FocalPoint® High-Performance Modular Biofiltration System (HPMBS) is a compact, scalable stormwater solution that combines engineered soil media with a modular, high-capacity underdrain for superior filtration, infiltration, and water storage. Unlike traditional systems, its expandable underdrain offers unlimited underground detention and reuse potential. Designed for flexibility and reliability, FocalPoint meets strict performance standards with verified post-installation results. Ideal for both new construction and retrofits, it integrates easily with traditional LID BMPs like swales, sidewalk planters, and vegetated areas—making it a smart choice for projects requiring both water quality and volume control.
Jen-Hill Construction offers the best in Water Quality Treatment products. No other company offers a more comprehensive array of products to meet your needs.
The FocalPoint HPMBS is a combination of a high performance, open cell underdrain, a clog-proof bridging mesh, bridging stone, and a high performance biofiltration media that flows at a rate of over 100” per hour. What this unique combination of parts creates is that FocalPoint’s modular design delivers unmatched flexibility in meeting both water quality and volume control requirements. It integrates effortlessly with Low Impact Development (LID) strategies such as bioswales, bioretention, and stormwater planters.
FocalPoint is a high-performance bioretention system that treats large runoff volumes in tight spaces. With infiltration rates of 100″/hr or greater, its engineered soil and modular design drastically reduce footprint, delivering reliable performance in a small package reducing upfront construction costs as well as maintenance costs.
When used in conjunction with complimentary stormwater management solutions, such as bioswales, permeable pavement, and raingardens, FocalPoint creates the ability for developers, architects and engineers to decrease a property’s surface storage volume requirements and increase developable land. Subsequently, with more developed, property owners can increase long-term revenue and/or property value.
Particularly in rural communities, use FocalPoint as part of a distributed detention strategy to extend time of concentration and lower peak flows—reducing required detention volume by 20–50% while meeting water quality goals.
More space. More homes. More value.
FocalPoint unlocks more usable space by working seamlessly with other stormwater solutions like underground detention and large bioretention cells. In urban developments, pair FocalPoint with modular underground detention to treat runoff before storage, reducing the surface footprint of your stormwater infrastructure and freeing up premium land for development.
