superior project deliverables.
Pipeline Analysis is a leader in the application of new methods that reduce field testing costs. The company's commitment to the use of new technology is demonstrated by the development of a "camera on a stick" that significantly reduces the need for confined space entry inspection of manholes. Our in-house manhole inspection device allows field crews to accurately measure pipe size, rim to invert depth all without confined space entry. Taking this concept one step further, Pipeline Analysis has applied digital picture capture which allows 
color photographs to be stored electronically. Storing photographs electronically allows them to be linked to the project database or incorporated into the Geographical Information Systems (GIS). Our software, that renames electronic photographs to match the manhole number, greatly simplifies linking photographs to database.
All project photographs are digitally recorded, linked to the database and provided with the project report. Area photographs provide detailed information on the pipeline cover and condition of easements. Internal photographs record manhole and pipeline conditions and are used to document observed defects.
Pipeline Analysis has designed and developed high capacity smoke blowers that are unique to the industry. Pipeline's blowers discharge up to 6,000 cfm while most commercially made machines discharge approximately 500 to 4,000 cfm. As a comparison, it may take two or more commercially made blowers to equal the pressure generated by a Pipeline blower. The key to locating inflow sources with smoke is pressurizing the sewer line. Pipeline's high capacity blowers provide greater pressurization, thereby identifying more inflow sources.
The use of Tablet PC's in the field provide immediate database entry, allows QA/QC queries in the field, and reduces project costs. The Tablet PC also allows digital photographs to be embedded into the field form and database.
Pipeline Analysis uses the latest technology to reduce project costs. Tools such as e-mail, multimedia project updates, non-proprietary software and CD-ROM reports are all currently used by our staff to graphically present the findings. Pipeline Analysis will provide a complete hard-copy final report as well as a report on CD-ROM. This final report will include all inspection data, the entire field database, graphics, written reports, leak sketches, photographs, video clips and maps in an electronic format. The CD-ROM final report will be a compilation of the various work products developed during the course of the project presented in one compact location. The data can be easily accessed and downloaded from the CD-ROM.
Wastewater collection system assets have a useful design life of approximately 75 to 100 years. Whether manholes or pipelines reach their useful life are to a great extent based on the materials of construction, soil condition, construction bedding, hydrogen sulfide concentrations, root intrusion, and sound maintenance practices. Collection system renewal is a continual process of finding system defects, prioritizing them and fixing them. The goal for the collection system manager may be to inspect the collection system on a 10-year cycle. (Note that critical sewers or those assets in flood prone areas may be on an annual cycle of inspection.) A ten year cycle will require inspecting/testing 10% of the collection system annually. The results of the inspection will generate repairs to manholes and mainline sewers. Private sector defects will also be identified requiring enforcement of local codes. Budgeting funds to find and fix system defects is the least cost solution to extend the life of the collection system another 75 to 100 years. Waiting for pipeline or manhole failure will require replacement of the assets which is the most expensive alternative (by several factors).
Collections system tools used to "find" defects include flow monitoring (to prioritize areas), manhole/pipe inspections, smoke testing, dye flooding and CCTV inspection.
Rehabilitation methods available to extend the life of collection system assets (renewal of assets) include trenchless technologies that minimize the impact to customers. Manhole rehabilitation may include lining, sealing, installing water tight ring and covers, raising buried manholes to grade, replacing vented covers, etc. Mainline sewer rehabilitation may include cured-in-place pipe (CIPP), slip lining and upsizing or pipe replacement by pipe bursting. These "fix-it" technologies are expanding to service laterals which must be addressed by collection system managers.
For example, the capacity analysis performed in the master plan will impact sewer system renewal. Knowing when a particular pipeline will require upsizing will impact the decision to rehabilitate the pipe. It may be more cost effective to defer rehabilitation (yet maintain the pipe) and replace the pipe as part of the capital improvement plan (CIP). Also, the least cost renewal plan may require deferring some rehabilitation until sufficient quantities are identified to reduce unit repair costs. Utilization of term contracts for collection system renewal is gaining favor as it speeds up the process of rehabilitation and fixes unit prices, thus keeping projects within annual budgets.

SUMMARY
Mr. Forbes has 34 years of experience in sewer evaluation projects involving temporary/permanent flow monitoring, manhole and pipeline inspection, smoke testing, flow isolation, CCTV, final report preparation, presentation of findings to City, State, and EPA, rehabilitation, Administrative Order negotiations, SSO abatement plans, computer modeling of collection systems, project approach development, and prioritizing rehabilitation recommendations. He has raised the standards for sewer system evaluation and analysis by implementing new analysis techniques and modifying equipment to optimize field results. Mr. Forbes' position as a nationally recognized expert has been garnered through his use of cutting edge technology for data collection and engineering analysis. Mr. Forbes pioneered the use of high capacity (4500 cfm) smoke blowers using mineral oil (instead of pyrotechnic smoke candles), use of GIS data visualization and linking of digital photos to project database, and implemented preparation of CD-ROM final reports.
He has served as project engineer on over 400 sewer system evaluations across the country, beginning with the earliest EPA 201 Facilities Plans conducted in the southeastern United States. Most recently, Mr. Forbes has assisted municipalities in preparation of EPA CMOM (Capacity, Management, Operation and Maintenance) Self-Audit Reports. He has instructed at various State short schools and seminars, and has authored numerous papers in the field of sanitary sewer evaluation and provided input and beta testing of manufacturers software.
Mr. Forbes was a co-author of the joint ASCE and WPCF Manual of Practice (FD-6) "Sewer System Evaluation and Rehabilitation" and served on the WEF Research Committee where he authored the annual literature review on Collection Systems. In addition, Mr. Forbes was a contributing author on the recently published ASCE Manhole Rehabilitation Manual of Practice. He is a contributing author on the CD-ROM Collection System Training Course under development by the Water Environment Federation and currently serves on the CMOM committee.
