Inlet Filters | Catch Basin Inserts Operation and Maintenance Manual 03 Curb Inlet Basket™ Information Standard Capacity Curb Inlet Basket™ and High Capacity Curb Inlet Basket™ Information The Standard Capacity Curb Inlet Basket™ (used in shallow catch basins) and High Capacity Curb Inlet Basket™ (used in deep catch basins) are specialized inlet filters used specifically for curb inlets where the only access element is a manhole. Both units are made of UV Coated marine grade fiberglass and stainless steel to ensure longevity and durability. Stormwater flow is directed into the filtration basket via a shelf system that is located directly under the manhole for easy access. Under high volume flows, the water can bypass the filtration system by simply flowing past the filter and into the catch basin. Benefits • Will not impede design flow of the inlet. • Removes more than 80% of total suspended solids. • The High Capacity Curb Inlet Basket is able to retain hundreds of pounds of debris and sediment. • Screens of different sieve sizes optimize filtration and flow. • Bypass openings prevent clogging. • Multi stage filtration captures hydrocarbons, sediment, litter and foliage. • No need to enter the confined space of the catch basin. • Easily serviced by vacuum truck. Inlet Filters | Catch Basin Inserts Operation and Maintenance Manual 04 High Capacity Curb Inlet Basket™ with built in shelf system for ease of installation and service. For use in deep catch basins. Standard Capacity Curb Inlet Basket™ with built in shelf system for ease of installation and service. Typically used regularly in shallow catch basins. Curb inlet where servicing can only occur via access from the manhole. Curb Inlet Basket™ Operation Operation Summary The Curb Inlet Basket™ (CIB™) and High Capacity Curb Inlet Basket™ (HCCIB™) are unique for their “Shelf System” which directs stormwater flow into the filter positioned directly under the access manhole. The Shelf System can be manufactured to any size and style of catch basin. The CIB™ and HCCIB™ are multi stage filtration systems that can capture a variety of pollutants during a storm: 1 Stormwater carrying debris and pollutants enters the inlet through the curb. 2 An adjustable throat width funnels water to the weir. The immediate drop in the throat elevation prevents head loss through the inlet. This allows sediment to collect along the incoming side of the weir. 3 The water then flows over the weir and into the removable filtration basket, filtering out trash, foliage and sediment. Furthermore, If a StormBoom™ is installed, it will filter out any hydrocarbons from the stormwater as it flows into the filtration basket. 4 Filtered water leaves the basket and enters the catch basin where it flows down stream. The position of the curb inlet basket high in the catch basin allows for captured debris to dry between storm events as well as avoid restriction to any up stream pipes.

Curb Inlet Basket™ Maintenance Maintenance Summary Heavy equipment is not required and the use of a vacuum truck is optional when servicing the CIB™. Whether servicing manually or with a vacuum truck, the 15 minute cleaning time facilitated by the Shelf System eliminates the need for confined space entry. Manual Servicing • Remove the manhole cover. • Remove filtration basket either by hand or with manhole hook tool. • Cut zip ties, remove StormBoom™ and dispose. • Attach new StormBoom™ with zip ties. • Brush filtration basket screens clean if necessary. • Replace filtration basket and replace manhole cover. Vacuum Servicing • Remove the manhole cover. • Cut zip ties, remove StormBoom™ and dispose. • Reach into filtration basket with vacuum truck hose and suction out debris. • Attach new StormBoom™ to skimmer tray with zip ties. • Replace filtration basket and replace manhole cover.

Grate Inlet Skimmer Box™ (GISB™) General Information The Grate Inlet Skimmer Box™ (GISB™) is a specialized inlet filter used specifically for grated catch basins. The unit is made of marine grade fiberglass and stainless steel to ensure longevity and durability. During a storm event, all incoming stormwater passes through the internal skimmer tray and into contact with a hydrocarbon absorption boom. Stormwater and solid material then fall into the lower section of the skimmer box where small sieve sized filters capture and retain all solids. Turbulence deflectors within the filtration box act to calm the water and allow for a greater removal efficiency. Purified stormwater is thus able to pass into the catch basin system allowing the filters to dry after each storm event. Benefits • Will not impede design flow of the inlet. • Captures hundreds of pounds of debris and sediment. • Screens of different sieve sizes optimize filtration and flow. • Bypass openings prevent clogging. • Interior components are easily removed to allow access to the lower chamber. • Removes more than 80% of total suspended solids • No need to enter the confined space of the catch basin. • Easily serviced by vacuum truck.

GISB™ Specifications Common Size GISB™ Flow Rate Specifications The maximum flow rate of the Grate Inlet Skimmer Box™ is determined by the amount of flow that can pass through the throat, the exception is found only in very large units. For instance, if the potential flow through the throat is less than the potential flow through the bypass, then the throat determines the maximum flow. However, if the potential water flow through the bypass is more than the throat, then the bypass determines the maximum flow. Filtered flow represents the potential flow rate through all screens and does not include the potential flow through the bypass. Water flow through the bypass happens only when the flow rate through the grate exceeds the flow rate through all the screens or the filtration basket is full. 12-12-12 12 12 12 0.5 2.1 1.0 15-30-25 15 30 25 0.54 18.5 6.6 I-24-24-25 24 24 25 4.4 4.0 4.0 A-24-37-25 24 37 25 10.2 21.1 8.7 C-28-37-25 28 37 25 12.2 19.4 7.4 36-36-25 36 36 25 18.8 23.4 13.4 E-36-54-18 36 54 18 37.6 27.8 15.0 S-46-39-18 46 39 18 38.2 28.1 14.8 F-48-30-18 48 30 18 22.5 22.6 10.4 G-52-58-18 52 58 18 89.3 40.1 25 H-78-36-18 78 36 18 67.1 50.6 25.1 GISB Model # Width (Inches) Length (Inches) Depth (Inches) Throat Filtered Flow (cfs) Bypass Flow (cfs) Inlet Filters | Catch Basin Inserts Operation and Maintenance Manual 08 *GISB™ flow rates are based on common size units, however, custom size units are available. GISB™ Operation Operation Summary 1 Stormwater enters the inlet through the grate and passes through the StormBoom™ installed around the basket top. 2 Throughout the storm event, water continues to come in contact with the StormBoom™ and then flows into the lower filtration chamber. 3 As the storm intensity increases, the water level in the GISB™ rises to an adjacent level with the medium size sieve screens and turbulence deflector. 4 If the storm intensity becomes a high flow event, the water level in the GISB™ rises to a level adjacent to the coarse sieve size screens above the turbulence deflector. 5 If the stormwater flow rate is extreme or the GISB™ is full where it exceeds flow through all the screens, the water will bypass the screens by passing through skimmer protected openings at the top of the GISB™. 6 After the storm event has subsided, the stormwater will drain from the GISB™, leaving all collected debris suspended in the basket to dry until removal during routine maintenance. Inlet Filters | Catch Basin Inserts Operation and Maintenance Manual 09 GISB™ after storm event, full of debris and discolored StormBoom™ indicating the need for service and replacement. GISB™ Maintenance Maintenance Summary The Grate Inlet Skimmer Box™ is recommended to be inspected and serviced quarterly. However, site conditions can affect the service interval to be either longer or shorter than the quarterly recommendation. The maximum flow capacity of the Grate Inlet Skimmer Box™ will be restored after each servicing. The flow rate through the unit will be the same as a new one no matter the times serviced due to the durable stainless steel construction of the GISB™ The unit can easily be serviced manually or with the assistance of a vacuum truck.

Environmental policy is the commitment of an organization or government to the laws, regulations, and other policy mechanisms concerning environmental issues. These issues generally include air and water pollution, waste management, ecosystem management, maintenance of biodiversity, the protection of natural resources, wildlife and endangered species. Concerning environmental policy, the importance of implementation of an eco-energy-oriented policy at a global level to address the issues of global warming and climate changes should be accentuated. Policies concerning energy or regulation of toxic substances including pesticides and many types of industrial waste are part of the topic of environmental policy. This policy can be deliberately taken to direct and oversee human activities and thereby prevent harmful effects on the biophysical environment and natural resources, as well as to make sure that changes in the environment do not have harmful effects on humans.
