Modular Storm Water Trough Filter for Variable Inlet Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter systems for storm water drainage systems are not configurable to accommodate the various widths and shapes of curbside openings in storm water catch basins, and they often require custom manufacturing to align the filtering medium with the vault access opening for easy maintenance.
Innovation Solution
A configurable storm water open-curb inlet trough filter system that includes interconnecting components of various lengths and configurations to fit multiple standard open-curb inlet sizes, allowing the system to be easily assembled and expanded to cover the full width of the curbside opening, with a removable filtering apparatus positioned directly under the manhole cover for convenient maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional filter systems are used in storm water catch basins, then filtering debris and sediment is achieved, but the system cannot accommodate various widths and shapes of curbside openings without custom manufacturing
Solution Approach 1:
The filter system is divided into modular components including a filter housing, filter media section, and support structure that can be assembled in different configurations. The housing includes adjustable walls and a base plate with mounting holes that can be positioned to accommodate various curbside opening widths and shapes, eliminating the need for custom manufacturing while maintaining adaptability.
Solution Approach 2:
The filter system incorporates adjustable elements such as movable walls, repositionable support structures, and flexible mounting mechanisms that allow the filter to be dynamically configured to match different curbside opening dimensions. This dynamic adjustability enables the same standardized filter to adapt to various opening configurations without requiring custom manufacturing.
2Reliability
If the filter system is designed to extend across the full width of the curbside opening, then all storm water is captured, but the structure becomes complex and difficult to install
Solution Approach 1:
The filter system uses segmented modular components including a base plate, adjustable walls, and a filter media section that can be assembled step-by-step. The base plate provides a stable foundation with mounting holes for positioning, and the adjustable walls can be independently positioned to extend across the full width of the curbside opening, achieving complete water capture without excessive structural complexity.
Solution Approach 2:
The filter housing includes pre-configured mounting holes in the base plate and pre-positioned adjustable walls that can be quickly assembled to the required configuration before installation in the catch basin. This preliminary configuration allows for rapid installation while maintaining the ability to extend across the full width of the opening for reliable storm water capture.
3Reliability
If the filtering apparatus is positioned away from the manhole cover, then filtering function is maintained, but maintenance access becomes difficult
Solution Approach 1:
The filter system incorporates a removable filter media section that can be dynamically accessed and removed through the manhole cover opening. The adjustable walls and support structures are designed to allow the filter media to be easily pulled out for cleaning or replacement when the manhole cover is removed, maintaining filtering function while providing convenient maintenance access without requiring the filter to be permanently positioned away from the access point.

AI summary
A storm water trough filter system is mountable in a storm vault having interior walls and a storm water inlet formed in at least one of the interior walls which allows storm water to flow therethrough and into the storm vault. The storm water trough filter system has at least one trough section which defines a water trough for receiving storm water flowing into the storm vault through the storm water inlet thereof. The storm water trough filter system further includes at least one mounting bracket which is affixable to at least one of the interior walls of the storm vault, the at least one trough section being mountable on the at least one mounting bracket. The storm water trough filter system further includes a filtering apparatus having a water permeable filtering medium. The water trough defined by the at least one trough section is in fluid communication with the water permeable filtering medium of the filtering apparatus to direct storm water received by the water trough to the filtering medium of the filtering apparatus.
