Effective stormwater management requires looking beyond initial installation costs. While many stormwater treatment systems have similar regulatory performance standards, their long-term operation and maintenance requirements can vary significantly depending on the system’s design, footprint, and technology. This is especially true when comparing traditional bioretention with proprietary high-rate biofiltration systems such as Contech’s Filterra Bioretention System and similar systems.

As urban development intensifies and stormwater regulations grow more complex, engineers are challenged to design treatment systems that perform effectively within constrained site layouts. Engineered biofiltration has long been a proven solution, with vertical-flow systems like Filterra® delivering reliable, high-rate performance in compact sites. Building on that foundation, Contech’s Modular Wetlands® Linear (MWL) uses horizontal-flow technology that addresses hydraulic and spatial challenges, giving engineers even greater flexibility in how they design for water quality.
