Stormwater Management

Click here to enlarge imageSubsurface water storageInvisible Structures has introduced Rainstore3, a new class of subsurface water storage created to fill a storage niche between structural tanks and reservoirs and buried pipe and arch systems. The system features thin-walled cylindrical columns of injection molded resins made from recycled high impact polypropylene (HIPP), or high density polyethylene (HDPE) plastics. The storage system can be as shallow as 4 in. or as deep as 98 in. Length and width in 40 in. increments allow for modular design flexibility. Other advantages include the system's design, which places the plastic entirely in compression rather than bending or tension, resulting in H-25 loading, and a void storage volume of 94%.Invisible Structures, Inc.Aurora, COTel: 800-233-1510Web: www.invisiblestructures.com

It permanently separates oil from water and allows virtually no oil emulsion formations to develop. Independent testing demonstrates that the system's separation efficiency for free oils and hydrocarbon-laden sediment exceeds environmental standards. The units are designed for use in point-source and industrial stormwater applications. No external energy supply is needed. An automatic shutoff valve provides protection against unexpected spills or maintenance neglect when maximum oil storage capacity is reached or when a certain liquid level is exceeded.Royal Environmental Syst., Inc.Stacy, MNTel: 800-817-3240Web: www.royalenterprises.net

The SSO-31 is designed for non-critical points and for planning purposes. Data is transferred to Telog's Palm Pilot based on a data transfer unit or to a laptop running Telog for Windows software. The recorder is hung near the top of the manhole so there is no confined entry necessary for data collection. The SSO-33 is designed for critical points of monitoring. It provides the added benefits of wireless communication and multiple parameter monitoring.Telog InstrumentsVictor, NYTel: 716-742-3000Web: www.telog.com

It is designed to retain suspended and floating solids, keeping the discharge water free of recognizable solids. The screenings are diverted to a wastewater treatment plant or to collection. The screens are self-activating and self cleaning. They are mounted on the weir, and thus become an emergency overflow weir.Parkson Corp.Fort Lauderdale, FLTel: 305-974-6610

The company's first flush system directs a pre-determined amount at the beginning of a rain event to treatment, and then allows the remaining rain to flow to the storm drain. The company also offers a spill control system that detects a spill, diverts it to the proper treatment or holding area, and then alerts a designated person.Wastewater Diversion Syst., Inc.Mechanicsville, VATel: 804-730-1280

Click here to enlarge imageStormwater controlBaySaver® Separation Systems remove oils, suspended solids and floating debris from stormwater runoff. Driven entirely by gravity, stormwater flow enters a primary manhole for initial separation. The light fractions are then treated a second time in an off-line storage manhole, where fine suspended solids and floatables are collected. Stormwater flow is regulated into the secondary manhole so the pollutant materials can not be re-suspended by higher flows. Installation of the system can be completed with normal construction equipment (no cranes) in a single day.BaySaver, Inc.Mount Airy, MDTel: 800-229-7283Web: www.BaySaver.com

Click here to enlarge imageStormwater by-passCSR offers the Inlet Stormceptor for removing a high percentage of sediment, oil and other pollutants from storm water run-off. The device is only 48 in. in diameter and replaces a traditional inlet structure. Because it incorporates an internal by-pass, the design allows high-flow events to by-pass the unit and prevents scouring of previously trapped pollutants. A fiberglass insert extends into the lower chamber to provide added protection against volatile hydrocarbons.CSR StormceptorKansas City, MOTel: 800-909-7763Fax: 816-741-2167Stormwater filtrationMycelx Technologies has introduced a stormwater filtration system that fits in parking lot drain units and works to remove harmful pollutants found in runoff. The filtration system can also be used in plant floors. It uses a gutter system in conjunction with a water filtration unit filled with SilaKleen media (an expanded silicate) to catch the "first flush" of rainwater which contains the highest concentration of oil and gas contamination.Mycelx TechnologiesGainesville, GATel: 888-306-6843Web: www.mycelx.com
