This strategy, combined with water-efficient fittings and real-time monitoring, significantly reduces potable water demand and operating costs. In 2017, the CCUS consumed 0.18kl of potable water per annum per m2 of Gross Build Area (GBA), compared to 1.09kl per annum per m2 in a comparable development without these resilience measures.
