Leading the Industry for Groundwater Recharge and Urban Infrastructure with MaxWell® Stormwater Infiltration System
In today’s rapidly changing world, the need for sustainable stormwater management and groundwater recharge has never been more urgent.
Cities and suburbs alike are facing the environmental consequences of aging infrastructure and stricter water regulations.
At Oldcastle Infrastructure, we believe that effective solutions must do more than meet technical requirements—they must also support long-term environmental resilience and community well-being.
That’s why we developed the MaxWell® Stormwater Infiltration System. More than just a drywell, MaxWell® represents a forward-thinking approach to groundwater recharge, combining proven performance with scalable design and expert support.
Whether you’re planning a new development or retrofitting an existing site, MaxWell® offers a reliable, cost-effective way to manage runoff, restore natural hydrologic cycles, and contribute to healthier ecosystems.
What is MaxWell®?
Developed by Torrent Resources, MaxWell® is Oldcastle Infrastructure’s subsurface stormwater infiltration system engineered to manage runoff by allowing water to percolate into the ground, replenishing aquifers and reducing surface discharge. With over 70,000 systems installed since 1974, MaxWell® is a proven, effective drywell solution, and our expert teams take care of design and installation—helping contractors to save time, reduce costs, and improve safety on site.
Why was MaxWell® developed?
We developed MaxWell® in response to the growing demand for sustainable stormwater management in urban and suburban environments. With increasing impervious surfaces and tightening regulations, traditional systems often fall short. MaxWell® offers a scalable, cost-effective, and high-performance alternative that integrates seamlessly into modern infrastructure.
How is MaxWell® engineered to perform across different site conditions and long-term use?
MaxWell® units are built using high-strength precast concrete, ensuring durability and long service lifetimes of over 50 years. The system is designed to accommodate varying infiltration rates, soil types, and water table depths—making it ideal for applications focused on groundwater recharge, flood mitigation, and water quality improvement.
In what ways does MaxWell® support environmental sustainability and community values?
MaxWell® contributes to broader environmental goals by promoting infiltration, restornig natural hydrologic cycles and supporting healthier ecosystems. It’s a product that not only solves engineering challenges but also aligns with community values and long-term sustainability objectives.
