Some of the impacts of climate changes could affect human health, food security, water
resources, and ecosystems. Both water supply and wastewater disposal require a lot of energy.
The collection, transport, and finally, treating water till be capable of using drinking purposes
consume massive amounts of energy, leading to releasing huge amounts of carbon dioxide per
annum. A better design of these water infrastructure systems could no doubt achieve
substantial energy savings through reducing emissions at a reasonable cost. This research
investigates the alternatives for designing such water distribution systems considering CO 2
emissions and costs together as objectives. The trade-offs between these three parameters are
investigated to perform optimal water network. For understanding these trade-offs, a multi-
objective GA optimization module was created.
