Stormwater Management Applications

  • Soil Stabilization

    Problem: Poor load-bearing soils pose a significant problem for transportation and construction needs. Unpaved areas, such as access roads, paths, parking lots, driveways, etc can be highly vulnerable to near-surface shear failure and rutting, especially in moist conditions or areas with higher expected loads. Typically, engineers bridge over weak soils with rigid structures such as thick, reinforced concrete for roads and highways. However, such techniques are prohibitively expensive and inordinately difficult to install. The poorer the quality of the sub-base and the heavier the expected loads, the greater the amount and better the quality of support required.

  • Dust monitoring and Sand Storm Monitoring

    The frequency and intensity of dust and sand storms in many parts of the world are steadily increasing due to droughts and climate change. The severity of such storms is anticipated to increase over the coming years. These dust storms may last hours or days and cause huge damage and imposed a heavy toll on society with its physical effects, such as visibility reduction, heavy winds, red sky, hailstone and severe lightning. Such Dust storms, have a negative impact on human health, and industrial products and activities. They reduce visibility, layer on skin and cloths, infiltrate buildings and find their way into food and drinking water leaving a permanent sandy feeling in your mouth. Traditional dust monitoring instruments whether they be purely filter based gravimetric samplers or continuous monitors utilising Tapered Element Oscillating Microbalance (TEOM) or Beta Attenuation (BAM) simply are unable to cope with the high dust loads created by these storms. The filters on these instruments are quickly clogged and no further measurements are possible until a service technician visits to replace filters and filter tapes. In dust storm events this is impossible. Therefore, over the past few years a need for alternate technology which are non filter based, can cope with extremely high dust loads, require minimal maintenance and can operate off solar power has been employed in regions such as the Gobi Desert of China for the continuous monitoring of dust storm events. These instruments have demonstrated that an instrument can measure dust storm events with maintenance performed only once every 12 months. That it is possible to communicate remotely and that these systems can not only provide an early warning for dust events but have the accuracy and sensitivity to be an extremely useful tool in gauging hourly changes of visibility. Infact such instruments have been utilised by a number of EPAs around the world, including all Australian EPAs for the purpose of measuring ambient visibility as well as providing an accurate indication of rising dust events.

  • OneRainware™ - Radar rainfall for real-time and analytical applications.

    Accurate estimation of the spatial distribution of rainfall is critical to successfully model hydrologic processes. OneRain has worked with engineering firms and those with responsibilities in Stormwater and Wastewater Management across the U.S. to provide radar rainfall data to help characterize storm events or flow problems in collection systems and as a basis for both real-time and design-oriented modeling. OneRainware products and services offer: *Real-time gauge-adjusted radar rainfall (GARR) data *Real-time area-average rainfall *Real-time forecast rainfall *End-of-month archive quality gauge-adjusted radar rainfall data *Historical and post-event analysis using archived rainfall estimates *Web-delivered calibrated radar-rainfall data *StormProperties™ Analysis. GARR data are used in flood warning, runoff modeling, basin modeling, I/I studies, litigation, real-time control, design storms, and National Pollutant Discharge Elimination System (NPDES) compliance activities.

  • Geosynthetic Lining for Highway and Civil Applications

    GCL can be used in highway and civil applications such as at airport de-icing facilities used to remove ice build up on the surfaces of planes. During the application process, glycol-based de-icing fluids can leak into local stormwater runoff, potentially causing pollution. CETCO GCLs were found compatible with de-icing fluid (glycol diluted 50/50 with water). GCLs can also be used to line roadway drainage swales for containment and prevent excessive percolation, thereby minimizing potential for groundwater contamination. Another example of using GCL in civil and highway applications is using the liner to contain acid rock and prevent runoff from entering the local water supply.

    Storm water flushing for sewage wastewater treatment

    With the increased use of storm water retention tanks, the need arises to routinely clean the tanks. Regular cleaning maintains combined sewer overflow (CSO) capacity and prevents septicity and odor problems associated with stagnant effluent. PWTech® Tipping Buckets provide a simple yet robust solution for flushing retention tanks.

  • Channel Wall Protection

    Problem: Channels are oftentimes subject to debilitating erosion due to the water contained by the channel walls. Depending on the velocity of the water flow and the frequency and degree of stormwater runoff, severe hydraulic stresses upon the channel walls can pose significant dangers to the system.
