distribution, and storage systems, including replacement of lead service lines. With respect to <br />clean water and wastewater infrastructure, the interim final rule provided that recipients may use <br />SLFRF funds to construct publicly owned treatment infrastructure, manage and treat stormwater <br />or subsurface drainage water, and facilitate water reuse, among other uses. Consistent with the <br />DWSRF and the CWSRF, the interim final rule provided that SLFRF funds may be used for <br />cybersecurity needs to protect water or sewer infrastructure, such as developing effective <br />cybersecurity practices and measures at drinking water systems and publicly owned treatment <br />works. <br />Use of DWSRF and CWSRF to Support Climate Change Adaptations. Many of the types <br />of projects eligible under either the DWSRF or CWSRF also support efforts to address climate <br />change. For example, by taking steps to manage potential sources of pollution and preventing <br />these sources from reaching sources of drinking water, projects eligible under the DWSRF and <br />CWSRF may reduce energy required to treat drinking water. Similarly, projects eligible under <br />the DWSRF and CWSRF include measures to conserve and reuse water, for example through <br />projects to reuse or recycle wastewater, stormwater, or subsurface drainage water. Treasury <br />encourages recipients to consider green infrastructure investments and projects to improve <br />resilience to the effects of climate change. For example, more frequent and extreme precipitation <br />events combined with construction and development trends have led to increased instances of <br />stormwater runoff, water pollution, and flooding. Green infrastructure projects that support <br />stormwater system resiliency could include bioretention basins that provide water storage and <br />filtration benefits, and green streets, where vegetation, soil, and engineered systems are <br />combined to direct and filter rainwater from impervious surfaces.
