Myth-Busting Five Common Misconceptions About Manufactured Treatment Devices
In stormwater management, manufactured treatment devices (MTDs) are often recognized as innovative solutions for controlling runoff and enhancing water quality. Yet, despite their growing adoption, several misconceptions about these devices persist, leading to confusion and misinformed decisions. This blog will tackle some of the most prevalent myths surrounding MTDs, shedding light on their true capabilities and effectiveness.
All MTDs Are the Same
Not all MTDs are created equal. Different manufacturers use different technology and materials, resulting in different performance characteristics. Understanding each manufacturer's device's specific treatment capabilities and maintenance procedures is essential for effective stormwater management.
MTDs Are Not Cost-Effective
While the upfront cost of MTDs can be higher than that of some land-based solutions, this is often offset by the long-term savings associated with land space savings. Conducting a lifecycle cost analysis to determine the economic viability of a specific project is essential.
MTDs Are Only for Urban Areas
Some assume that MTDs are only necessary in urban environments where space is limited and land-based solutions are not feasible. However, MTDs can also benefit rural and suburban areas where runoff and pollution are concerns, especially near sensitive water bodies.
Only New Development Needs MTD
There’s a notion that MTDs are only necessary for new developments. However, retrofitting existing sites can significantly improve stormwater management and water quality. In addition, MTDs provide increased flow rates, superior pollutant removal, and adaptable installation methods, making these systems particularly well-suited for space-constrained environments.
MTDs Aren’t As Proven As Land-Based BMPs
Most regulatory bodies require third-party performance verification from national testing programs before allowing their use. Conversely, far less performance data is available for non-proprietary BMPs, and much of it proves inferior to that of MTDs.
