The thermoplastic powder coating is certified for use in drinking water system components
Axalta Coating Systems, a supplier of liquid and powder coatings, received certification in accordance with NSF/ANSI Standard 61: Drinking Water System Components – Health Effects for its Abcite thermoplastic powder coatings, which are used in a variety of industrial applications, including pipe and fittings for drinking water systems.
AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
Acquisition meets demand for expedited plastic pipe performance and custom R&D testing
NSF Intl. acquired the laboratory portion of Jana Laboratories Inc., an engineering consulting and laboratory testing firm that serves the global water and plastic pipe industries. Jana Laboratories’ 14-person laboratory staff and 20,000-sq-ft laboratory in Aurora, Ontario, Canada will be renamed NSF Janalab and become part of NSF’s global network of ISO/IEC 17025-accredited laboratories throughout North and South America, Europe and Asia.
Utah State University study validates the performance of PVC pipe used in water networks
The Utah State University (USU) Buried Structures Laboratory has published a comprehensive study on PVC pipe excavations, testing and lifecycle analysis. USU, located in Logan, Utah, is also home to the Utah Water Research Laboratory and has contributed to water and wastewater research internationally for more than 50 years.
NSF Intl. issues WaterMark Certification to Simon Co. for its HIM Safe polyethylene pipe and fittings
NSF Intl. has certified Simon Co.’s HIM Safe polyethylene (PE) pipe and fittings to the Australian WaterMark Certification Scheme for plumbing, water treatment and distribution products. Simon Co.’s products are the first PE pipe and fitting products to earn WaterMark certification from NSF Intl., and Simon Co. can now use the WaterMark logo on approved products and distribute to the Australian, Malaysian and New Zealand markets.
When choosing pipe or fittings for any water application, the material options can be overwhelming. This was not always the case, though: For centuries, most pipe was made of lead or wood. In fact, the word plumbing is derived from the Latin word for lead, plumbum. Although the mechanical properties of lead are advantageous for making pipe, its toxicity is an issue. Wood pipe, on the other hand, is nontoxic, but susceptible to leaks. And because wood is soft, people could easily drill into the pipe and steal water.
Evaluating the strengths and weaknesses of plastic pipe varieties
Recently I learned that fire hydrants use a color-coding system to indicate the flow rate a hydrant can deliver. Hydrants with light blue-coated bonnets and nozzles deliver the fastest flow rates, 1,500 gal per minute (gpm) or greater, while hydrants with red-coated bonnets and nozzles deliver 499 gpm or less. Coatings are amazing products—not only are they aesthetically pleasing, they also provide surface protection or improvement and can convey important information to the end user.
Limit coating toxicity with proper application
Recently, the U.S. Environmental Protection Agency (EPA) announced it had worked with three New Jersey school districts to successfully lower lead levels in their drinking water. Testing in 2010 and 2011 found elevated lead levels in approximately 8% of the outlets it tested at the Atlantic City, Union City and Weehawken school districts. The districts resolved the problem through a variety of methods, from filtration to replacing fixtures to simply shutting off those outlets. The latest round of testing showed that lead levels were within acceptable EPA limits.
In July 2011, the California Department of Toxic Substance Control (DTSC) issued its first annual report on plumbing products sampled and tested for lead concentrations in 2010. All drinking water faucets that were sampled and tested were reported to comply with the state’s new low-lead law.
