Camera/crawler unit

The Cobra V10 C310 camera from Cobra Technologies is a short pan, tilt and zoom camera and 6-inch crawler combination for relined 6-inch pipe. Used with the Cobra C601 crawler, the camera can operate in relined 6- through 24-inch pipes. The 18-inch-long camera/crawler unit provides a compact assembly to avoid protruding laterals.

The stainless steel camera features automatic iris, focus, zoom and Luxeon lighting modules capable of lighting 36-inch-diameter pipe. The lighting operates on the camera power supply, eliminating the need for light head controls. The rotate and pan are capable of 360-degree continuous rotation. High-traction carbide wheels are available. Wheels can be added using a single point connection allowing for quick change for pipe sizes through 24 inches. The unit can be installed on any multi-conductor system. The camera can be used with any of the Cobra crawlers and is available with a conventional 3-inch body for use on industry standard multi-conductor systems. 800/443-3761; www.cobratec.com

Manhole antenna
cover systems

Manhole antenna cover systems from ELAN Technologies are designed for communicating with underground utility infrastructure. The system simultaneously collects, monitors and controls data from multiple devices and sensors (flowmeter, ultrasonic level sensors, floats, pumps, rain gauges), providing real-time detection of faults in electric vaults. The SCADA IN-A-BOX extreme low power RTU (remote terminal unit) measures six analog signals and 16 discrete inputs. Alarm management and data logging report all live conditions and historical data to SCADA, cellphones and data management systems using FTP, SMS and standard SCADA protocols. 815/463-8105; www.elantechnologies.net

Passive subsurface irrigation

The Environmental Passive Integrated Chamber (EPIC) from Firestone Specialty Products is an onsite water management and reuse system that enables stormwater runoff from impervious surfaces to be collected, filtered, retained and distributed below ground at the water's source. The system brings together passive subsurface irrigation, water storage and filtration in a single, customizable solution. It uses capillary rise and gravity to provide controlled water management.

The technology can decrease or potentially eliminate a facility's reliance on municipal water for irrigation purposes and improve best management practices (BMPs) with minimal system maintenance and management. The system uses local sand and gravel to filter and delay stormwater runoff prior to its entrance into city storm sewers or downstream bodies of water. 800/428-4442; www.firestonesp.com

Pipe leaching system

The GEO-flow HDPE pipe leaching system from Advanced Drainage Systems (ADS) is designed for use wherever a conventional septic tank and pipe and gravel leachfield system may be used. Easily transported and able to be installed in difficult areas, the system combines a 10-inch-diameter, single-wall high-density polyethylene (HDPE) corrugated pipe, surrounded in a polypropylene grid, both encased in geotextile fabric. The design creates equal distribution and enhances biological reduction of wastewater before it leaves the gravelless pipe system.

The equal distribution cools the effluent as it passes through, aids in the separation of foods, oils and greases from wastewater and provides additional treatment of solids that may escape the septic tank. The symmetrical grid separates the geotextile wrapping from the pipe, increasing the total surface area of the fabric available for biomat formation. The wrapping creates an additional layer for biomat activity, while using capillary action to wick effluent into the surrounding soil. 800/821-6710; www.ads-pipe.com

Backup system

The ReliaPrime emergency bypass station from Gorman-Rupp Co. operates on natural gas, making it quiet and environmentally friendly. The unit features a 6-inch Super T Series pump capable of passing 3-inch spherical solids and offers a soundproof, lightweight aluminum enclosure. The enclosure has padlocked door panels and can be removed for maintenance. The unit is a complete backup package, ready for hookup. 419/755-1011; www.grpumps.com

Portable flowmeter

The OPTISONIC 6400 portable ultrasonic flowmeter for liquids from KROHNE measures flow velocity, current volumetric flow and a variety of diagnostic values. The flowmeter consists of a compact evaluation unit and one or two rails, each equipped with two ultrasonic sensors. Rails are available in a variety of sizes to accommodate different tube diameters, from 1/2 to 160 inches. The flowmeter is powered by an integrated battery with 14 hours running time or line-powered with supplied adapter. Readings are displayed on a color graphic LCD screen. 800/356-9464; www.us.krohne.com

Double clarification

The BIOACTIFLO system from Kruger USA combines contact stabilization and microsand ballasted clarification to produce high-quality treatment of wet-weather flows. Return activated sludge (RAS) from the existing clarifiers is combined with the excess flows into a solids contact tank. A targeted mixed liquor suspended solids (MLSS) concentration is maintained in the contact tank to facilitate rapid uptake of soluble biological oxygen demand (BOD) via contact stabilization followed by ACTIFLO clarification.

The combination of the two results in total BOD removal in excess of 85 percent, greater than 95 percent TSS removal and total phosphorus levels of less than 0.15 mg/L. Existing ACTIFLO installation for wet-weather flows can be converted to BIOACTIFLO and the ACTIFLO train can also be used for tertiary treatment during dry-weather flows. 919/677-8310; www.krugerusa.com

Matchbox-size
data logger

The matchbox-size HOBO UX90 motor on/off data logger from Onset Computer has an LCD-display for monitoring the run times of motors, pumps, compressors and other equipment. The logger records up to 340,000 equipment on/off cycle changes and uses analysis software
(runs on PC or Mac) to convert recorded data into time- and date-stamped graphs. The logger attaches to motor housings via built-in magnets and without wiring. The display confirms operation, while a signal strength indicator ensures proper placement. 800/564-4377; www.onsetcomp.com

Line stop plugging systems

Multi-Flex line stop plugging systems from Petersen Products are designed for insertion through a small hot tap into a larger pressurized pipeline. The 128 Series installs a plug downstream of the tap, allowing bypass through the hot tap or nozzle insertion point, enabling flow to continue and reduce the buildup of head pressure. The 129 Series installs directly below the hot tap or nozzle and can be made for much higher pressure than the 128 Series. Custom configurations are available. 800/926-1926; www.pipeplug.com

Level transmitter

The PMC VersaLine model VL4500 level transmitter from Process Measurement & Controls features ±0.1 percent accuracy and molded cable. Made for long-term submersion in wells or runoff pipes, the unit provides reliable monitoring of surface water. The titanium-housed unit is available in various electrical configurations including 4-20 mA, 0-5 VDC, RS485 or SDI-12. The transmitters operate on the hydrostatic pressure principle, and by selecting products with the correct construction and taking the appropriate installation precautions, they can provide years of maintenance-free service.

Data logger and wireless communications models are also available. No breather tube is required. The key to long-term success is the installation and more specifically the breather termination. No breather is required with the added expense of a surface-mounted barometric sensor. For the more common and accurate transmitters incorporating the breather, there are a number of methods to provide up to 12 months protection, such as desiccant. The PMC MP11 bladder is also available for zero maintenance. 800/869-5747; www.pmc1.com
