As stormwater requirements become more demanding and available land becomes more valuable, engineers, developers, contractors, and municipalities need water management systems that do more than meet minimum specifications. They need solutions that are strong, efficient, flexible, and practical to install.
That is where StormArc® stands apart.
StormArc®, a next-generation precast concrete stormwater retention and detention system licensed from GoodFlow Solutions and produced by LHV Precast, delivers superior performance, efficient installation, and unmatched engineering flexibility. Built for residential, commercial, industrial, and municipal applications, StormArc® helps project teams solve difficult site challenges while preserving more usable land for buildings, parking areas, driveways, green space, utilities, or future development.
Traditional stormwater detention systems can require large excavation areas, extensive materials, complex layouts, and significant installation logistics. On space-constrained properties, those requirements can limit what can be built, expanded, or preserved.
StormArc® was developed to solve those problems.
The system uses durable precast concrete chambers designed to maximize water storage while reducing the overall footprint required for retention or detention. By storing more water per square foot, StormArc® helps engineers and developers meet stormwater management requirements without sacrificing valuable site area.
For properties where every square foot matters, that can make a meaningful difference.
One of StormArc®’s greatest advantages is its simple modular design. The system is built using two primary components, allowing crews to repeat the same installation steps throughout the project. There are no specialty pieces, no complicated connectors, and no special fasteners required.
This makes StormArc® highly adaptable to a wide range of project layouts and site requirements. Much like a building block system, StormArc® can be configured to fit the specific storage volume, footprint, and design needs of each job.
System heights can range from approximately 2 feet to 13.5 feet, giving engineers and contractors added flexibility when designing around site constraints, elevation requirements, parking areas, access roads, and other development priorities.
StormArc® is designed with jobsite practicality in mind. Unlike some large precast or underground stormwater systems, StormArc® components can be set using medium-sized excavation equipment.
That means no crane is required for installation.
For contractors, this can simplify logistics, reduce equipment demands, and make installation more manageable on tight or complex jobsites. For developers and project owners, it can help support a more efficient construction process from excavation through completion.
StormArc® is manufactured using 5,000 PSI concrete with reinforced steel, creating a strong precast system engineered for long-term performance. The system is HS-20 rated with 6 inches of cover, making it suitable for applications where structural durability is essential.
This level of strength allows StormArc® to be used beneath hardscape surfaces such as driveways, parking lots, and other load-bearing areas. Rather than forcing stormwater infrastructure into undeveloped or unusable corners of a site, StormArc® gives project teams more flexibility in how land is planned and used.
The arched chamber design is central to StormArc®’s performance. The arcs are what allow the system to achieve impressive storage capacity while making efficient use of available space.
This design advantage is especially important for projects where stormwater requirements are high, but available land is limited. By reducing the amount of land dedicated solely to water management infrastructure, StormArc® can help preserve more usable property for development, access, hardscape, or green space.
For engineers, developers, and property owners, that means StormArc® is not just a stormwater product. It is a land-use solution.
The practical thinking behind StormArc® is closely tied to the experience and innovation of Frank Currivan, creator of the patented CTL system and a third-generation leader in his family’s septic and drainage business.
Frank grew up around the challenges created by traditional pipe and gravel trench systems. As homes became larger, water usage increased, and real estate values continued to rise, he saw a growing need for systems that could provide greater capacity in a smaller footprint. Landowners did not want septic or drainage infrastructure preventing them from expanding a home, adding a pool, building a deck, or making full use of their property.
With more than 30 years of hands-on experience designing and solving difficult septic and drainage challenges, Frank developed durable concrete chamber technology that addressed those needs. His patented designs helped create systems that could solve difficult site problems, preserve land value, and provide reliable long-term performance.
Over time, Frank became known as a regional problem solver for challenging or “impossible” septic and drainage requirements. His work has supported successful installations across New England and beyond, from residential developments and lake homes to office buildings and coastal properties.
Today, Frank continues to support the growth of GoodFlow Solutions, helping bring practical, field-tested water management technology to residential, commercial, and industrial projects across the U.S.
