Abstract New forms of decentralized water infrastructure with digital projects driven by private investment are being introduced in low-income urban neighborhoods the global south aim increasing coverage affordable and safe water. These ‘smart’ water-vending machines gaining popularity to meet demand growing cities as they low-cost, transparent, revenue generating replicable. However, field evi...

This paper describes the application of using a submersible remotely operated vehicle (ROV) to map and explore underground water cisterns during a series of expeditions to Malta and Gozo. The purpose of this project was to create maps of ancient cisterns located under private homes, churches, and fortresses where passageways leading to the cisterns are too narrow and dangerous for humans to ent...

Water is one if not the controlling factor of regional development around the Mediterranean, and its political importance can hardly be exaggerated. While water budgets, supply and demand balances are in principle straight forward mass budget problems and amenable to quantitative analysis, the socio-economic framework that ultimately drives the water resources management introduces another laye...

A transcritical heat pump (THP) cycle using carbon dioxide (CO2) as the refrigerant is known to feature an excellent coefficient of performance (COP) as a thermodynamic system. Using this feature, we are designing and building a system that combines a water-to-water CO2 heat pump with both hot and cold thermal storages know as Thermal Battery (TB) (Blarke, 2012). Smart and effective use of inte...

How can we make sustainable urban drainage systems (SUDS) smart? SUDS help us to manage surface water runoff from urban environments but they are capable of delivering much more. This paper looks beyond the water quantity and quality improvement functions of SUDS and investigates the multiple benefits that can be gained by implementing smart SUDS solutions. This work provides a new perspective,...

Shrinking water resources all over the world and increasing costs of water consumption have prompted water users and distribution companies to come up with water conserving strategies. We have proposed an energy-efficient smart water monitoring application in [1], using low power RFIDs. In the home environment, there exist many primary interferences within a room, such as cell-phones, Bluetooth...

Residential households have the potential to conserve water, especially in behaviourally influenced end uses such as showering. Visual display monitors detailing shower water consumption parameters provide householders with a better understanding of their water use consumption and serve as a prompt to conserve. This longitudinal study first applied high resolution smart meters to create a regis...

Abstract This paper presents a comprehensive water quality monitoring system that employs a smart network management, nano-enriched sensing framework, and intelligent and efficient data analysis and forwarding protocols for smart and system-aware decision making. The presented system comprises two main subsystems, a data sensing and forwarding subsystem (DSFS), and Operation Management Subsyste...

The smart water infrastructures laboratory is a research facility at Aalborg University, Denmark. enables experimental in control and management of realistic environment. designed as modular system that can be configured to adapt the test-bed desired network. recreated this are district heating, drinking supply, waste collection systems. This paper focuses on first two types infrastructure. In ...
