How we helped
Castalia helped develop principles for sustainable and optimal use of water resources within Qatar’s National Development Strategy 2018-2022. To do this we forecast water demand based on population and economic growth projections, demonstrating the unsustainability of existing water management practices. We advised that, to optimize use of water resources, water from all sources should be treated as being as valuable as desalinated water (the marginal resource). This pointed to guiding principles such as maximizing use of recycled water (treated sewage effluent), promoting water efficiency in both urban and agriculture uses, and building a water reserve through aquifer recharge.
