Smart Technologies and Water Supply Planning II

Dear Colleagues,

Urbanisation, population growth and climate change drive the planning of water supply systems. Urban developments are facing a shortage of fresh water resources, yet somewhat perversely, an increase in their wastewater and stormwater generation; adverse impacts on the ecology of the receiving water environment; aging infrastructure; and financial constraints and increase in GHG emissions.

Smart technologies can play an important role in the better planning, design, implementation, operation and maintenance of water supply systems. These technologies may include application of geospatial technologies, including remote sensing; pressure-reducing systems to mitigate potable water mains pipe bursts; maintaining demand-driven pressure in systems; minimising non-revenue water through timely location of leaks; real-time monitoring of systems; application of IoT for water quantity and quality monitoring; use of ITC and control systems; real-time water network analysis for system control; management of rainwater storages for reducing peak runoff rates; and real-time feed back of water consumption and price to customers, alerting customers to hidden (sub surface) water leaks.

The application of smart technologies is also being promoted in water systems for the management of stormwater-harvesting systems; local aquifers to store stormwater (ASR); real-time detection of pathogens using chip-based DNA technology; critical control points to ensure “out of spec water” does not pass onto the next treatment step; and real-time sensors and alert systems for cross-connection in dual reticulation systems in suburbs and on-demand UV systems (i.e., LED-based) to reduce energy use from “under the sink” domestic installations.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
