Geosynthetic available in wider rolls
Strata Systems, Inc., announced that its StrataGrid line of geosynthetic products is now offered in 18-foot widths. Measuring 18 feet wide by 600 feet long, each StrataGrid panel covers 1,200 square yards. Compared with geogrids in standard 12-, 6-, and 4-foot widths, StrataGrid’s wider coverage translates into fewer rolls that installers must handle per job and fewer seams to splice between adjacent panels. StrataGrid is manufactured from high-tenacity, knitted polyester yarns in an array of grid apertures, strengths, and designs. According to the company, it provides superior grade separation performance in segmental retaining wall and slope soil reinforcement applications.

Wireless option for pipe-inspection camera
Envirosight LLC’s QuickView pipeline zoom camera can now transmit real-time inspection footage wirelessly to any truck-mounted video monitor or recorder. A new wireless option allows remote viewing during inspection, multiple viewers, and collection of easement inspection video directly into data collection software. The wireless equipment comprises a compact transmitter that is part of the QuickView operator vest and a receiver that connects to a remote viewing or recording device. Video can be transmitted as far as 1,000 feet line-of-sight (300 feet otherwise) using one of eight, user-selectable channels in the 5.725-5.875 GHz range. According to the company, wireless functionality adds only minimal weight and power consumption to the system. The wireless option is available for all new and existing QuickView systems.

Rejuvenate failing septic systems
Aquaworx, a division of Infiltrator Systems, Inc., offers the Remediator system to rejuvenate failing wastewater drainfields by enhancing the natural treatment process in which oxygen and bacteria work together to maintain a clog-free septic system. Under normal operation, a septic system builds up a biological layer (biomat) that restricts the soil’s ability to absorb water. Over time, the biomat may become overly restrictive ultimately causing a system malfunction. The Remediator uses a fine-bubble air diffuser to introduce oxygen into the bacterial growth media column so the bacteria can begin to thrive and consume organic matter. According to the company, the aerobic bacteria combine with the oxygen-rich effluent in the tank and then move to the drainfield to reduce the clogging layer and restore infiltration into the soil.

Wastewater collection system monitoring
ADS LLC says it ADS FlowAlert depth-based alarm system offers an economical alternative for wastewater collection system monitoring. The wireless alarming system supports both float switches and a depth sensor and can be deployed as a stand-alone unit or as part of a comprehensive flow-monitoring network. FlowAlert uses two float switches to provide date- and time-stamped depth notification. An optional depth sensor logs depth readings for use in depth trending and flow calculation. The wireless communication platform instantly notifies as many as three text or e-mail addresses of unusual flow conditions—low, high, and critical high depth. The unit is housed in a submersible enclosure. According to the company, FlowAlert can be installed without confined space entry and requires no external power, cabling, or other infrastructure.
