Conclusion
How can decentralized stormwater management technologies be utilized in northeast Güzelyurt to effectively address the risk of regular urban flooding?
Septic Tanks & Dry Wells
-Septic Tanks-Bio swales-Cisterns
Existing infrastructure and decentralized stormwater management technologies can be effectively utilized, while taking water scarcity and stakeholder needs into account within the context of environmental justice and resource efficiency, to address urban flooding in north-east Güzelyurt
