01. Onsite sodium hypochlorite generation
De Nora said its onsite sodium hypochlorite generation is a cost-effective, reliable, and safe alternative disinfection treatment method, with consistent chlorine concentration and residual in the treated water. ClorTec systems can reduce a customer’s carbon footprint and salt consumption by as much as 20 percent, according to the company, and reduce the production of disinfection byproducts. ClorTec systems are engineered to meet any specified application, with units ranging in capacity from 6 pounds per day to more than 3,000 pounds per day. To meet varying application-specific conditions, the ClorTec units are available as component-based or skid-based packaged systems.
02. Vinyl caps for sheet pile walls
Crane Materials International (CMI) introduced its ArmorWare VersaCap for capping walls made from CMI vinyl, aluminum, and composite sheet piles. The new system can ship flat, reducing its shipping size and expense. The components’ 10-foot lengths are also easier to ship and handle than traditional 20-foot-long caps. By trimming the 12-inch-wide top with a handheld circular saw, the ArmorWare VersaCap system can fit most sizes of CMI ShoreGuard vinyl, AlumiGuard, and UltraComposite FRP sheet pile profiles. The new capping system is also compatible with many common sizes of ancillary wall components, including top wales, banding boards, wood cap façades, and backing boards.

03. Stormwater treatment system
StormTrap completed the verification program with the New Jersey Corporation for Advanced Technology (NJCAT) for the new design of its SiteSaver stormwater treatment system. Following verification, the New Jersey Department of Environmental Protection (NJDEP) certified SiteSaver as an approved Hydrodynamic Sedimentation Manufactured Treatment Device. SiteSaver achieved greater than 50 percent Total Suspended Solids (TSS) removal utilizing the sediment blend specified by the NJDEP HDS Protocol and qualified for online installation under scour testing. SiteSaver also completed an additional verification program with NJCAT utilizing an alternative sediment than what NJDEP stipulates in its test protocol.
04. Surveyor’s safety vest
Galeton expanded its line of illuminator Hi Vis Workwear to include the #13161 Illuminator Class 2, Reflective and Glow in Dark, Surveyor’s Safety Vest w/iPad Pockets. The cool mesh vest features two-tone reflective stripes and glow-in-the-dark stripes for additional visibility, even when there is no light source. Additional features include reflective piping around all exterior borders, interior pockets large enough for iPads or tablets, exterior pockets with grommets and hook-and-loop flap closures, mic tabs, and webbing reinforcement for longer wear. The vest meets ANSI Class 2, Type R certification.
05. Stormwater hydrodynamic separator
BaySaver Technologies, an Advanced Drainage Systems, Inc. company, launched the Barracuda S4 high-performance hydrodynamic separator that removes sediment and other debris from stormwater runoff. The Barracuda S4 is designed with patent pending internal “teeth” that mitigate turbulence in the storage chamber to prevent re-suspension of captured contaminants. The Barracuda S4 is designed to be used in a single-manhole configuration and offers multiple pipe configurations, flexible inlet/outlet positioning, quick installation, and easy inspection and maintenance, the company said.

06. Synthetic microfibers for concrete
GCP Applied Technologies Inc., formerly Grace Construction Products, announced that its line of synthetic microfiber products, previously sold under the names Grace Fibers, Grace Microfibers, Grace Microfiber FDS, and Gilco Fibers, will now be marketed under the new Sinta brand. The product line includes Sinta F (fibrillated), Sinta M (monofilament) and Sinta FDS (fluid delivery system) synthetic microfibers for concrete. GCP’s Sinta microfibers are used to minimize cracking due to rapid surface drying of plastic concrete. Sinta microfibers are used in applications such as slabs on grade, pavements, overlays, sloped walls, pools, shotcrete, stucco, tunnels, precast, and prestressed products.

07. Rolled Erosion Control Products specifications
The Erosion Control Technology Council (ECTC) recently updated the Rolled Erosion Control Products (RECPs) specification. This specification includes charts of product characteristics for temporary erosion control blankets and turf reinforcement mats. These charts are the result of consensus among leading manufacturers of RECPs and are designed to satisfy the needs of engineers, designers, and other end-users of these products. A copy of the charts is available at www.ectc.org/toolbox.

08. Urban Street Stormwater Guide
The National Association of City Transportation Officials’ (NACTO) Urban Street Stormwater Guide illustrates a vision of how cities can utilize streets to address resiliency and climate change. The guide outlines strategies to creating streets that serve as truly public spaces, while delivering social and economic value, protecting resources, and reconnecting natural ecological processes. Developed through a collaboration between city transportation, public works, and water departments, and with support of the Summit Foundation, the NACTO Urban Street Stormwater Guide provides cities with national best practices for sustainable stormwater management in the public right-of-way.
