Solution Overview
Problem
Existing storm water interceptors struggle to efficiently handle elevated volumes of storm water, often allowing bypass and increasing pollution levels in water bodies, while also being difficult to install and maintain.
Innovation Solution
A storm water interceptor system featuring a treatment tank with an aluminum grate and modular pre-cast concrete sections, along with a secondary treatment tank and efficient conduit configurations, to effectively separate oils, grit, and debris from storm water, even during high flow volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional oil/grit separators are used to separate sediment and oil from storm water, then separation function is provided, but they cannot accommodate high or elevated volumes of storm water efficiently and allow bypass
Solution Approach 1:
The treatment tank is divided into multiple chambers (first chamber, second chamber, third chamber) with specific functions for different separation processes. This segmentation allows the system to handle high volumes while maintaining separation efficiency through distributed processing zones.
Solution Approach 2:
The outlet conduit is positioned at a higher elevation than the inlet conduit, creating a vertical dimension change. This elevation difference enables the system to maintain separation efficiency during high flow by utilizing gravity-driven flow control and preventing bypass through strategic positioning of conduits at different heights.
2Productivity
If multi-chambered oil/grit interceptors with large tanks are used, then separation capacity is increased, but they become cumbersome to install requiring cranes with long booms
Solution Approach 1:
The treatment tank is segmented into multiple modular chambers that can be assembled on-site. This modular approach maintains the separation capacity of large multi-chambered interceptors while enabling easier installation without requiring cranes with long booms, as each module can be maneuvered into position more readily.
3Adaptability or versatility
If complex interconnections and barriers are used in modular separators, then separation functionality is enhanced, but installation becomes more difficult
Solution Approach 1:
The inlet conduit extends through the treatment tank to deliver storm water directly to the second chamber, merging the flow path with the chamber structure. The outlet conduit is strategically positioned to receive flow from multiple chambers. This merging of conduit functions with chamber structures provides enhanced separation functionality while simplifying installation by reducing the number of separate connection components.
4Ease of operation
If weirs are used in prior art configurations, then flow control is provided, but they permit storm water to flow untreated directly through during high water volumes
Solution Approach 1:
By positioning the outlet conduit at a higher elevation than the inlet conduit and configuring it to extend below the aluminum grate, the system uses vertical positioning to control flow. This elevation-based control prevents bypass during high flow volumes by requiring water to traverse the full treatment path, while still allowing efficient flow control through gravity-driven mechanisms.
