Water scarcity and ineffective water utilisation in agriculture provide considerable obstacles to global
food security and environmental sustainability. This study investigates the amalgamation of wastewater treatment
and IoT-enabled automated irrigation systems as pioneering approaches for sustainable water management in
agriculture. Farmers can diminish reliance on freshwater by treating and reusing wastewater, while IoT-enabled
irrigation systems enhance water utilisation via real-time monitoring, data analysis, and precise control. This study
assesses the technical, economic, and environmental advantages of integrating various technologies, emphasising
their capacity to improve water efficiency, crop productivity, and resource conservation. Case studies and
experimental findings illustrate the efficacy of IoT-enabled devices in minimising water waste and enhancing
irrigation scheduling. The report also examines the obstacles to using these technologies, including as expenses,
infrastructure, and farmer uptake. The results highlight the revolutionary potential of combining wastewater
treatment with IoT-based irrigation to attain sustainable agricultural practices, enhance water conservation, and
facilitate the shift towards a circular economy in agriculture. This study offers practical insights for policymakers,
agricultural stakeholders, and technology developers to further scalable and sustainable water management
strategies.
