Pressure Pipe vs. Gravity
Pipe Cleaning

Presented by: Joe Schotthoefer
Doetsch Environmental

Pressure pipe cleaning is not the same operation as gravity cleaning. This will be a comparison of needs and outcomes including why do we clean, is it able to be cleaned, what methods are utilized to clean, what is being accomplished, what does the final deliverable look like, and what to expect when specifying or contacting.

A fifth-generation family-owned business. Joe is the current President of the Board of Directors at NASSCO. Joe is a mechanical engineer by education, but field engineering specialist by trade. Joe crafted his skills on the shop floor, at the job site and in the pipe. He is responsible for the custom manufacture and continuous improvement of the company’s fleet of water recycling large diameter, long reach, difficult access and high-pressure pipe cleaning and debris extraction machines.

Class I The Original Trenchless Technology: Cement Mortar Lining

Presented by: Chris Walsh
W. Walsh Company Inc.

 A description of the purpose, and the means and methods to cleaning cast iron potable water pressure mains and lining with cement mortar.

One of three brothers in the second generation of W. Walsh Company, a small family business focused on cleaning and cement mortar lining of water mains. Chris is active in American Water Works Association, chair of task group C-602, AWWA Standard for In-Place Cleaning and Cement Mortar Lining.

Class II & III Rehabilitation of Pressure Pipelines Using Polymeric Linings

Presented by: Joanne Carroll
Subtegic Group

Epoxies, polyurethanes, polyureas and hybrid versions of these polymers have been used to protect and rehabilitate water mains and force mains for decades. Polymer chemistries have evolved as well as systems developed that enable the application of these polymers to address prevalent issues of aging water infrastructure in the most efficient and effective ways. This presentation will expand upon the capabilities, application processes, design considerations, and pressure pipe lining classification of polymeric linings today. The goal of this presentation is to broaden awareness of their unique capabilities and relating them directly to the selection and specification of these systems for rehabilitating pressure pipe.

Joanne Carroll has over 30 years of experience in the trenchless industry, including 18 years with a major polymeric lining manufacturer and 10 years leading a CIPP system provider until starting Subtegic Group Inc. to provide consulting services on the rehabilitation and protection of buried infrastructure using trenchless technologies. Joanne is a NASSCO ITCP Trainer for both CIPP and Manhole Rehabilitation.

Utility Project Management

Presented by: Gary Moore Sr.
Bryant Associates

In this presentation, there will be a discussion of setting up a project, identifying all the requirements, working through the engineering design using the established individual project dynamics, and what the thought process is while compiling the contract documents to convey the intent of the client to the contractor in the most appropriate format.  

Mr. Moore has extensive expertise in the civil engineering field, from both the public and private sectors. This has been a blended experience that began with government service as a public official, included owning both a construction firm and an engineering firm performing engineering services for municipalities and utility companies along with commercial and residential clients, and has worked for engineering firms providing energy, solid waste, water and wastewater consulting services for predominately municipal/government clients in the US and worldwide.

Class III FFRP for Pressure Pipe

Presented by: Rick Gage & Jonathan Raymer
MTC/Aegion & Federal EC


Failing pipes that are under constant pressure can be rehabilitated with an innovative, proven trenchless technology that utilizes a high-strength, aramid fiber-constructed tube. FFRP is constructed in layers consisting of polyethylene and Kevlar. It can negotiate 45- and 90-degree bends and has been installed in 6-inch through 24-inch pipes in lengths of 50 feet to 9,000 feet in one pull. Pressure pipes that are being renewed with this economical technology transfer potable water, processed water, and sewage.

Rick Gage is a Senior Business Development Manager for Aegion/MTC. He has over 15 years in Trenchless Technology. Rick is a MSTT Board Member, a Member of ASTM, and a Member of NASTT

Jonathan M. Raymer P.E. is a licensed utility contractor, general contractor, and professional engineer. He has been working in the trenchless technologies industry since 1998. He is currently the General Manager and owner of Federal Engineering & Construction (Federal EC LLC) based in Atlanta, Georgia and specializes in the inspection, cleaning, and rehabilitation of underground piping.

Class IV Bursting, Slitting, and Lining

Presented by: Alan Goodman
Hammerhead Technologies

This presentation will review the current methods of water, sewer, and gas pressure pipe replacement by means of pipe bursting or pipe splitting. Addressing some of the differences between main and service line replacement with emphasis on different pipe materials being replaced and installed. The other portion of the presentation will focus on CIPP for pressure pipe and fire main applications. A few case studies will focus on the above mentioned methods and obstacles to address and overcome.

Alan Goodman has more than 20 years of experience in underground and trenchless construction. He is the current chair of NASTT and the Sales Manager for HammerHead Trenchless® looking after the US and Canada. Goodman’s experience includes directional drilling, pipe ramming, auger boring, pipe extraction, pipe slitting, pipe bursting, and cured in place lining. Alan has worked with municipalities, gas utilities, engineering firms, and contractors around the country providing customer training, technical support, pre-project planning, project specifications to support trenchless rehabilitation and new installation.

Class IV Internal CIPP Water Service Reinstatement Advancements

Presented by: Steven Soldati

We will focus on advancements to the method of internal service reinstatement using a mechanical seal that is inserted into the service after lining. It is the evolution of a system introduced a decade ago, where a hollow stainless-steel bolt is threaded into the opened service after lining. The concept was revisited with the cooperation of a robotics firm, resulting in a more effective mechanical insert and more effective tooling required to robotically install the insert. The system has undergone significant testing with respect to the ability to withstand vacuum, as well as the expected pressures in a water distribution system.

Steve Soldati is a registered civil engineer in Florida and California. He attended the California State University, Chico, where he earned his Bachelor of Science in Civil Engineering. He has over 13 years of industry experience working in construction, sales, business development, project & program management for both the private and public sectors. He currently serves as the Commercial Manager of Pressure Pipe for Aegion Corporation and delivers innovative, technology-based solutions for the water and wastewater industry.
