dc.description.abstract	Energy and water insecurities are global challenges, especially in arid and semi-arid regions. This paper proposes an optimal energy-water nexus management approach in residences using alternative energy and water resources, these alternatives are rainwater harvesting system, greywater recycling system, water storage, and gravity-fed distribution system. The Solving Constraint Integer Programming (SCIP) solver, in MATLAB’s OPTI toolbox, is used to solve the multi-objective optimization problem. Simulation results show that the optimal tank sizing and system operations will minimize the capital and operational cost of the system. The solver produced a potable water savings of 20.5% and an energy savings of 62.54%.	en_ZA
