Case Study: New Orleans Addresses Storm Water System Vulnerabilities
Customer As a result of its unusual topography, the city of New Orleans is prone to flooding from the Mississippi River and Lake Pontchartrain, as well as frequent inundation from high intensity rainfall. Since the late 1800s, New Orleans Sewerage and Water Board (NOSWB) has been tasked with providing the city adequate drainage, sewerage collection…
Read MoreCase Study:Texas Municipality Diverts Flow in Large Diameter Sewer Lines
By: Brandon Dalton Customer In the past few years, there have been several sewer line rehabilitation projects in Texas involving large diameter sewers (6 feet to 11 feet diameter) located 50 feet to 60 feet below ground. These projects have either required the city to block flows in order to divert to other sewer lines…
Read MoreEngineered Composite Stop Logs
Stop logs are in commonly used in water and wastewater treatment plants, lagoon control, flood control, and flow diversion. Historically, most stop logs are constructed of wood or metal. However, vacuum infused Fiberglass Reinforced Polyester (FRP) design is proving to be a much better solution for stop log design. Wood swells as it takes on…
Read MoreA Solution for Excessive Approach Velocity in Flumes – The Energy Absorbing Manhole
Excessive approach velocity caused by pump flow or steep pipe slopes can be an issue in some flume applications. One of the tools we have to solve this problem is the Plasti-Fab Energy Absorbing Manhole Brochure. The manhole features an energy absorbing plate that is slightly larger than the incoming line. The water hits this…
Read MorePlasti-Fab Engineered Composite Flow Control Gates . . . . . There Is a Difference!
Article courtesy of Mike Keegan with Plasti-Fab, Inc. Referring to a Plasti-Fab gate or stop log as FIBERGLASS is like stating a Porsche Carrera GT is just a CAR. They both might fit the basic definition, but that is where the similarities end! Conventional fiberglass molding and fabrication techniques (spray-up or chopper gun processing) are…
Read MoreJapan’s Public Works Research Institute’s Findings on FRP Gate Evaluation
Japan’s Public Works Research Institute performed an evaluation of 53 fiberglass reinforced plastic hydraulic gates that have been in use for over 30 years with little maintenance. Their evaluation included visual inspection of in-service FRP gates, tensile tests on one FRP gate in use for 35 years, and accelerated weather weathering tests on hand lay…
Read MoreFRP / Engineered Composite Gates vs. Traditional Metal Gates
The overall benefits of a Fiberglass Reinforced Plastic (FRP) product compared to aluminum, coated aluminum and steel products, go far beyond what is immediately evident when reviewing technical data sheets and test results. Depending on the environment and severity of product exposure, the practical requirements and suggestions for use along with comparative data collected from…
