The broader/commercial potential of this I-Corps project is that it provides a cost-effective, low-impact hybrid 'green' approach for addressing stormwater runoff, one of the leading causes of impairment to our nation's waters. These runoff problems are expected to be exacerbated, particularly in urban areas, as a result of the coupled impacts of future population growth-driven land use and cover changes and storm events associated with projected climate change. Recognition of these threats to our water resources, together with the increasing costs of conventional municipal water treatment, has led to interest in green infrastructure approaches for stormwater management. However, in their current design, many of these green infrastructure systems are passive: their effectiveness for intercepting water and removing pollutants is highly variable. The technology described here will provide stormwater engineers, developers, city managers, and homeowners with important design criteria that will maximize green infrastructure performance and functionality. The commercialization of this hybrid green technology is therefore key for making it widely accessible to potential end-users to address both present and future stormwater/water resource challenges.This I-Corps project will assess the market potential and commercialization feasibility of a modular, hybrid stormwater management technology that augments green infrastructure both to maximize pollutant removal efficiency and allow for water storage. The modular hybrid green infrastructure (MHGI) is a sealed system with a specialized pipe and valve assembly that allows for both the control of water retention times as well as the location of the subsurface water table height, so that intercepted stormwater can be held within the soil matrix at a depth to maximize aerobic/anaerobic conditions that promote bioremediation via plant and microbial processing. Stormwater storage times can be controlled and the system can be made operational to adjust for changes in historical or projected runoff volumes. The intercepted water can also be stored within the system, pending removal by evapotranspiration, or for reuse purposes such as irrigation. Preliminary alpha testing of this technology demonstrated significant and consistent nitrogen and phosphorus removal efficiencies with 88% nitrate and 100% phosphate removal observed for urban runoff, 95% total nitrogen and 81% phosphate removal observed for septic effluent, and 50% nitrate, 71% ammonium, and 55% removal observed for agricultural runoff.

这个I-Corps项目的更广泛/商业潜力是，它为解决雨水径流提供了一种经济高效的，低影响的混合“绿色”方法，这是造成国家水域损害的主要原因之一。由于未来人口增长驱动的土地利用以及与预计的气候变化相关的变化和风暴事件的耦合，预计这些径流问题将加剧，尤其是在城市地区，尤其是在城市地区。认识到对我们的水资源的这些威胁，以及常规市政水处理的越来越多的成本，引起了人们对雨水管理的绿色基础设施方法的兴趣。 但是，在目前的设计中，许多这些绿色基础设施系统都是被动的：它们拦截水和去除污染物的有效性是高度可变的。 此处描述的技术将为雨水工程师，开发人员，城市经理和房主提供重要的设计标准，以最大程度地提高绿色基础设施性能和功能。 因此，这种混合绿色技术的商业化是使潜在的最终用户可以广泛使用的关键，以应对现在和未来的雨水/水资源挑战。该I-Corps项目将评估模块化的，混合雨水管理技术的市场潜在和商业化的可行性，以增强绿色基础设施，以增强绿色的基础设施，从而最大程度地提高污染物的水位储存效率。 模块化杂交绿色基础设施（MHGI）是一个密封系统，具有专门的管道和阀组件，既可以控制水保留时间以及地下地下地下地下水位高度的位置，因此可以将截距的雨水保持在土壤基质中的深度中，以最大程度地促进a anaerobic Cresential Bervertiation Beryobic Corner ander Biobemediation。可以控制雨水存储时间，并且可以使系统进行操作以调整历史或预计径流量的变化。截取的水也可以存储在系统中，以蒸散量或出于灌溉目的（例如灌溉目的）进行清除。 该技术的初步α检测表明，在城市径流中观察到的氮和88％硝酸盐和100％磷酸盐的去除效率显着且一致，总氮和81％磷酸盐去除的95％磷酸盐去除败血症，磷酸盐的去除率，用于败血症，50％硝酸盐和55％ammon和55％的脂肪。
