Yes, stormwater harvesting systems can be successfully retrofitted in existing developments. Retrofitting involves integrating harvesting infrastructure into established urban or suburban areas. This can include adding catchment elements to rooftops, installing conveyance systems, and incorporating storage facilities.
While challenges like space limitations and existing infrastructure may require creative solutions, retrofitting enables communities to benefit from sustainable water practices without extensive redevelopment. It contributes to the resilience and adaptability of urban environments, promoting water conservation and reducing the environmental impact of stormwater runoff in established and growing communities.
