Oldcastle BioMod/BioPod
Modular Biofiltration Systems for Stormwater Treatment
Oldcastle BioMod and BioPod deliver flexible, high-performance biofiltration that supports green infrastructure goals.
The Oldcastle BioMod and BioPod systems are advanced biofiltration solutions that combine filtration, sorption, and biological uptake to treat polluted stormwater runoff. These systems remove total suspended solids, dissolved metals, nutrients, hydrocarbons, trash, and gross solids effectively. Designed as proven Low Impact Development (LID) practices, they integrate seamlessly into site drainage while meeting the demands of modern green infrastructure.
Proven Biofiltration Performance
BioMod and BioPod units deliver treatment that is both powerful and consistent, ensuring runoff is managed to the highest standards. Systems are built to handle pollutants under demanding conditions and provide dependable water quality improvements over time. Benefits include:
- Captures sediments, dissolved metals, nutrients, petroleum hydrocarbons, and debris from runoff
- Incorporates natural treatment through biological uptake for long-term performance
- Designed to meet water quality regulations and improve downstream conditions
Flexible and Sustainable Design
Each system is created with adaptability in mind, allowing layouts to respond to the unique challenges of different sites. The design promotes lasting reliability by balancing functional needs with environmental goals across urban, suburban, and commercial environments. Advantages include:
- Modular systems can be adapted to fit a range of site requirements
- Accommodates diverse plantings to align with landscape and green infrastructure goals
- Blends into urban, suburban, or commercial environments without sacrificing performance
Engineered for Integration
BioMod and BioPod units are designed for seamless integration into standard drainage systems, making installation straightforward and efficient. Their compact footprint conserves valuable site space, while the modular design streamlines construction and adapts easily to diverse project conditions. By simplifying installation and maximizing usable land, these systems help projects achieve compliance goals and long-term sustainability.
Advanced Biofiltration for Modern Infrastructure
Stormwater treatment is shifting from basic compliance to a driver of site performance and community value. BioPod® and BioMod® embody this evolution by delivering compact systems that support green infrastructure goals while fitting within the tight constraints of modern development. Their modular design and flexible integration let engineers and owners add advanced treatment without sacrificing buildable space.
Living Filtration in Action
Rather than a single barrier, these systems combine multiple layers of treatment in one footprint. Flow passes through chambers and components that work together, moving from coarse debris capture to fine filtration and biological polishing. The result is a seamless, efficient process engineered for reliable outcomes under a variety of site conditions.
- Incoming runoff enters the structure, where large debris and floatables are separated early.
- Water then passes through staged filtration targeting finer particles and dissolved contaminants.
- A planted surface layer completes treatment, supporting biological uptake and enhanced polishing.
- Clean water exits through the underdrain, providing safe and dependable discharge.
Where BioPod and BioMod Deliver the Most Value
Adaptable by design, these systems add value across a wide spectrum of projects. Their compact size suits space-limited sites and redevelopment, while their ability to integrate into landscapes supports community-focused green design. Applications include:
- Urban infill sites where land is scarce but water quality compliance is required.
- Retrofit projects replacing outdated stormwater controls to meet higher standards.
- Commercial or mixed-use developments where visible green features also serve as treatment systems.
- Municipal programs seeking consistent results while embedding sustainable practices.
Upstream & Downstream Allies of BioMod/BioPod
BioMod and BioPod excel at bioretention and biofiltration, but they achieve peak performance when paired with complementary solutions that prepare flows upstream and manage water downstream. Together, these products form a resilient treatment train—capturing, cleaning, and controlling stormwater more effectively across the site.
- Rain Guardian units sit right at the curb inlet, catching trash, leaves, and grit before they can choke the bioretention cell. By stopping debris at the door, they keep BioMod and BioPod running freely over the long term.
- PreTX chambers go upstream to take the first hit of stormwater, calming flows and settling out heavy sediment and hydrocarbons. That early treatment clears the way for the bioretention media to focus on fine pollutants.
- R-Tank provides downstream muscle, storing excess clean runoff for infiltration or controlled release. The added capacity helps prevent flooding and makes full use of onsite water management.
- PermeCapture works below the surface to hold and infiltrate treated flows. Its subsurface storage adds another layer of protection while reinforcing the performance of BioMod and BioPod.
- Filterra Bioscape steps in on landscape-driven projects, pairing green infrastructure aesthetics with nutrient removal. It extends the visual and functional value of BioMod and BioPod in settings where design matters.
Confidence Backed by Testing and Field Use
Performance is proven in both lab and field. BioPod and BioMod are validated through independent testing and real-world installations, demonstrating reliable pollutant reduction over time. These results build regulator confidence and give owners assurance that systems will continue delivering measurable outcomes year after year.
- Independent evaluations confirming sustained water quality improvements.
- Demonstrated reliability in diverse site conditions.
- Documented performance aligned with stringent regulatory benchmarks.
- Long-term consistency that reduces the risk of costly compliance failures.
