Stormwater management

Click here to enlarge image

GEOtivity’s goal is to provide urban centers with proactive stormwater management tools that allow preventative action to be taken before the storm has even arrived. To this end, the company has developed its Virtual Rain Gauges. The gauges combine live weather surveillance radar data with site rain gauges to produce predictions of storm events. Alarms can be created based on these virtual rain gauges to warn of impending storms. Sewer flow can then be diverted to other routes, thereby preventing overflows.

Advanced Drainage Systems (ADS) has purchased two additional Cincinnati Milacron injection molding machines and additional tooling to support its growing sanitary leaching chamber business. These 2,300 ton injection molding machines will be used to make the company’s ARC™ leaching chambers. The chambers are made from high-density polyethylene (HDPE) and have an open bottom and curved top that produces increased load-bearing capability in the trench. Leaching chambers are increasingly replacing the traditional gravel and pipe set-up in septic leach field applications because they are easier to handle, and have lower labor and materials costs. One of the additional Milacron units will be installed at ADS’ dedicated injection molding facility in Winchester, KY. The other machine will be placed in one of the company’s plants in the Pacific Northwest to support the growing customer base on the west coast. Both are expected to be on-line later this year.

Vortex separator

Click here to enlarge image

The Grit King energy-free vortex separator from Hydro International operates on the principle of dynamic separation. Flow is introduced tangentially, generating rotary flow. Flow spirals around and down the perimeter, then inward and upward in a continuing spiraling motion. A single centrally located discharge at the top of the vessel forces fluid to follow a long path before it is released, providing sufficient time for even finer grit to settle. A centrally directed sweeping action concentrates settleable material in a central location. Patented flow-modifying internal components are used to stabilize and enhance the effects of rotary and shear forces, reducing turbulence and maximizing performance over a wide range of flow rates.

Backup pumping system

Click here to enlarge image

Due to the environmental impact of CSOs and SSOs, lift station pumping must be reliable and continuous - including the ability to respond to varying flow demands regardless of time of day or availability of electricity. Godwin’s Dri-Prime Backup System (DBS) provides independently powered pumping in one convenient package for emergencies including primary power, switch gear and sewage pump failure or repair; and primary pumping during routine maintenance. With available flows to 10,000 gpm and heads to 600 feet, the system provides simplicity through a stand-alone automatic self-priming pumpset independent of utility line power and lift station pump control. A pressure transducer or float switches provide start and stop controls that activate the diesel- or natural gas-driven pump when the water level rises to a predetermined height. Godwin’s automatic priming feature removes air from the suction line, creating a vacuum that allows water to rise and the pump to establish prime. The pumpset continues to pump the required flow and shuts off when either the wet well is lowered or the electricity is restored, and the primary system retakes control.

Stormwater filtration

BaySaver Technologies has launched its new BayFilter stormwater filtration system. The new multilayered underground sand filtration system removes very fine sediment and nutrient pollutants from stormwater runoff at a flow rate of 30 gpm per cartridge. As stormwater makes its way through 43 square feet of surface area per cartridge, the filter removes more than 80% TSS (d50 = 23.2 microns) and greater than 50% of total phosphorous including dissolved phosphorus. It also boasts a 50% reduction of turbidity. The filter’s unique hydrodynamic backwash self-cleansing component dislodges pollutants and restores the porosity of the media after every storm, contributing to efficient operation and extended maintenance intervals. The filter system can be customized to help specifying engineers, regulators, developers and contractors with regulatory compliance, limited space conditions, and installations in ecologically sensitive areas.
