High-Performance Modular Biofiltration Systems

 

Why FocalPoint? The Proof is in the Performance!

focalpoint-gallery-sidebar-graphic-2Treat the same amount of water in <5% of the area required by traditional bioretention. By decreasing a property’s surface storage volume requirements using FocalPoint, you can:

  • Develop more
  • Spend less
  • Improve Aesthetics

FocalPoint utilizes physical, chemical and biological mechanisms of a soil, plant and microbe complex to achieve pollutant removal rates consistent with traditional bioretention, and the option of increased removal characteristics for specific pollutant targets.

The Economics

focalpoint-gallery-sidebar-graphic-8Although the price per square foot of FocalPoint is many times higher than traditional bioretention, the efficiency of the FocalPoint High Performance Media makes the system more than 30 times smaller, per acre treated, resulting in a 50% cost savings per acre treated. The first year’s maintenance is included in all FocalPoint HPMBS installations to ensure that the system is given the best opportunity to succeed, and low cost annual maintenance contracts are available.

The Economics in Action

focalpoint-gallery-sidebar-graphic-11When 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 land, property owners can increase long-term revenue and/or property value. In the example, the use of FocalPoint vastly increased both the short and long term economics of this apartment complex - allowing for 10 buildings rather than the 8 in the original non-LID approach. 

Increase Property Aesthetics

focalpoint-gallery-sidebar-graphic-10Those in the industry know how difficult it is to find an attractive detention pond. All too often detention ponds are placed out of sight and forgotten about, left to become over-grown eyesores. However, using FocalPoint, there are unlimited beautification opportunities.  With only occasional cleaning required to remove any large undesirables caught in the top mulch layer, FocalPoint and its surrounding landscape can create an asset to a property, such as an attractive green space space or rain garden.

Maintenance In Mind – Simple & Cost Effective

The first year’s maintenance is included in all FocalPoint HPMBS installations to ensure that the system is given the best opportunity to succeed, and low cost annual maintenance contracts are available.

The potential failure for most LID/GI BMP’s is highest within the first year and success or failure is often dependent on whether the system is being properly inspected and maintained. Construction EcoServices’ commitment to system success doesn’t stop when the installation is complete.

More Details

FocalPoint High-Performance Modular Biofiltration System (HPMBS) is a scalable biofiltration system which combines the efficiency of high flow rate engineered soils with the durability and modularity of a highly pervious expandable underdrain/storage/infiltration system. The modular FocalPoint HPMBS is a complete, integrated system with a demanding specification that insures functionality, performance and maintainability. With rigorous quality assurance standards and post-construction in-situ performance verification, FocalPoint HPMBS provides guaranteed performance.

The FocalPoint’s modular underdrain, unlike a traditional perforated pipe, not only supports the flow rate of the media, but can be expanded beyond the footprint of the media bed to provide unlimited underground detention, infiltration and/or storage for water reuse/infiltration.

FocalPoint HPMBS gives designers maximum flexibility in meeting both water quality and volume requirements.

The system can be used in combination with traditional LID BMPs such as grassy swales and vegetated depressions. It enables implementation of green streets using urban sidewalk planters; which because of the small footprint can support designs with large trees. These systems are also used for downspout planters, replacing underground treatment systems and are an easy retrofit for failed traditional bioretention systems. FocalPoint provides unlimited application opportunities for new construction and redevelopment.

In addition, 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 lot yield. Subsequently, more land can be developed, increasing long-term revenue and property value.

Although the price per square foot of FocalPoint is many times higher than traditional bioretention, the efficiency of the FocalPoint High Performance Media makes the system more than 30 times smaller, per acre treated, resulting in a 50% cost savings per acre treated. The first year’s maintenance is included in all FocalPoint HPMBS installations to ensure that the system is given the best opportunity to succeed, and low cost annual maintenance contracts are available.

Due to the efficiency of the FocalPoint media, scale is in its favor. Fulfilling equal requirements, a FocalPoint solution will use 30x less space than a detention pond solution

‘Cap & Seal’ Protection During Ongoing Construction Activity

Protecting the FocalPoint HPMBS during construction is of the utmost importance. The ‘Cap & Seal’ protection ensures a viable system regardless of the construction sequencing by sealing off the media bed until the contributing drainage area is stabilized. Solving this problem removes one of the most problematic issues in bioretention. Due to it’s small scale, FocalPoint HPMBS can be capped and sealed, allowing installation to take place early in the project construction cycle when other site utilities are installed.

We guarantee post-construction performance and we make sure your client gets it.

Performance Guaranteed with Post-Installation Verification

This hydraulic conductivity test procedure measures the entire media profile under saturated conditions to produce a reliable and accurate result.

To ensure the highest level of effectiveness, Convergent specifies that the FocalPoint HPMBS be tested within 90 days of commissioning, but no more than 270 days and we recommend the system be tested annually thereafter to provide ongoing quality assurance.
