“…Apart from its economic impact, it is often discussed as a priority for preserving water as a valuable commodity and to ensure sustainable use for the near and long term future, but also for regions with limited water access [3]. On the other hand, monitoring and control of quality is very diverse and includes chemical analysis as well as the detection of events and operational parameters that affect quality, such as turbidity, flow and backflow [2,[31][32][33][34][35][36][37][38][39][40][41][42][43][44]. It also includes reservoir stations such as stormwater retentions ponds [45].…”

Abstract-Sensor installation on water infrastructure is challenging due to requirements for service interruption, specialised personnel, regulations and reliability as well as the resultant high costs. Here, a minimally invasive installation method is introduced based on hot-tapping and immersion of a sensor probe. A modular architecture is developed that enables the use of interchangeable multi-sensor probes, non-specialist installation and servicing, low-power operation and configurable sensing and connectivity. A prototype implementation with a temperature, pressure, conductivity and flow multi-sensor probe is presented and tested on an evaluation rig. This paper demonstrates simple installation, reliable and accurate sensing capability as well as remote data acquisition. The demonstrated minimally invasive multi-sensor probes provide an opportunity for the deployment of water quality sensors that typically require immersion such as pH and spectroscopic composition analysis. This design allows dynamic deployment on existing water infrastructure with expandable sensing capability and minimal interruption, which can be key to addressing important sensing parameters such as optimal sensor network density and topology.

“…This complication results in need to expand beyond analytical models and algorithms, and to include complex simulations. An extensive and comprehensive recent overview of methods is given in Oluwaseye et al [13]. The authors describe the approaches used and problems encountered by hundreds of authors, over a span of 50 years.…”

“…Because of their liquid environment, the great majority of authors also must contend with modeling system hydraulics, and as mentioned above, this hugely complicates analysis and makes difficult the solution to even moderate-sized problems. An important paper not cited by Oluwaseye et al [13] is one by Giudicianni et al [14]. In this paper, the authors simplify the problem by not requiring any hydraulic modeling of the water distribution system, focusing only on the topology of the distribution network, mathematically a graph.…”

Placing sensors in sewer networks: A system to pinpoint new cases of coronavirus

We consider a proposed system that would place sensors in a number of wastewater manholes in a community in order to detect genetic remnants of SARS-Cov-2 found in the excreted stool of infected persons. These sensors would continually monitor the manhole’s wastewater, and whenever virus remnants are detected, transmit an alert signal. In a recent paper, we described two new algorithms, each sequentially opening and testing successive manholes for genetic remnants, each algorithm homing in on a neighborhood where the infected person or persons are located. This paper extends that work in six important ways: (1) we introduce the concept of in-manhole sensors, as these sensors will reduce the number of manholes requiring on-site testing; (2) we present a realistic tree network depicting the topology of the sewer pipeline network; (3) for simulations, we present a method to create random tree networks exhibiting key attributes of a given community; (4) using the simulations, we empirically demonstrate that the mean and median number of manholes to be opened in a search follows a well-known logarithmic function; (5) we develop procedures for determining the number of sensors to deploy; (6) we formulate the sensor location problem as an integer nonlinear optimization and develop heuristics to solve it. Our sensor-manhole system, to be implemented, would require at least three additional steps in R&D: (a) an accurate, inexpensive and fast SARS-Cov-2 genetic-remnants test that can be done at the manhole; (b) design, test and manufacture of the sensors; (c) in-the-field testing and fine tuning of an implemented system.

“…Potable water is vital for human existence and it is a significant resource for several industries such as food and beverage, petrochemical, agricultural, oil and gas among others. Studies have shown that the consumption of contaminated water has severe consequences on plants, animals and human and may constitute serious health challenges and socio-economic nuisance [1][2][3][4]. Despite this information, there are lingering potable water crises across the world, for example, the most communities in developing countries are still struggling to meet the consistent demand of potable water supply for domestic and industrial use.…”

The diversity of water pollution and the depletion of some water resources have continued to linger despite several governmental and non-governmental programmes, especially in developing countries for water quality sustainability. This problem has reduced potable water availability, and it has increased water-related diseases in these countries. These problems are severe, mostly, in drought prone areas where water supplies and treatments are still at an infant stage. Hence, researchers are proposing the application of nanomaterials for water treatment and desalination. However, nanomaterials can also turn to be water pollutants that can threaten the public health if handled carelessly. This study, therefore, presents the applications and implications of nanomaterials in relation to water treatment and water quality. The review results highlighted the state-of-the-art and prospects of nanomaterials for water desalination and water quality production.
