Prepackaged pump system
Flo-Pak Municipal-Pac prepackaged pump systems are engineered for handling clean water applications including potable water boosters, raw water intakes, and tank fills, in both underground capsules and aboveground units. System designs accommodate flows from 100 gpm to more than 14,000 gpm and pressures up to 300 psi. Patterson Pump Co.

Repair concrete, asphalt, wood, or steel
FlexKrete becomes three times harder than standard concrete in an hour or less. The concrete repair product resists damage from road salt and freeze/thaw cycles, and can withstand high-speed car and heavy truck traffic. The nontoxic, virtually odorless resin can be used to repair concrete and asphalt - including curbs and potholes - wood and steel on horizontal, vertical, and overhead surfaces. Whether used in deep holes or feather-edged, it attains more than 10,000 psi. It can also cure at 0° F. FlexKrete Technologies, a div. of Protective Products Inc.

Portable time and attendance system
Designed for construction sites, the TimePilot Extreme is a portable and weatherproof time and attendance system. Workers can clock in and out onsite, and when the project is finished, the clock can be removed easily and taken to the next site. Workers are given a key-sized device, called an iButton, to clock in and out by tapping the clock. The waterproof iButton can be carried on a keychain, can be reassigned to another employee, and lasts at least 10 years. TimePilot Corp.

Packaged MBR systems
Using Puron submerged membrane technology, the preassembled membrane bioreactor systems integrate membrane filtration and bioreactor processes for wastewater treatment plants with up to 200,000 gal./day capacities. The systems are designed for denitrification, advanced tertiary polishing, and scalping applications. Each module uses a single header with hollow fibers that are fixed only at the bottom; the sealed upper ends float freely. This eliminates buildup of hair and other materials. Koch Membrane Systems.

Hatch railing system for roof doors
The BIL-Guard is a fixed railing system that provides a permanent means of fall protection for hatch openings. Constructed of durable fiber-reinforced polymer material and corrosion-resistant hardware, and featuring a high-visibility yellow color for safety, it mounts directly to the capflashing of any roof hatch. It is designed to satisfy OSHA standard CFR 1910.23, which requires the exposed sides of roof openings to have guardrail protection. The Bilco Co.

Remote-mount flow meter
The ST50 Remote Mount Flow Meter consists of a remote-mount air/gas flow sensor and a transmitter designed to perform in confined spaces or hazardous areas where flammable or toxic gases may be present. The transmitter may be mounted up to 50 ft. away from its thermal mass flow sensor and operates at temperatures from 40° to 100° F. It is also available with built-in wireless infrared communication technology and may be used with a standard Palm OS PDA. It also features dual analog outputs, which are field-assignable as flow rate or temperature. Fluid Components International.

Stormwater retention system
The cost-efficient ChamberMaxx system - a corrugated, open-bottom plastic arch system to retain stormwater runoff - stores up to 49 cu. ft. of water per chamber. With a short height profile, the system installs belowgrade to maximize available land for development. The chambers are injection-molded with polypropylene resin and are designed to exceed HS-20/HS-25 live loads in accordance with AASHTO specifications for stormwater chambers, so they can be installed under parking lots and roads. They are also lightweight and do not require heavy equipment for installation. Contech Construction Products Inc.

Sewer bypass pump
The HH225c 8-in. pump produces large flows and high discharge heads for applications including sewer bypass and temporary fire protection systems. The pump handles solids up to 3 3/8 in. and produces flows up to 5,400 gal./minute and discharges heads up to 405 ft. The engine and pump are mounted on galvanized skids to protect against rust and corrosion. Rain for Rent.

ADA-compliant stabilized gravel
Both porous and compliant with the Americans With Disabilities Act, Gravelpave2 is made of recycled geotextile fabric attached to a 1-inch-high integrated ring and grid system. It is designed to stabilize loose aggregate. Gravelpave2 sits atop an engineered porous base and is filled with gravel. Typically the product is installed in parking lots, access roads, and trails. Invisible Structures Inc.

Drain cleaning machine
The Electric Eel Model D-5 drain and sewer cleaner is a continuous cable drum machine used for cleaning 3-in. to 10-in. diameter lines up to 100 ft. Powered by a ½-hp capacitor-type motor, it runs a ¾-in.-diameter Tri-Max cable. Three sealed, heavy-duty ball bearings support the drum, and a thick-wall guide tube extends wear. The high-density polyethylene drum and belt guard will not rust or dent. The power feed and drum can be quickly removed, with the loading wheel built into the handle. Electric Eel Mfg. Co. Inc.
