Accessing the Colorado State Revolving Fund

Rainwater harvesting entails the collection and storage of rainwater for future use from rooftops and other impervious surfaces, reducing demand on municipal water supplies and mitigating stormwater runoff. Harvesting projects typically involve installation of collection systems, storage tanks, and distribution mechanisms to utilize harvested rainwater for non-potable applications such as landscape irrigation, industrial processes, or toilet flushing. By decreasing reliance on traditional water supplies, rainwater harvesting helps alleviate stress on municipal systems while promoting water conservation and sustainability.

Graywater refers to “soapy” wastewater from (non-kitchen) sinks, showers, and laundry facilities (in contrast to “blackwater,” which refers to wastewater from toilets, dishwaters, and urinals). Reusing graywater involves treating and redirecting it for non-potable purposes, thereby reducing the demand for potable water and decreasing the volume of wastewater requiring treatment. Eligible graywater reuse projects may include the development of collection and treatment systems that allow for the safe application of graywater in landscape irrigation, toilet flushing, or other appropriate uses.

Onsite reuse systems involve the collection, treatment, and reuse of water directly at the location where it is generated, such as in individual buildings or facilities. These systems can manage various water sources, including graywater and stormwater, treating them for non-potable applications like toilet flushing, cooling systems, or landscape irrigation. Implementing onsite reuse systems reduces the demand on centralized water infrastructure, conserves potable water resources, and enhances overall water resilience. Projects may include the installation of advanced treatment technologies, storage facilities, and distribution networks tailored to specific site needs. By decentralizing water management, onsite reuse systems offer flexible and sustainable solutions that can be customized to local conditions.
