Soil erosion is a problem due to increased development and ongoing construction projects. Inlet protection helps mitigate the negative effects of soil erosion that results from soil disturbance on New Jersey construction sites.

When buildings are constructed, the land is ripped up and dug out, exposing the soil to possible erosion. Sediments dug up during construction can find their way to the city’s water system through storm sewers, storm grates and storm inlets. This includes large projects and small projects.

Siltsack for Storm Drain Inlets

Siltsack inlet protection is a sediment control device used to prevent silt and sediment from entering your drainage system. It catches the silt and sediment while allowing water to pass through freely.

Siltsack can be used as a primary or secondary sediment control device to prevent failure of your drainage system due to clogging. It must be maintained on a regular basis to function properly. Regular maintenance is essential to remove sediment build-up and ensure the Siltsack remains effective.

Because of the potential danger to our environment, contractors are required to use a professional-grade inlet filter and to use sediment control solutions and measures on all projects. Besides silt sacks, additional inlet protection solutions include rock socks, sediment control logs, and silt fence, or other materials approved by the local jurisdiction.

Understanding the Basics of Inlet Protection

Inlet protection prevents sediment, debris, and other contaminants from entering stormwater drainage systems. This temporary sediment control measure diverts water laden with pollutants away from the drainage system, preventing clogs in storm sewer inlets and local streams, safeguarding the environment by maintaining water quality.

Inlet protection devices can be installed in catch basins, curb inlets, and storm sewer inlets. They are typically used in areas with unstable land, such as construction sites, utility work areas, and landscape renovations, ensuring that debris and pollutants are managed effectively.

The Benefits of Securing Your Job Site with Inlet Protection

Regular maintenance is crucial to remove sediment build-up from inlet protection devices to maintain their safety and efficacy.

Compliance with Regulations

Environmental regulations require inlet protection measures. Proper installation and maintenance help you avoid potential fines and delays associated with non-compliance.

Water Quality Preservation

By effectively filtering and trapping sediment, inlet protection contributes to preserving water quality. Drainage inlets and catch basins are commonly used in parking lots to manage excess stormwater runoff, ensuring efficient drainage solutions in both sag and on-grade configurations.

Long-Term Cost Savings

Investing in inlet protection upfront can save you money in the long run. By preventing sedimentation in stormwater systems, you reduce maintenance costs and potential damages to downstream infrastructure.

Maintaining Project Schedule

Sediment runoff can lead to delays and disruptions on the job site. Inlet protection helps keep your project on schedule by minimizing the impact of erosion and ensuring a stable work environment.

Identifying Different Inlet Types for Effective Protection

There are several types of storm drain inlets that can be used for effective inlet protection, each serving a specific purpose:

  • Curb Inlets: The most common type of storm drain inlet, curb inlets are typically used in urban areas to capture stormwater runoff from streets and sidewalks.
  • Curb Grate Inlets: Similar to curb inlets, these inlets feature a grate or screen to capture debris and sediment, preventing them from entering the drainage system.
  • Drop Curb Inlets: Designed for areas with heavy stormwater runoff, drop curb inlets are capable of capturing large amounts of water, making them ideal for high-flow situations.
  • Combination Inlets: Used in areas with high stormwater runoff, combination inlets are designed to capture both stormwater and debris, ensuring comprehensive protection.

Choosing the right type of inlet is essential for effective inlet protection, as it ensures that the specific needs of the drainage area are met.

Innovative Methods to Safeguard Your Construction Site

Several techniques can be employed for effective inlet protection, each designed to capture sediment and other contaminants before they enter the drainage system:

  • Inlet Protection Devices: These devices are specifically designed to capture sediment and other contaminants, preventing them from entering the drainage system. Examples include silt sacks, filter fabric wraps, and coir wattles.
  • Sediment Traps: These traps are designed to capture sediment and other contaminants in stormwater runoff, preventing them from reaching storm sewer inlets.
  • Erosion Control Measures: Implementing erosion control measures, such as silt fences and straw wattles, helps prevent soil disturbance and erosion on construction sites, reducing the amount of sediment that can enter the drainage system.
  • Regular Maintenance: Ensuring that inlet protection devices are functioning properly requires regular maintenance. This includes inspecting and cleaning devices to remove accumulated sediment and debris.

By understanding and implementing these techniques, construction sites can be effectively safeguarded, and water quality can be maintained. Inlet protection is an essential aspect of responsible construction practices, helping to prevent sediment, debris, and other contaminants from entering stormwater drainage systems.

Coir Wattles

These wattles are 6” x 12’ machine fabricated cylinders consisting of 100% coconut fiber encased in a high tensile machine spun bristle coconut coir fiber twine. Coirwattles come with a protective burlap wrapping.

Small in diameter and versatile, coirwattles can be used on slopes, wrapped around culverts, replace straw bales and silt fencing, just to name a few! They slow the flow of water to reduce erosion and slow the run off by interrupting the length of the slope.

Wooden Inlet

Our filter fabric inlet protection consists of a 4×4 wood box frame with holes and rock around the box.

This is used for reducing the amount of silt and debris that may enter a storm water inlet during construction. The stone and wood frame is placed around the storm drain to collect debris as it enters the opening.

  • Chicken wire with stone
  • Coir logs
  • Filter fabric wrap
  • Straw wattles
