"Curb” your enthusiasm! - Introducing EMMA

Stormwater management is an essential component of urban infrastructure, ensuring cities remain safe, clean, and compliant with environmental regulations. EnviroPod has introduced a cutting-edge solution specifically designed for the North American market: the Easy Manhole Maintenance Access (EMMA) Curb Inlet Filter. EMMA is engineered to handle high flow rates while efficiently trapping trash and debris, providing a robust solution for municipalities. In this blog, we’ll explore the features and benefits of EMMA, compare its performance to alternative trash capture devices, and highlight why it’s the superior choice for modern stormwater management.

EMMA Curb Inlet Model Features

The LittaTrap™ EMMA Curb Inlet Filter model is designed to convey stormwater runoff from the curb inlet opening to the LittaTrap™ basket, with the basket positioned directly under the manhole access opening. This design offers several key advantages:

• Modular and Adjustable Design: Fits any curb entry catch basin.
• Fast Installation: Quick and straightforward setup.
• Large Capacity: Handles significant amounts of debris.
• Easy Maintenance: Simplifies routine upkeep.
• No Confined Space Entry: Enhances worker safety.
• Full Access: Maintenance crews can access the LittaTrap™ basket from the surface.
• High Flow: Manages high flow rates effectively.

High Flow Rate Management

One of the standout features of EMMA is its ability to manage high flow rates effectively. Unlike typical trash capture devices that can become obstructed, leading to the risk of flooding, EMMA is designed with an extended bypass weir that allows greater hydraulic capacity than other trash capture devices. Where trash capture devices that cover the outlet pipe typically have a short bypass weir, the bypass weir of EMMA is longer than the catch basin inlet and set at a level that ensures no backwater onto the road.  These features mean EMMA can bypass high flows through the catch basin and into the outlet pipe without restriction or a reduction in the capacity of the catch basin, significantly reducing the risk of flooding.  EMMA is a reliable choice for municipalities dealing with heavy rainfall and high stormwater volumes.

Easy Inspection and Maintenance

Maintaining stormwater infrastructure can be a challenging and costly task, especially when it involves confined space access. EMMA simplifies this process with its above-ground inspection and maintenance capabilities. The configuration allows for easy access via the manhole cover in the pavement, eliminating the need for workers to enter confined underground spaces. This not only enhances safety but also streamlines the maintenance process, making it more efficient and less labour-intensive. 

Compliance with FTC Requirements

Compliance with Full Trash Capture (FTC) requirements is a critical concern for municipalities aiming to reduce pollution and protect waterways. EMMA provides a solution that not only meets but exceeds these requirements. By efficiently trapping trash and debris while allowing high flow rates to bypass, EMMA ensures that municipalities can maintain compliance without compromising on performance or safety.

Lightweight, Robust, and Easy to Handle

EMMA is not only effective but also practical. Its lightweight and robust design makes it easy to handle, install, and maintain. This is particularly beneficial for busy municipalities that need to manage their stormwater infrastructure efficiently and cost-effectively. By reducing the complexity and cost associated with installation and maintenance, EMMA offers a sustainable solution that municipalities can rely on for years to come.

Comparing EMMA to Other Trash Screening Devices

Typical trash capture devices come with several limitations, particularly regarding blockage and maintenance challenges. Here’s how EMMAoutperforms other trash capture devices:

• Flow Rate Management: While other trash screening devices may have a short bypass weir and can become blocked or cause flooding, EMMA’s bypass weir and set level within the catch basin ensures unrestricted water flow, significantly reducing flood risks.
• Maintenance Access: Other trash capture devices often require confined space entry for maintenance, which is hazardous and costly. EMMA’s above-ground access eliminates these risks and simplifies the process.
• Compliance and Performance: EMMA provides superior performance in trapping litter and debris, ensuring compliance with FTC requirements more effectively than traditional trash capture devices.
• Lightweight, Robust, easy handling: Some trash screen devices are made from heavy materials making them difficult to handle, install and maintain. The EMMA design eliminates these issues.

EMMA represents a significant advancement in stormwater management technology. Developed by EnviroPod for the North American market, its ability to handle high flow rates, ease of maintenance, compliance with FTC requirements, and practical design make it a superior choice compared to other trash screening devices. For municipalities looking to enhance their stormwater infrastructure, EMMA offers a reliable, efficient, and cost-effective solution that ensures clean, safe, and compliant urban environments.
