Inlet protection has emerged as one of the most important BMP’s for a job site in today’s construction industry. Stormwater inlets are designed to drain the runoff from drainage easements, parking lots, and other impervious surfaces. Drop and curb inlets can be the last line of defense preventing sediment laden runoff from entering the stormwater system. These inlet protection structures can provide filtration, reduced flow velocity, and removal of pollutants. Colonial has many products that can match your needs for either curb or drop inlets. We stock the most common sizes for any municipality and can offer custom sizes on any of the products listed.
Curb Inlet Protection Products
The excelsior log is a lightweight, environmentally friendly, and cost effective option for curb inlet protection. Given the excelsior log’s size and weight, it can easily be installed to cover most any curb inlet size, with overlap. In Curlex sediment logs, the water filters through the logs rather than underneath. The nature of the porous interlocked aspen fiber matrix make this product successful. Excelsior logs can reduce velocity naturally and most importantly collect sediment that might contaminate the water table.
Diamond Sock is a versatile compost filter sock product that has the ability to act as a curb inlet protection device. The filter sock provides filtration of sediment laden runoff through its compost media matrix. It also reduces the sheer velocity of the water before it enters the stormwater system. Diamond Sock provides a unique advantage given its ability to be stored on a continuous pallet. Diamond Sock can meet any curb inlet size through simply cutting off the designated length of the inlet and securing each end with ties. Any moderate to large job size could see major cost savings if an entire pallet is used for all curb and drop inlets. Sand bags and stakes may be used to secure the product in some high flow areas.
The Dandy Curb is a high strength and reusable product for curb inlet protection. The Dandy Curb comes with a pouch of fabric secured with velcro at the base. This pouch is filled with small stones to provide weight and protection against sheer flow. The pouch is attached to a tube covered in high visibility orange monofilament fabric. This tube acts as added protection to prevent runoff from overflowing the apron and entering the storm inlet. The monofilament fabric filters out the sediment laden run off to filter before entering the stormwater system.
Dandy Curb Sack
If you want a curb inlet combined with a drop inlet, the Dandy Curb Sack is the perfect match. The Dandy Curb Sack is supported by the Dandy Curb tube to protect runoff from entering the curb inlet portion. Attached to the curb portion is a dandy sack. It lies below the drop inlet, in front of the curb base. The Dandy Curb Sack provides unmatched protection from suspended solids entering through both the curb and drop sections of any inlet. The sediment laden run off is filtered through the Dandy Sack portion prior to entering the stormwater system. This system provides strong and completely reusable curb and gutter protection.
Travel Lane Wattle
This curb inlet device is filled with pine straw and wrapped in green polyester fabric. Internal sandbags are built in for support and weight. The Travel Lane Wattle is designed for high visibility, high flow and ease of use (handles are built in for easy lifting!) Reuse the wattle when you need stream, inlet or slope protection. All logs are 8” in diameter and available in lengths of 10’, 15’ and 22’ pieces.
Drop Inlet Protection Products
The Dandy Sack features and open face design to allow traffic to move freely above while providing unparalleled runoff protection below. The Dandy Sack is manufactured with high strength monofilament fabric to filter out all suspended solids before entering the stormwater system. It also is sturdy enough to support the high flow volume.
The inlet sentry features an above ground drop inlet protection with its unique “donut” design. Designed by industry experts, the inlet sentry is fabricated of high strength monofilament materials. The sentry’s “International Orange” and white color allows for high visibility, thus easy contractor and inspector monitoring and maintenance. The sentry is constructed with an elastic adjustable grate skirt and overflow ring on the top. This provides a secure multi-flow system for drop inlets that is second to none. The inlet sentry is a unique design that is 100% reusable, and cost effective.
The Dandy Bag is an above ground drop inlet protection device that should be used in applications where mud and deeply saturated aggregate are freely moving. The Dandy Bag is constructed with high strength monofilament fabric to filter out the sediment prior to entering the stormwater system. The bag offers protection above and below and can support the most clogged sediment laden run off on todays job sites. The Dandy Bag is manufactured to fit both round and square grates for most any municipality.
Dandy Pop was designed for field applications to provide high visibility and protection. The unique design provides an alternate protection to the “old school” and time consuming silt fence drop inlet protection. The Dandy Pop can pop up to meet any size grate on job sites and installation takes seconds. The Dandy Pop fully encloses the grate and provides filtration with slowed flow before the suspended solids can enter the storm water system. Sizes fit most standard grates: 32″ x 32,” 36″ x 36″ and 48″ x 48.”
Round Frame and Filter Assembly
The Round Frame and Filter Assembly is a round dome structure designed to fit on top of precast inlets. Unlike other inlet protection devices, the round dome does not require any grate removal; simply set the structure on top of the inlet. The reusable plastic frame is covered with either DOT 2 Stage Filter Fabric or High Flow Filter Fabric. Rock bags are built into the filter and seal the perimeter of the frame. Fill these bags with rock, sand or soil. The light-weight round dome is 60” in diameter.
Low Profile Rectangular Dome
Use the Low Profile Rectangular Frame & Filter Assembly for over grated inlets and cover inlets, no grate removal necessary! The patented dome structure has a proven performance record for median inlet protection and surface ground protection. Just like the Round Frame, the Low Profile Rectangular Frame is reusable and available with either DOT 2 Stage Filter Fabric or High Flow Filter Fabric. Rock bags are built into the filter and can be filled with rock, soil or sand. The Low Profile Rectangular Frame & Filter Assembly is 30” x 46” x 16”.
The pipe stopper is a reusable HDPE device that should be used to reduce or prevent the flow of sediment into stormwater pipes. The Pipe Stopper eliminates the need for silt fence pipe protection. The frame is covered with DOT or High Flow filter fabric that attaches to the frame with friction fingers. The Pipe Stopper is designed to fit inside 15”, 18”, 24” and 30” diameter pipe. Custom sizes are available as well.
