This was an email from John Carney of Trenchless Technologies, Inc: The collaborative presentation by us, who will actively participate in the presentation are myself, with Trenchless Technologies, Inc. and No- DigTec, LLC and John Newell, Managing Partner of No- DigTec. and Mark Mathis, who is the former WL Prospecting, Owner /President of WL Prospecting, specializing in Conducting Standard AWWA Water Audits for Texas Utilities, and a former member of the Texas Water Development Board — December 2003- August 2011 who Authored the Water Audit Reporting Worksheet and two water loss manuals entitled, "Texas Water Loss Manual for Texas Utilities. Mark is also a Current Member of AWWA Water Loss Control Committee John Newell is the pipe bursting specialist. No- DigTec, LLC is a nationally recognized, award winning Trenchless Pipe bursting company technology is a well - established state of art utility replacement process for the installation, replacement or renewal of underground utilities. It is very impressive that Paris is taking a bold initiative to address failing infrastructure, but we don't think you're doing it using the best technology, materials and not properly prioritizing your water main replacement using the latest in leak detection technology. Pipe bursting is one form of Trenchless Technology, and it is superior to open trench excavation in several respects, including significantly less disruption of businesses along the route of pipe replacement. Instead of digging two trenches in the street, which have to be 10 ft apart will significantly disrupt commerce and traffic, whereas trenchless pipe bursting will have a small entry hole dug every 700 ft or so. My rough estimate of the dirt to be displaced using trenchless pipe bursting is 3% of that displaced by open cut. The result is much less disruption of traffic, commerce and life in Paris. HDPE pipe, the preferred pipe for both sewer and water is monolithic when installed. For instance my rough calculation is that using PVC for the Paris Capital Improvement Plan there will be upwards of 22,000 mechanical joints, connections which are future potential points of leaks, where the HDPE pipe, fused at the joints, taps and connections will have only 348 mechanical joints. The HDPE pipe has twice the life expectancy of PVC, and 100 year life is expected. Another major factor is the environmental impact of the project on the community, with trenchless having 85% less pollution in the community. We will also discuss how to select and prioritize water main replacement. Your Capital Improvement Plan is only replacing 8% or so of the existing utilities and selection of the pipe for replacement giving the biggest financial impact, produces savings that can help fund future water main replacement. Paris' own reporting to the Texas Water Development Board show that you only know where 2 tenths of I% of the water loss from leaks comes from. Without using the state of the art leak "survey" technology you are relying on historical repair data, which identifies only a very small part of the leaks actually occur.
