The geotechnical needs of DOTs and other agencies responsible for roads and bridges are vast. Issues include: Culvert repair Soil stabilization Void filling Concrete slab lifting Sinkhole remediation Slope control Slough control in tunneling
Protecting concrete usually means shielding it from the elements of nature or from harsh manmade chemicals. But it’s not just concrete that needs such protection. Corrugated metal pipe, steel surfaces, material hoppers, rail cars and masonry all can come in contact with corrosive or abrasive materials or harsh conditions.
Excerpt from the Summer 2020 issue of I&I Magazine:
George Kurz knows inflow and infiltration, and he’s willing to help your utility, free of charge.
Kurz, P.E., DEE, is a consulting engineer with a specialty in I&I quantification and reduction. He has 29 years’ experience in municipal engineering focused on reducing overflows and designing rehabilitation projects to reduce I&I. He has performed contract work for JACOBS, ResourceTek, BWSC (Nashville, Tennessee) and JMT (Sparks, Maryland).
At the recent No-Dig conference in Chicago, he presented a paper: “Simple Tool for Operators to Quantify I&I, Detect Leaks & Measure Rehab Progress.” This paper was the most recent installment representing seven years of his personal research on measuring I&I in municipal systems and included measurements for every municipal NPDES permitted system (523) in the states of Tennessee and North Carolina.
Kurz says his study represents the first time I&I has been quantified for every municipal system in a state. Additionally, at the end of his presentation he offered to analyze a year’s worth of data for any municipal system in the U.S. and Canada — for free. Later, I caught up with Kurz to discuss his research.
