AP/M PERMAFORM
AP/M’s new process for the structural renewal of culverts and sanitary sewer pipe—without backhoes, repaving, traffic detours, flooding, or hazardous construction—is called Centri-pipe, short for centrifugally cast concrete pipe. Corrugated metal, with its propensity to rust and buckle, has a designed life of 20 to 30 years. Replacement options include digging and its unavoidable disruption, sliplining with its reduced capacity, or expensive cured-in-place liners. Without digging, liners, or reduction of capacity, and at significant savings, Centri-pipe creates a new, structurally sound concrete pipe inside the old one. The pipe is environmentally sound, waterproof, and fully sealed from end to end and provides highly effective corrosion protection that can double the life of the pipe.

BRENTWOOD INDUSTRIES
Brentwood’s new StormTank Stormwater Storage Modules are a high-void, strong, affordable alternative to crushed stone, concrete structures, or pipe chambers for subsurface stormwater detention or infiltration basins. They offer the largest void space of any underground stormwater storage units currently on the market (97%), and are load-rated for use under parking lots, athletic fields, parks, etc. The entire StormTank Storage System is built onsite from 18-inch-wide x 36-inch-long Top/Bottom Panels and Side Panels made of rugged, lightweight polypropylene and 2-inch to three-eighths-inch-diameter PVC columns (18-inch to 36-inch lengths). Combinations of these three components create all the module configurations needed for a fully functioning underground system.

CONTECH
The CatchBasin StormFilter from CONTECH is a low-cost, low-drop, point-of-entry stormwater treatment system. Offering small-scale, decentralized treatment using the proven Stormwater Management StormFilter technology for the removal of fine sediment, nutrients, metals, and bacteria, it is easily incorporated into low-impact development (LID) site designs. The three-in-one design combines a catch basin, a high-flow bypass device, and a StormFilter cartridge into one structure, which reduces capital and installation costs and simplifies the overall site design by eliminating two structures.

DRIPS LLC
The Big Bags USA system is the fastest deployed flood barrier. The system has proven to be a very effective coffer dam tool. Garney Construction, based in Littleton, CO, used it for a rock retaining wall job. The systems can be filled then lowered into place with a crane or large backhoe. Once the barrier is built, you pump out the water and go to work.

GATOR GUARD ENVIRONMENTAL PRODUCTS INC.
In today’s market, contractors need tough, lasting, effective, economical BMPs. Gator Guard wattles have five years of life expectancy, 20 times less soil loss than straw wattles, and real cost savings—even for single use. They survive tires, tracks, wind, water, and sun on several projects. Made from UV-resistant geotextile and stuffed with recycled foam, a 25-foot wattle weighs only eight pounds, including nails provided. New, larger foam pieces minimize litter from major rips. Ponding action captures more silt and clay, lowering NTUs.

GREYLINE INSTRUMENTS INC.
Greyline Instruments Inc.’s new flowmeter monitors flow through open channels, partially full sewer pipes, and surcharged pipes without a flume or weir. It is designed for municipal stormwater, combined effluent, raw sewage, and irrigation water. The new Greyline AVFM 5.0 uses a submerged ultrasonic sensor to continuously measure both velocity and level in the channel. The sensor is resistant to fouling and corrosion. The AVFM 5.0 can be configured with the standard submerged velocity/level sensor, or with submerged velocity and a separate non-contacting ultrasonic level sensor. It includes a backlit flow rate display, totalizer, three 4-20 mA outputs, and two control relays.

J. W. FAIRCLOTH & SON INC.
Faircloth Skimmer surface drains float on the surface of the sediment basin as it fills and drains, releasing the cleanest water from the surface instead of draining muddy water from the bottom as conventional outlets do. The skimmer drains the basin slowly over several days at a constant rate to maximize settling. The adjustable orifice regulates the filling and drawdown of the basin and improves efficiency.

NATIONAL ASPHALT PAVEMENT ASSOCIATION
Porous asphalt pavements allow for land development plans that are thoughtful, harmonious with natural processes, and sustainable. They conserve water, reduce runoff, promote infiltration, which cleanses stormwater, replenish aquifers, and protect streams. A typical porous pavement has an open-graded surface over an underlying stone recharge bed. Rainwater or snowmelt drains through the porous asphalt and into the stone bed, then slowly infiltrates into the soil. At that point, Mother Nature does a great job of cleansing the water. Porous asphalt can be a great contributor for stormwater management.

PINE HALL BRICK CO. INC.
When laid in a permeable pavement system, Pine Hall Brick Company Inc.’s StormPave permeable clay pavers allow rainwater to filter through and dissipate into the soil rather than carry excess pollutants into storm drains and waterways. StormPave can help qualify in up to five LEED categories. Pine Hall, in operation since 1922, specializes in pavers. The company has two state-of-the-art manufacturing plants dedicated to pavers and is the largest supplier of genuine clay pavers in the US.
