Workshop: To centralize or decentralize wastewater treatment

Join us for a workshop exploring the opportunities and limitations of centralized and decentralized Wastewater treatment. Conventional sewerage planning approach emphasizes centralized wastewater treatment plants, requiring long-distance transport of wastewater for economies of scale and resource recovery. However, this requires extensive infrastructure and maintenance, consuming significant energy and resources, contributing up to 80% of the project cost. In contrast, decentralized treatment systems offer treatment near the source, enabling convenient and cost-effective water reuse, thus enhancing sustainability and resilience. The workshop aims to: Explore challenges and benefits of centralized and decentralized treatment systems from diverse stakeholder perspectives. Discuss Danish case studies comparing centralized and decentralized systems, emphasizing case-specific assessments. Identify tools for holistic decision-making and development needs to enhance sustainable and cost-efficient wastewater infrastructure. Participating in the workshop is a unique opportunity for you to engage in discussions and widen your horizon gaining new perspectives on wastewater treatment from both an Indian & Danish context.
