The document discusses smart urban water grids as a solution to water stress in cities. It proposes integrating systems like rainwater catchment, water reuse from households and industries, and floating water treatment to create a more sustainable water system. Examples are given of projects implementing aspects of smart grids, like rainproof buildings that store rainwater and rooftop farms. The goal is to move toward water-autarkic or self-sufficient cities through circular water management approaches.

- 14. Floating Water Treatment Cascade The development of modular flexible constructs on demand can relief the socio- economic pressure that results from climate change, population growth and increasing urbanization. More specifically, the Floating Water Treatment Cascade contributes to water security and to a circular and bio-based economy by preventing the waste of fresh water and the waste of raw materials.

- 26. WHO Drinking water guidelines 6.2 Rainwater harvesting • Rainwater harvesting is widely practiced at a household level but is increasingly being used on a larger community scale. Rainwater can provide an important source of drinking-water in some circumstances as well as a useful source of water for blending with other sources to reduce the levels of contaminants of health concern, such as arsenic and fluoride. • The development of formal WSPs at the household level may not always be practical, but promotion of sanitary inspection with simple good practice is important. • Well-designed rainwater harvesting systems with clean catchments, covered cisterns and storage tanks, and treatment, as appropriate, supported by good hygiene at point of use, can offer drinking-water with very low health risk. • Further treatment at the point of consumption may be applied to ensure better quality of drinking-water and reduce health risk. Solar water disinfection and point of use chlorination are examples of low-cost disinfection options for the treatment of stored rainwater. These and other household water treatment technologies are discussed in more detail in sections 7.3.2 (microbial) and 8.4.4 (chemical). 7-3-2016 SUWG 26

BUIKSLOTERHAM IS RAINPROOF AND HAS RESOURCE RECOVERY FROM WASTE WATER Circulair Buiksloterham • All rainwater is managed above ground with the capacity to handle heavy peak rainfall without flooding or nuisance; Buiksloterham is a “rainproof” part of the city • Domestic & commercial water demand is reduced by 25% • Different quality levels of water are matched to different end uses: drinking water is used intelligently for only high quality functions • Wastewater is mostly source separated; heavily polluted water is not mixed with lightly polluted water (ideally, yellow and black water are collected separately) • Most of the total nutrients and other resources from wastewater are recovered in usable form with a target of full recovery; heat should be recovered from wastewater where possible & sensible • Most of the micro pollutants from wastewater are fully removed

Editor's Notes
- The mobile dyke is designed with a 3 component safety system. First the dyke body or tube, this contains the water. Second, the patented net, this net ensures the dyke’s stability and makes sure the different dyke modules are connected to form a chain. And third and last the sealing membrane, this is the final sealing for water and an important part to prevent piping. By the seperation of the dike body, net and sealing membrane the dyke has a high safety reserve.
- The mobile dyke is usable on almost every surface. From gravel to sand, paving stones, asphalt, concrete, grass and even water. It is possible to set up a mobile dyke in flowing water, when you fill the dyke directly when rolling out, the dyke becomes heavy and will stay on its place.
