Inlet protection on construction projects is a temporary best management practice (BMP) used to prevent sediment, trash and debris from entering storm drains. If you’re wondering what kind of inlet protection you need for your project, you’ll first need to consider a number of important factors and then select the option best suited for your specific site.


Factors to Consider

When choosing the type of inlet protection to install on a construction project, take the following into consideration:

  1. Types of inlets
  2. Location of the inlets
  3. Drainage areas
  4. Types of pollutants that may potentially enter the inlet
  5. Installation requirements
  6. Maintenance requirements

There are currently a variety of products on the market that provide an array of options for inlet protection. However, often times a simple low-tech solution for inlet protection is adequate and cost effective. Be sure to choose inlet protection that works best for your specific site conditions. Always install inlet protection prior to any soil disturbance. Additionally, it is crucial that all inlet protection is inspected regularly and maintenance is conducted as needed.

Ultimately, the key to preventing potential pollutants from leaving a construction project is choosing proper BMPs throughout the entire project.
