The StormArc System, engineered and owned by GoodFlow Solutions, is a next-generation precast concrete stormwater retention and detention solution. The product is licensed to LHV Precast for production and distribution throughout New York State, Western Massachusetts, and Western Connecticut. StormArc delivers maximum liquid storage capacity, a smaller installation footprint, and requires less than 10% of the gravel needed for traditional systems resulting in significant savings in excavation, labor, and installation time.
With its HS-20 load rating, steel-reinforced precast concrete modules, and independently verified performance, StormArc addresses the evolving challenges of stormwater infrastructure with a durable and versatile solution.
Municipalities and civil engineers face increasing pressure to design stormwater systems that perform reliably under extreme weather, comply with environmental regulations, and reduce long-term maintenance costs. Many traditional systems rely heavily on gravel beds and complex header systems, limiting usable land area and increasing project costs.
The StormArc System was developed to address these challenges by optimizing hydraulic efficiency, reducing material requirements, and simplifying installation—while maintaining the structural integrity expected from modern civil engineering solutions.
StormArc is a steel-reinforced precast concrete retention and detention system designed for both new installations and retrofit environments. As a GoodFlow Solutions product licensed to LHV Precast, it brings proven engineering innovation to the Northeast region with production supported by LHV’s NPCA-certified manufacturing standards.
Each StormArc module spans 9’4” between rows and 4’ in running length, designed for installation without cranes or heavy lifting equipment. Overlapping lips prevent soil intrusion, while solid end caps create a protected, fully enclosed system.
StormArc is designed with a focus on longevity:
StormArc is suitable for a broad range of stormwater detention and retention applications, including:
StormArc supports sustainable site development practices by reducing gravel usage, minimizing excavation, and extending system lifecycle through durable precast construction. These efficiencies align with modern green infrastructure principles, and sustainable urban development, supporting both environmental and economic project goals.
The StormArc System is a licensed product from GoodFlow Solutions, produced by LHV Precast exclusively for:
All StormArc modules manufactured by LHV Precast are produced in an NPCA Certified Plant and adhere to ASTM standards for reinforced concrete, including ASTM C478 for strength and absorption testing.
StormArc provides a modern, engineered approach to stormwater detention and retention—integrating verified structural performance, installation efficiency, and long-term durability in a single modular system. As a licensed manufacturer for the Northeast, LHV Precast is proud to support engineers, municipalities, and contractors with a solution that reduces cost, increases flexibility, and delivers reliable results for decades.
LHV Precast, Inc. is a trusted manufacturer of certified precast infrastructure solutions serving New York State, Massachusetts, and Western Connecticut.
