Pipeline Condition Assessment: Devil Is In The Details

Speaker: Lisa Douglas, P.E., Division Manager, Carylon Water Group


De Soto, KS, wanted to investigate a pressure differential in a critical raw water main asset running beneath the Kansas River. This 16-inch, ductile iron main represented a high-priority asset due to its age and function. Concern was that a partial collapse of the buried pipeline, leakage, blockages or internal build-up had occurred. Before an internal inspection tool could be launched, a 120-psi water jetter nozzle with blades was used to cut and spray out the sediment that had solidified in the main. Additional cleaning of key portions was still necessary after the initial work.

Success Story: Euless, TX, Water Conservation Planning, Reclamation

Speakers: George Farah, P.E., Alan Plummer Associates Inc.

Hal Cranor, Engineering Department, City of Euless


As a partner in the Region “C” State water planning team, Euless, TX, leadership understands the challenges of regional water supply and demand. Employing a proactive approach to water shortages in north Texas, the city prepared a conservation plan using water from the Fort Worth Village Creek Water Reclamation Facility. The Euless Reclaimed Water System includes a storage pond, pump station, and distributions system of 12-inch and smaller pipelines. This presentation will cover the overall history and expansion of the system, and review several design constraints and various technologies used for this project.


9:30 – 9:55 a.m.

IDIQ Contract Success In Corpus Christi Water System

Speaker: Brent Lindelof, P.E., Regional Sales Manager, Underground Solutions Inc.


The city of Corpus Christi, TX, implemented a unique methodology to rehabilitate and revitalize its water system – an indefinite delivery, indefinite quantity (IDIQ) contract that facilitated improvements at a program level. This presentation will focus on three of the projects installed as part of this IDIQ contract, where an open trench was not an option. Trenchless methods, including HDD and pipe bursting, made it possible to span the channels within the Corpus Christi marina, cross the heavily trafficked Texas State Highway 358, and rehabilitate approximately 3,700 feet of 4- and 6-inch cast iron lines running through residential backyards, with minimal impact.


10 – 10:25 a.m.

NO Water Main Replacement With Compression-Fit HDPE Lining, Bursting

Speakers: Mark Bear Child, Project Manager, SWBNO

Todd Grafenauer, Education Director, Murphy Pipelines

Bart Peak, Vice President of Operations, Wallace C. Drennan


Using an innovative approach geared towards reducing customer impact, minimizing capital spending and reducing operational costs, New Orleans Sewerage & Water Board selected pre-chlorinated pipe bursting and compression fit HDPE pipe lining to install new HDPE pipe. This included replacing 12-, 16- and 30-inch water mains in sensitive urban areas with busy intersections and along Tulane University, requiring fast construction completion. Wallace C. Drennan, a third-generation Louisiana construction company, and Murphy Pipelines, which specializes in trenchless technologies, were awarded the projects.


10:30 – 10:55 a.m.

World’s First Installation Of 36″NSF 61 UV CIPP: Project Challenges, Lessons Learned

Speaker: Mike App, Senior Project Manager, Precision Trenchless LLC


Since created by cast-in-place concrete from 1905-1910, the pipeline’s 2’ sections have carried water from the Barker Reservoir outside of Boulder, CO, and delivered nearly 80% of the city’s drinking and agricultural water. This presentation will cover the scope, challenges and lessons learned of a demo project to determine the viability of using CIPP, especially UV Cured Fiberglass CIPP, in a gravity system of 36” pipe, with twists and turns, from the 8,500’-elevation reservoir, down 3,000’ to Boulder. Also, the right-of-way access was only 12’ wide, each segment was nearly 500 LF, and work was restricted to the month of March.


11 – 11:25 a.m.

Regional Approach To Expand Water System In North Dakota

Speaker: Richard (Bo) Botteicher, P.E., Vice President and General Manager, Underground Solutions Inc.


North Dakota is building infrastructure in the northwest to meet growth trends. The Western Area Water Supply Association (WAWSA) was enacted by the state legislature to ensure a cohesive approach to this expansion, with the goal of providing water to five counties: Burke, Divide, McKenzie, Mountrail and Williams. Construction is funded in large part by selling excess water to the energy industry, which prompted the area’s development. This presentation will discuss the multitude of installation methods, both open trench and trenchless, as well as pipe materials used to expand the water infrastructure for the growing population.


11:30 – 11:55 a.m.

Protocol For Structural Classifications Aligns Rehab Problems With Lining Products

Speakers: David Kozman, P.E., Product Manager, HammerHead Trenchless

Christopher Macey, P.E., Americas Technical Practice Leader-Condition Assessment & Rehabilitation, AECOM


The AWWA M28 sub-committee on Structural Classifications has developed a suggested protocol to align structural lining with rehabilitation systems. The approach associates the various types of deterioration problems to specific rehabilitation products, and outlines testing regimens that quantitatively define each unique classification. Also, an industry-consensus overview on the design of structural lining systems is based on the concept of rationally matching the approach to the product, its limit states, interaction with the host pipe, and the overall rehabilitation objective. This session provides an overview of the Structural Classifications white paper and its roadmap for further Standards and Manual of Practice development.
