Masdar City’s water needs are less than half that of business as usual (BAU). In Phase 1 it is targeting consumption of 180ltr/person/day, well below the 550ltr/p/d BAU. The city’s target will be progressively lowered, to an ultimate goal at full build-out that is 40% below the Phase 1 target. However, this does not include water required for district cooling, which could double the amount of water required by the city.
To achieve these lower consumption figures, the city is using a broad array of water-use reduction technologies and systems. Highly efficient fittings, fixtures and appliances, smart water metres that inform consumers of their consumption, and smart metres to identify leakage across the system are already in use. As the city pursues more ambitious consumption targets, additional strategies will be implemented, including a water tariff to promote further water efficiencies.
As well, treated wastewater is 100% recycled for use in landscaping, which has achieved a 60% reduction in water usage per square metre over BAU, through a variety of strategies, including highly efficient micro-irrigation, landscaping design that minimises plant evapotranspiration, and low-water-use and indigenous plants and trees.
