While stormwater harvesting is scalable, certain limitations must be considered. The feasibility and effectiveness of larger projects may be influenced by the availability of suitable catchment areas and the complexity of conveyance systems. Adequate space for storage facilities is essential, and increased scale may necessitate substantial upfront costs.
The management of water quality becomes more challenging with larger volumes, requiring sophisticated filtration and treatment methods. Community acceptance and local regulations may also impact the scalability of projects. Despite these considerations, innovative technologies and strategic planning continue to address scalability challenges, making stormwater harvesting a viable and scalable solution for sustainable water management.
