Underground Detention Systems


Versatile solutions to solve many problems

Like any other investment into your property, a return on that investment needs to be understood. At Greenrise, we understand that and focus our efforts in consulting our clients around that return. Rainwater harvesting is no different. The common misconception is that a rainwater harvesting systems return on investment is in excess of twenty years. While this can be true, we have found that does not have to be the case. A basic understanding of how the supply and demand of rainwater harvesting works and looking at daily historical rainfall data, you can very easily drive the return on investment to 5 to 10 years. Adding a consistent supply of reclaimed water like condensate, can further drive the ROI into the single digits.

What We Do

Our drive to find the most costeffective and regionally-specific water and soil storage solution is driven by our extensive turnkey experience. We want to exceed your goals from conceptual design through material supply and installation. Our multifunctional designs routinely incorporate bioretention, permeable pavers, and other enhancements to maximize storage without unnecessary expenses.

Why Do We Recommend This Product?

“As a designer, I am looking for versatile solutions to solve many problems. R-Tank is that solution, especially for urban redevelopment, areas with high density and campus projects where space is limited and you never know what might be underground. The R-Tank’s modular flexibility gives me ample design flexibility, and gives our field crews the ability to make incremental adjustments in the field without any construction delays. The system is also strong, with options capable of supporting a fire truck with only 12” of cover.”

Greenrise was created from a drive to not only bring solutions for erosion and sediment control, and stormwater runoff treatment, but to do it with the best products like certified bioretention soil and proven erosion solutions, and services like SWPPP management and vegetated roof design. This was our goal from the start, and it is still what pushes us forward every day.
