Abstract

There is an increase in the development of water hydraulic systems that are connected to environmental sustainability, which demands designs that balance engineering performance and environmental responsibility. This paper presents ECO HYDRA, an innovative, environmentally conscious working model that optimizes hydraulic system design through multi-objective and sustainability-based analysis. The model incorporates fluid dynamic simulation and a stepwise expansion of the NSGA II evolutionary framework, incorporating eco-penalty considerations for carbon emissions, material consumption, and water quality degradation. In contrast to traditional hydraulic design methods, ECO HYDRA reduces energy usage, leaks, and environmental harm simultaneously, while maximizing the incorporation of renewable sources and enhancing the system's resilience to climate change. Evaluation metrics include ecological indicators, such as the lifecycle CO2 footprint, water conservation efficiency, and renewable utilization, which provide practical input into sustainable development. Urban water distribution and irrigation case studies, along with reductions of up to 20% in pumping energy, 15% in water losses, and 12% in embodied CO2 emissions, relative to baseline designs. By connecting the optimization of engineering with ecological performance, ECO-HYDRA has also provided a scaling route for designing water hydraulic systems that actively contribute to environmental protection and resource efficiency in current ecological engineering.
