Comparative Evaluation of Automation Concepts for Water Industry Systems

This white paper presents a comparative evaluation of automation concepts specifically tailored for water industry systems, focusing on optimizing life cycle costs (LCC) and energy efficiency. It outlines the significant challenges faced in energy efficiency and cost optimization within water and wastewater treatment plants. The document discusses various tools and methodologies for assessing LCC of alternative technologies, emphasizing the importance of considering not only initial investment costs but also long-term operational costs. It highlights the potential for energy efficiency improvements through the use of advanced automation systems and energy-efficient components. The paper also details a user-friendly Excel-based tool developed by ZVEI and Deloitte, designed to assist in evaluating different technologies based on their energy efficiency and LCC over the entire life cycle. Furthermore, it provides a case study of the Böblingen-Sindelfingen wastewater treatment plant, illustrating practical applications of these concepts and the benefits realized from modernization efforts.
