Vandal-proof signage

The SignGuardian™ provides a fast, secure, attractive, safe, tamper resistant and waterproof means to hang signs and banners. It works on standard 2-inch chain-link fence and another model works on poles. The unit is easy to install: just slide the Sign-Guardian™ onto the fence and tighten the set screw. Once a sign is attached by the 1-Way R™ bolt, the exclusive Lock-On feature™ provides the security. A special removal bit is required to remove the bolt.

Stormwater chamber

A new StormTech® chamber from Advanced Drainage Systems Inc. (ADS) is now available for use in deep cover underground commercial and municipal stormwater management systems. The StormTech DC-780 is designed in accordance with the AASHTO LRFD Bridge Design Specifications for live and dead loads. It also meets the design requirements of ASTM F 2787 and the product requirements of ASTM F 2418 . ADS, the world's largest producer of corrugated highdensity polyethylene (HDPE) pipe, completed its acquisition of StormTech LLC in March 2010. The chamber is made using an injection molding process to ensure uniform wall thickness throughout the chamber. It features more than 46 cu ft of bare chamber storage capacity can be used in systems requiring up to 12 feet of cover.

Check valve

The CheckMate™ Inline Check Valve is ideal for backflow prevention and odor mitigation. In outfalls, stormwater, CSO and SSO applications, the Check-Mate's™ custom-engineered, all-rubber unibody design eliminates costly backflow from oceans, rivers and interceptors. The valve's unique elastomer fabric-reinforced design provides a proven record of maintenance-free performance, cost savings and results that no other inline check valve can match. The major advantage of the check valve is its extremely low headloss. The valve can open to a near full pipe diameter. This maximizes the flow capacity of the outfall, which is particularly beneficial in low-lying areas where limited driving head is available. The valves are readily available in 4" to 72" sizes.

Stormwater sampler

The I-CHEM collects a full one-liter sample of first flush stormwater within the first 30 minutes of a rain event in compliance with EPA sampling requirements. A floating ball valve seals off the sample collection port to prevent co-mingling with runoff water as well as volatile analyte loss. Water flows through the sampler's collection funnel directly into a Nalgene® sample bottle, so no sample transfer is necessary before transport to the lab. The I-CHEM can be securely mounted in a stormwater ditch, stream, or storm grate outfall.

Sewer force main inspection

Sahara® technology was originally developed for leak detection in pressurized water mains, and is now quickly becoming the industry standard for sewer force main inspections as well. It allows the line to remain in service and inspections to take place at any point in time. Utilities benefit from a live main inspection process as there is often no redundancy to their pressurized sewer lines and service shutdowns can be complicated and costly. It's able to consistently locate the smallest leaks in any pipe material and locate pockets of trapped gas where hydrogen sulphide gas can build up and deteriorate the inside of the pipe wall. In addition, the actual location of the sewer main can be accurately mapped in real time as the Sahara ® sensor travels through the pipe.

Sediment sampling

The manually-driven, end-filling SBS Sediment Sampler is perfect for discrete interval sediment sampling in rivers, lakes, wetlands, and estuaries. To obtain a sample, simply lower the sampler to the surface as a dual tube or drive the sampler down to the desired depth where sampling is to begin below the surface. Once sampling is complete, the sampler disassembles easily for fast access to the sample liners that can then be capped off for transport to the lab. The sampler can take continuous or discrete samples from the sediment surface to 400 feet in depth.
