WHY THESE PRODUCTS?

Decentralized treatment options are the basis of Low Impact Development, but can also be utilized in a traditional stormwater management regime. Treating water where it falls can greatly improve the economics of your stormwater quality management plan on site. Our approach at Construction EcoServices is to look at the site in its entirety and find out what design strategy best fits the end user. Questions like “How long do you anticipate owning the property” and “How many outfalls and inlets will the property have” are critical in determining what the best course of action is. Where less than 15 inlets are on a site or there are multiple outfalls, often times a decentralized approach will save your client in both upfront costs and long-term maintenance costs.

​Grate Inlet Skimmer Box™ (GISB™​)

Inlet Filter Specifically for Grated Catch Basins

Why Do We Recommend This Product?

“GISBs are both easy to maintain and easy to install. They typically only have to be cleaned out twice a year, while other “equivalent” products (typically made of mesh) need to be cleaned far more frequently. In addition, all things being equal, GISBs will outlast any other solution.”

About the Grate Inlet Skimmer Box™

The Grate Inlet Skimmer Box™ (GISB™) is a specialized inlet filter specifically for use in 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 runoff passes through the internal skimmer tray and into contact with a Stormboom™. 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 passes through the catch basin allowing the filtered materials to dry after each storm.

Highlights:​

  • Durable UV coated fiberglass body with stainless steel filter screens. Engineered to be a permanent component of the infrastructure.
  • Multiple sieve size screens result in efficient pollutant removal without the need for bag or cartridge filters.
  • Non scouring design: turbulence deflectors calm rushing water inside the filter screen system to prevent sediment scouring.
  • Servicing is quick and simple via vacuum truck with no risk or damage to screens.

BENEFITS

  • Optimized filtration: multiple sieve size screens enhance filtration
  • Built strong: fiberglass and stainless steel construction​
  • Full capture for trash TMDL’s
  • Bypass openings prevent clogging issues
  • Will not impede inlet flow
  • No need for confined space entry
  • Removes more than 80% TSS
  • Easy vacuum truck servicing

​Fabco Beehive Filter

Rain Garden Beehive Filter Basket

About the Beehive

gallery-beehive-2Most rain gardens are designed to only capture the first inch of rain. So in any rain garden design, some type of overflow mechanism should be considered in order to prevent erosion and other potential damage from flooding.

Installing an overflow riser pipe and discharge pipe is a simple solution. However, the system needs to be protected from coarse floatables (such as mulch, organic materials and trash) that could lead to clogging and possibly flooding.

Beehive (or Rain Garden overflow) filter is the perfect solution for this application. It can be added to capture floatables and solids in any type of round bypass infrastructure.

Key Elements:

  • An expansion ring (plastic or aluminum) which is sized to fit inside the riser pipe
  • Geotextile filter bag with a mounting frame, and a support ring which connects the filter bag to the flange

Simple Installation:

  • Insert the properly sized expansion ring into the riser pipe to the desired depth and clamp the ring firmly into position
  • Place the assembled filter bag on top of the expansion ring
  • Put the beehive grate or flat grate back on top of the riser

BENEFITS

  • Simple, durable, corrosion resistant construction
  • Sizes to fit most pipes: 8” up to 36” ID – short and long bags available
  • Fast, simple installation – no worries about grate/frame compatibility
  • Cost-effective protection for high flow operation
  • Reduces clogs – keeps sediments and debris out of underground pipes
  • Quick clean out –beehive filter lifts up and out for servicing

​Curb Inlet Basket™ (CIB™​)

Inlet Debris & Sediment Filter

About the Curb Inlet Basket

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 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. Both inlet filters are unique for their shelf system which directs storm water flow into the filter positioned directly under the access manhole. This system can be manufactured to any size and style of catch basin. The Standard Curb Inlet Basket and High Capacity Curb Inlet Basket are multi-stage filtration systems that can capture a variety of pollutants and debris during a storm event. Under high volume flows, water can bypass the filtration system by flowing past the filter and into the catch basin.

Operation Summary:

  • Storm water carrying debris and pollutants enters through the curb inlet.
  • 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.
  • The water flows over the weir and into the filtration basket, filtering out trash, sediment and hydrocarbons.
  • Filtered water leaves the basket and enters the catch basin. The position of the curb inlet basket high in the catch basin allows for captured debris to dry between storm events and avoid restriction to upstream pipes.

Highlights:

  • Durable UV coated fiberglass body with stainless steel filter screens. Engineered to be part of the permanent infrastructure
  • Multiple sieve size screens result in efficient pollutant removal
  • Non scouring design: turbulence deflectors calm rushing water inside the filter screens to prevent scouring
  • Servicing is quick and simple via vacuum truck with no risk or damage to screens

BENEFITS

  • Filters stormwater entering shallow or deep curb inlets and catch basins
  • Multi stage filtration captures an array of contaminates​
  • Built strong: fiberglass and stainless steel construction
  • Easy maintenance: service via vacuum truck or manually
  • Full capture for trash TMDL’s
  • No need for confined space entry

Fabco Connector Pipe Screen

Catch Basic Insert Filter

About the Connector Pipe Screen

A Connector Pipe Screen (CPS) is a catch basin insert filter that is designed to capture trash. Unlike other catch basin inserts that are typically installed closer to the inlet (under the drain grate or below the curb opening), CPS inserts are installed in front of the catch basin’s outlet pipe – trapping trash and debris inside the catch basin while allowing filtered stormwater to exit into the storm drain infrastructure.

CPS insert features:

  • Manufactured from perforated, 14 gauge, 304 stainless steel sheets
  • Perforations have a 5 millimeter diameter – screen has an open area greater than 50%
  • CPS net open area (when converted to an equivalent pipe diameter) exceeds the actual diameter of the outlet pipe leaving the catch basin – CPS can pass more volume than the outlet pipe it covers
  • Overflow / bypass prevents flooding if screen becomes blocked or covered
  • The CPS is designed to cover a specific pipe diameter – its size does not depend on the size of the catch basin drain. The CPS is a compact, affordable product that is easy to install and adaptable over a wide range of catch basin sizes and styles.
  • The design utilizes very little space, maximizes the trash storage capacity within the catch basin and allows for easy maintenance.

About preTX

Keep your biofilters, bioretention and subsurface infiltration systems clean.

PRETX is available in several different configurations, enables the simplified maintenance of green infrastructure systems at the inlet in a deep sump catch basin that is accessible and requires no specialized maintenance equipment. The absence of a pre-filter may allow sediment, trash and debris to prematurely clog the biofilter media or infiltration bed. Surface accumulation of trash and debris can require frequent maintenance for aesthetics in high loading land uses and reduce the infiltration rate of filtration media. Installation is simple and comparable to common catch basins and grates.

BENEFITS

  • Optimized filtration: multiple sieve size screens enhance filtration
  • Built strong: fiberglass and stainless steel construction​
  • Full capture for trash TMDL’s
  • Bypass openings prevent clogging issues
