Sewer Water Harvesting to Support Urban Green Spaces: The potential of ‘waste’ water as a resource to support urban green spaces during dry periods through integrated local water treatment

This research has investigated how Sewer Water Harvesting (SWH) can be applied to provide a climate-proof fresh water source to support Urban Green Spaces (UGS) in Amsterdam. SWH is the process of extracting raw municipal sewage from the sewer and locally treating this to provide fit-for-purpose water in a dense urban environment while treatment...

Confined Water Cluster Formation in Water Harvesting by Metal–Organic Frameworks: CAU-10-H versus CAU-10-CH₃

Several metal–organic frameworks (MOFs) excel in harvesting water from the air or as heat pumps as they show a steep increase in water uptake at 10–30 % relative humidity (RH%). A precise understanding of which structural characteristics govern such behavior is lacking. Herein, CAU-10-H and CAU-10-CH₃ are studied with -H, -CH<sub>3...

Water Adsorption in MOFs: Structures and Applications

Metal–organic frameworks (MOFs) are superior sorbents for water adsorption-based applications. The unique step-like water isotherm at a MOF-specific relative pressure allows easy loading and regeneration over a small range of temperature and pressure conditions. With good hydrothermal stability and cyclic durability, it stands out over...

The role of emergent and developing countries in the 21st century: A vision for sustainable housing development in Benin

At the same time that we’re solving climate change, we are building cities for another 3 billion people until 2050. That’s a doubling of the urban environment. The most extensive of this construction, and especially housing projects for the coming decades, will take place in emergent and developing countries. We, as architects, engineers,...

Sand dams for sustainable water management: Challenges and future opportunities

Sand dams are impermeable water harvesting structures built to collect and store water within the volume of sediments transported by ephemeral rivers. The artificial sandy aquifer created by the sand dam reduces evaporation losses relative to surface water storage in traditional dams. Recent years have seen a renaissance of studies on sand dams...

Water-catcher: A 3d-printed building component to mitigate water stress in developing countries

Urban population growth predictions and the threats posed by climate change will exacerbate social problems such as equal access to water worldwide. This will happen mostly in developing countries and will couple with other environmental issues such as the intensive use of raw materials and the production of new waste. New solutions need to be...

Mitigation plan and water harvesting of flashflood in arid rural communities using modelling approach: A case study in Afouna village, Egypt

This paper aims to propose methods to mitigate the risks of flash flood events in arid rural communities with poor infrastructure. A flash flood management case study was conducted at Afouna Village in Egypt, which is characterized by an arid climate and faced a devasting flash flood in 2015. First, the flash flood was modelled and it was...

Re-connecting with water: Creating spatial solutions for water collection and storage in rural areas of Morocco which suffer from water scarcity and loss of social and environmental cohesion

It is widely known that by 2050 the average temperature is going to increase by 2-3 °C while the precipitation is going to decrease 10-20 % in the North African region. The countries in this area have always been experiencing drought periods but due to the climatic changes, but, these periods are becoming more extreme leaving the population...

Gathering through water integration: Integrating water and its natural cycles in a hotel building design for 'Het Marineterrein' in Amsterdam

During the Paris climate conference in December 2015, 195 different countries recognized the dangers of climate change. One of the key points on which the participants of this conference agreed on was that cities should built resilience against the effects of climate change. The changing climate has amongst others major consequences for water...

Sustainable Dala: Showcase of a sustainable water infrastructure

The goal of this project is to develop a design for Dala’s water system that deals with challenges of the township in a sustainable way. Dala is a township of Yangon, Myanmar’s economic centre. It is located directly South of the central business district (CBD), across the Yangon river. The area is now largely underdeveloped, but in 2021 it will...

Evaluation of water harvesting and managed aquifer recharge potential in Upper Fara'basin in Palestine: Comparing MYWAS and water productivity approaches

The Upper Wadi Fara' basin, located at the West Bank, Palestine, has an average annual rainfall of 500 mm, which occurs only during winter. Agriculture uses stored soil water and complimentary irrigation from groundwater. Water harvesting (WH) and managed aquifer recharge (MAR) therefore is essential for sustainable water resources management in...
