Yes, the roofing design can integrate rainwater collection systems for indoor non-potable uses. In fact, many modern roofing systems are designed to include rainwater harvesting as a sustainable water management solution. The roofing design can incorporate features such as gutters, downspouts, and filtration systems that allow rainwater to be collected and stored for later use in non-potable applications like toilet flushing, irrigation, and industrial uses. These systems can help reduce dependency on freshwater sources and promote water conservation. It's important, however, to ensure that the collected rainwater is properly treated and filtered before using it for non-potable purposes.
