Inlet Protection for Stormwater Runoff

When you need temporary inlet protection during construction or other activities, you need filters that are inexpensive and quick to install. At BMPstore.com, we have a huge selection of temporary inlet protectors for catch basins and drop inlets. Among our selection is a set of siltsacks designed for high and medium flow drop inlets, which work as effective catch basins for silt and sediment, reducing clogs in the drainage system while keeping your waterways clear.

Save Time and Money with Our Stormwater Management BMPs

The high quality non-woven geotextile we use is 100 percent water permeable, while still preventing the passage of even the finest sediments. The durable and highly permeable nature of these materials allows effective filtering for even sudden surges of water, catching potential pollutants in stormwater runoff and preventing drainage system clogs for reduced maintenance. Our BMPs come in various designs ideal for stormwater management, working with a curb inlet or hanging from the drop inlet grate for an effective debris solution in a variety of situations. Take a look around our store and you’ll find a variety of BMPs to help you save time and money.

Regular Flow Siltsack Type A Regular Flow Siltsack Type B Hight Flow Siltsack Type A

The Regular Flow Siltsack is a sediment control device designed for drop inlet filters. The Siltsack is made of a permeable geotextile that allows water to pass but prevents silt and sediment from clogging the drain system.

The Type B Regular Flow Siltsack is a sediment control device designed for combination drains where a drop inlet is coupled with a curb inlet. The Siltsack is made of a permeable geotextile that allows water to pass but prevents silt and sediment from clogging the drain system.

The High Flow Siltsack is a sediment control device that hangs from the drop inlet grate and is made from a permeable geotextile designed to handle strong surges of water. The Type A High Flow Siltsack prevents silt and sediment from clogging drain systems.
High Flow Siltsack Type B Siltsack Type C Grate Gator Type A

The Type B High Flow Siltsack is a sediment control device that hangs from the drop inlet grate and is made from a permeable geotextile designed to handle strong surges of water. The Type B Siltsack is made particularly for combination drains where a drop inlet is coupled with a curb inlet.

The Type C Siltsack is the newest addition to the Siltsack family. It offers the same permeable geotextile as a High Flow Siltsack but features an adjustable frame to fit almost any size grate! This unique new design allows for quicker installation and reuse over multiple grate sizes.
The Type A Grate Gator is an "over the grate" storm water filter that uses an elastic skirt to easily slip over any grate. The Grate Gator is designed to remove sediment and debris from storm water as it enters the catch basin.
Grate Gator Type B SediBag Grate Pyramid Type A
The Type B Grate Gator is an "over the grate" storm water filter that uses magnets to easily attach to any grate. The Grate Gator is designed to remove sediment and debris from storm water as it enters the catch basin.

The SediBag catch basin filter removes sediment, trash and debris from storm water entering a catch basin. The unit slides over the storm grate like an envelope and the grate is placed back in the frame recess. The built-in lift straps make removal and replacement of the grate an easy process.


The Grate Pyramid attaches easily to any inlet grate with provided attachment hooks. The high flow filter skirt prevents sediment and debris from entering the drain system while still allowing water to pass through. The unit can be cleaned and stored for reuse.
Ultra-Drain Guard Oil & Sediment Model Ultra-Drain Guard Oil & Sediment Plus Model Filter Sock

Drain Guards keep sediment and other pollutants from entering the water system. The Oil & Sediment Model removes up to .87 gallons of hydrocarbons as well as dirt, sand and other contaminants.

Drain Guards keep sediment and other pollutants from entering the water system. The Oil & Sediment Plus Model features Ultra-X-Tex filter strips that increase hydrocarbon removal.

The Filter Sock stops harmful substances from entering the stormwater system. The woven polymer casing allows water to pass through quickly while filtration media inside removes pollutants. All units are 9' lengths and can be overlapped for longer coverage.
Gravel Bags Basin Guard Drain Plug

These heavy-duty bags provide quick and easy sediment and erosion control. Gravel bags are a basic BMP used to meet regulatory requirements for stormwater and erosion control. The sizes and industry standard allow the user to fill them up with as much or as little gravel (not included) as the application requires.

The Basin Guard replaces messy hay bales and keeps sediment and oil from entering drains and inlets. This unit comes in two separate designs, a 36" diameter round unit and a 4' x 6' rectangular unit. The Basin Guard prevents silt, sediment and hydrocarbons from entering storm drains while also providing visual indicators to storm drain locations.

The Drain Plug will keep spills out of drains. The urethane plugs have a tapered design that wedges securely into standard drains to stop any flow. The Drain Plugs are made with eyebolts that are removable. The flexible polyurethane material resists oil, water and most aggressive chemicals and is non-absorbing, making it easy to clean with soap and water.
Drain Seal Drain Seal Plus Drain Seal - Clear Model

The Drain Seal is made of a unique, urethane material that allows the pad to deform and seal off most drains to stop spills from going down the drain. The Drain Seal is flexible and non-absorbing, designed to resist oils, water and most aggressive chemicals. There is no specified "top" or "bottom" to this unit, both sides will quickly and temporarily seal to any smooth surface.

The Drain Seal Plus protects drains from spills but is designed to left outside long-term. The Drain Seal Plus is made up of two layers. The bottom layer is made up of flexible, non-absorbing urethane that is reinforced with tear resistant mesh and works to keep spills from entering drains. The top layer is a rugged, reinforced polyethylene layer that provides protection from extended UV exposure and vehicular traffic.

The Clear Model of the Drain Seal allows respondents to see spills are being stopped. This unit serves the same purpose as the Drain Seal but is made of clear material to provide an unobstructed view of covered drains. The Clear Model is made of the same unique, urethane material that allows the pad to deform and seal off most drains - temporarily "sealing" off any smooth surface.
