FocalPoint® combines independently reviewed water-quality performance with a certified media infiltration rate of 400 inches per hour, giving civil engineers a compact, flexible biofiltration option for constrained sites, urban retrofits, transportation corridors, commercial developments, and municipal infrastructure.
Now certified by the New Jersey Department of Environmental Protection as an 85% TSS removal Manufactured Treatment Device, FocalPoint gives design teams documented performance assumptions they can use with greater confidence.
NJDEP-CERTIFIED PERFORMANCE. GREATER DESIGN FLEXIBILITY.
Civil engineers are routinely asked to deliver more treatment performance within less available space.
FocalPoint® High-Capacity Modular Biofiltration provides a compact green-infrastructure solution backed by formal NJDEP certification as an 85% TSS removal Manufactured Treatment Device. Its certified media infiltration rate of 400 inches per hour, or 4 gpm per square foot, allows more water-quality flow to be treated within a smaller surface footprint than conventional low-rate bioretention media.
That creates more options when drainage area, right-of-way, utility conflicts, grading, parking requirements, or land value make traditional bioretention difficult to accommodate.
Key Points
- NJDEP-certified 85% TSS removal MTD
- Certified media infiltration rate of 400 inches per hour
- Recognized as green infrastructure under New Jersey stormwater rules
- Suitable for constrained, retrofit, streetscape, and infill applications
- Supported with design worksheets, drawings, specifications, and technical guidance
GIVE REVIEWERS DOCUMENTED PERFORMANCE, NOT JUST PRODUCT CLAIMS
A stormwater design is only as defensible as the assumptions behind it.
NJDEP certification provides third-party regulatory review of FocalPoint’s performance rather than relying solely on manufacturer-generated claims. For engineers, that means a clearly documented TSS removal rating and certified hydraulic loading rate that can support sizing, modeling, technical narratives, and agency discussions.
NJDEP approvals are also frequently viewed beyond New Jersey as an important benchmark when agencies, owners, and consulting firms evaluate stormwater technologies. While every jurisdiction retains its own approval requirements, the certification gives project teams a stronger technical foundation for discussing performance and suitability with reviewers.
Engineering Value
- More defensible design assumptions
- Greater confidence during product evaluation
- Clear performance documentation for reviewers and owners
- Reduced uncertainty during preliminary sizing
- A stronger basis for comparing treatment alternatives
HIGH-RATE TREATMENT WITHOUT ABANDONING GREEN INFRASTRUCTURE
FocalPoint uses physical, chemical, and biological treatment mechanisms associated with soil, plants, and microbial activity to provide pollutant removal consistent with biofiltration.
The difference is hydraulic efficiency.
Its high-rate engineered media allows civil engineers to achieve water-quality treatment within a much smaller footprint while retaining the functional and visual benefits of a planted system. FocalPoint may also be configured as part of a broader treatment train incorporating pretreatment, flow control, conveyance, storage, and downstream discharge components.

DESIGNED FOR THE CONSTRAINTS CIVIL ENGINEERS ACTUALLY FACE
Stormwater controls rarely receive unlimited space, ideal grades, or a blank site plan.
Civil engineers must coordinate drainage, utilities, parking, accessible routes, landscaping, structures, road geometry, maintenance access, and permitting requirements within the same footprint.
FocalPoint helps resolve those conflicts by concentrating biofiltration performance into a compact, modular system.
Its high-rate media can reduce the surface area needed for water-quality treatment, creating additional flexibility for:
- Tight rights-of-way
- Urban redevelopment
- Parking-lot retrofits
- Commercial and institutional sites
- Transportation corridors
- Municipal streetscapes
- Sites with utility or grading conflicts
- Projects where conventional bioretention consumes too much developable area
FocalPoint also integrates into complete stormwater treatment trains. Appropriate pretreatment can capture gross pollutants and sediment before runoff reaches the media, helping protect long-term infiltration performance and simplify maintenance.
FROM CONCEPT LAYOUT TO FINAL SPECIFICATION
FocalPoint is supported as an engineered system, not simply supplied as a media product.
Convergent Water Technologies and its local partners can assist civil engineers with preliminary sizing, layout development, inlet and outlet configuration, pretreatment selection, standard details, specifications, and maintenance planning.
That support helps project teams answer the practical questions that often determine whether a stormwater technology makes it onto the plans:
- How much treatment area is required?
- How does the system fit the available drainage layout?
- What pretreatment is appropriate?
- How should bypass flow be managed?
- How will the system be accessed and maintained?
- What details and specifications are available for the construction documents?
