Storm Drain Guards & Stormwater Protection

A storm drain grate is the metal or polymer cover placed over a storm drain opening to allow water to flow in while blocking large debris. In stormwater protection, inlet protection devices are often installed beneath or around these grates to provide an additional layer of sediment filtration and prevent clogging or contamination.

Storm drains can be protected using inlet protection devices such as below-grate filter bags, curb inlet barriers, or frame-and-filter systems. Products like the EZ-Catch install below the grate, while the Wimco Road Drain features a curved back that blocks stormwater and sediment at the curb line. Selection depends on drain type and site conditions.

Available options include below-grate devices like the EZ-Catch, customizable filter bags such as the FleXstorm, and curb-and-gutter barriers like the Wimco Road Drain. These systems accommodate drop inlets, curb inlets, and round inlets, making them suitable for a wide range of construction and municipal drainage structures.

Yes, many inlet protection devices offered by Coleman Moore Company are designed for reuse. Reusable systems like the FleXstorm filter bag can be cleaned and reinstalled across multiple project phases, reducing material costs and waste. Their flexible construction allows them to fit varying drainage casting sizes throughout a job site.

Inlet protection is typically required on construction sites as part of a Stormwater Pollution Prevention Plan (SWPPP) or under state and local permit conditions. They must be installed wherever stormwater runoff could carry sediment into a storm drain. Iowa-based contractors should verify requirements with the Iowa DNR and applicable municipal standards.

Choosing the right device depends on the type of drain (curb inlet, drop inlet, or round inlet), the volume of expected runoff, and the level of sediment filtration required. Coleman Moore Company offers product selection consultation to help contractors and engineers identify the best solution for their specific site conditions and regulatory requirements.
