TRASH CAPTURE DEVICES
Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater runoff from naturally soaking into the ground.
Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is likely discharged into the waterbodies we use for swimming, fishing and providing drinking water. Sediment and debris being carried in the stormwater can cloud water and make it impossible for aquatic plants and life to grow.
The Water Decontaminator Trash Capture Devices are the best available technology for treating stormwater at the source. Stormwater carrying trash and other pollutants enters through the catch basin grate and is funneled through a filter housing. This filter is designed to take out trash and large particles (5mm) at the catch basin. An optional fine micron screen can be added depending on the application. Treated water then flows out of the Water Decontaminator Trash Capture Device into the catch basin.
Larger units with multiple strainer cartridges can accommodate any load. In addition, specific treatment cartridges can be added to treat pollutants that are present at a site.
This unit suspends beneath the grate, stormwater is captured into a 17 gallon housing. The dirty water then flows through the strainer cartridge to remove large particles and debris.
Depends on housing used. 17 gallon capacity is our standard design.
Minimum general service requirements. Fall or early winter: (One Inspection) Inspect and clean pre-strainers and grate area. Spring or early summer: (One Inspection) Remove sediment in housing as required. Inspect filter/absorber cartridges and replace when necessary. Replace or repair any damaged or defective components. Owner shall provide for street sweeping and general roadway and parking lot cleaning and notify service provider of any additional service needs.
Housing: HDPE solid housing suitable for full height sediment containment and shall be nominal 15 gallons retention size. Smaller size capacity may be used on shallow catch basins. A perforated tube shall be incorporated within the housing to allow the filter/absorber cartridge to slip on for easy replacement. A locking screw-on-cap keeps cartridge in place during use. Use modified or shorter housing (with less storage, flow and filtration) where depth of catch basin is shallow or to suit basin. Support System: The housing supports, including fasteners, brackets and or adjustable chains and Quick-Link connectors and other support frame items shall be type 304 stainless steel. Shallow basins and non-standard catch basins shall have round or rectangular stainless steel or HDPE support items as required.
CURB INLET SCREENS
The curb inlet screen can be fastened to the side walls of the opening or be clamped directly to the safety bar. The screen is made out of HDPE or stainless steel.
Minimum general service requirements. Twice a year leaves and debris should be removed from screen. Owner shall provide for street sweeping and general roadway and parking lot cleaning and notify service provider of any additional service needs.
HDPE mesh screen.
HIGH FLOW CAPACITY DEVICES
The high capacity weir filter design allows for high flow and large capacity holdings. The stormwater enters on one side of the filter/strainer and can overflow if needed. Units are easy to install and service as shown below.
Depends on catch basin size.
Minimum general service requirements. Fall or early winter: (One Inspection) Inspect and clean pre-strainers and grate area. Spring or early summer: (One Inspection) Remove sediment in catch basin as required. Inspect filter and replace when necessary. Replace or repair any damaged or defective components. Owner shall provide for street sweeping and general roadway and parking lot cleaning and notify service provider of any additional service needs.
Type 304 stainless steel mesh housing is bolted directly to catch basin.
