RAFT

Runoff Attenuation & Filtration Technology

BIORETENTION MADE SIMPLE.

RAFT is a bioretention solution that marries simplicity, uniformity, and adaptability in a cost-effective package for urbanized and highly-constrained environments.

 

By offering a comprehensive solution for mitigating flooding and improving water quality in otherwise problematic spaces, InfraSGA can help communities solve their stormwater management issues without committing to massive stormwater system overhauls.

 

TWO-MINUTE SNAPSHOT

 

RESILIENT

RAFT is a solution that allows sites to respond to the increasing challenges of modern stormwater management, even under highly constrained conditions. For both storage and treatment needs, RAFT allows sites to maximize their responsiveness.

ADAPTABLE

Each system will include site-specific soil mixes and plant communities. The RAFT system will also be layperson-friendly, with visual aids and oral explanations that accompany technical documents. And with a flexible kit of parts, RAFT fits into a wide variety of site conditions.

FUNCTIONAL

RAFT simplifies complex assemblies and key functions into a “paint by numbers” modular approach, with standardized and replaceable components which dramatically reduce the need for custom design and engineering, while still achieving high-quality construction assembly and required ecosystem performance. 

TRANSFORMATIVE

RAFT provides substantial benefits to a wide variety of site conditions while maintaining cost competitiveness and manageability without sacrificing long-term performance and durability.

RAFT is...

STORMWATER FLOW

When a major storm event hits, RAFT provides the benefits of bioretention while conforming to constrained spaces. As RAFT collects accumulated runoff, it pre-treats it through a sediment/debris removal tray. A site and soil-specific plant community will then filter and retain the stormwater runoff, as well as remove potentially harmful nutrients while the accumulated runoff slowly infiltrates into the gravel and soil beneath it (or returns to the drainage system post-filtration through an underdrain connection). RAFT can also be connected to auxiliary storage features as shown to capture excess stormwater in more severe storm events.

 

IN THE NEWS

INFRASGA IS SELECTED AS A FINALIST IN $1.5M COASTAL COMMUNITY RESILIENCE CHALLENGE

InfraSGA is excited to be one of the six final winners of a RISE Resilience Innovation Fund offering more than $1 million in funding established with federal CDBG-DR funds for an Urban Retrofit Bio-Retention System. The RISE Resilience Challenge sought innovative solutions around major resilience issues that can be demonstrated in the Hampton Roads region of Southeastern Virginia, can be built into sustainable businesses, and are scalable to other communities. Challenge judges selected the seven finalists from a very competitive pool of 51 innovative solutions around five Challenge topics: water management, data analytics, buildings protection, critical systems functionality, and disconnected communities. RISE partnered with MIT Solve to attract submissions and judges from around the world.

RISE will work alongside InfraSGA to facilitate access to real-world infrastructure, data, experts and mentors we will need to build our solution into a successful businesses. Watch their video to learn more about RISE and the Hampton Roads living laboratory.

MEET THE WINNERS:

 

LIGONIER,PA

This custom-built bioretention brought an attractive and functional stormwater feature at an intimate scale. These flow-through planters were both innovative and educational in the continued development of the RAFT solution. While the finished product has proven effective, the custom design and construction required a substantial effort and skill to complete.
