Water Quality Event Detection for Urban Water Security and Urban Water Management Based on Hydro-toxicological Investigations. (W3-Hydro)
Battle of the Water Networks II
The Battle of the Water Networks (BWN-II) is the fourth in a series of Battle Competitions dating back to the Battle of the Water Networks in 1985 and more recently the Battle of the Water Sensor Networks in 2006 and the Battle of the Water Calibration Networks in 2010. (WDSA2012)
optiEDS – Event Detection System
Water quality monitoring is one component of a Contaminant Warning System (CWS) and consists of a network of monitoring locations throughout the water distribution system. Each station contains a suite of sensors that measure standard water quality (WQ) parameters such as chlorine, total organic carbon (TOC) and pH. A growing body of data demonstrates that deviations in one or more WQ parameters from an established base-state can provide early warning of contamination. However, the normal variability in distribution system water quality, coupled with the large amount of data, makes it a challenge to successfully detect transient contamination incidents (USEPA EDS challenge). optiEDS
Battle of the Water Calibration Networks
The Battle of the Water Calibration Networks (BWCN) is the third in a series of “Battle Competitions” dating back to the Battle of the Water Networks (BWN) in 1985 and more recently the Battle of the Water Sensor Networks (BWSN). The BWCN calls for teams/individuals from academia, consulting firms, and utilities to propose a calibration methodology and apply it to a real water distribution system. The results of the BWCN where presented at a special session of the 12th Water Distribution Systems Analysis Symposium in, Tucson, Arizona in September 2010 (http://wdsa2010.org/). BWCN
Battle of the Water Sensor Networks
The Battle of the Water Sensor Networks (BWSN) will objectively compare the performance of contributed sensor network designs, consisting of a set of sensor locations. Independent research teams and practicing engineers will contribute their designs for two different water distribution networks. Each team will be asked to develop designs according to a precise set of rules to facilitate design comparisons. These rules specify the design performance metrics, the characteristics of contamination events, and the detection technology used to raise an alarm.

Water Security Using Online Contamination Monitoring
Pipe networks may be highly vulnerable to a deliberate terrorist contamination injection that can spread throughout the system. This project aims to a) develop and apply a methodology for optimally locating sensors b)develop and apply a methodology for identifying the sources of pollution c)develop and apply a methodology for pollutant containment d) develop and apply analytical tools for on-line monitoring to detect and destroy particulates in drinking water, and e) develop and apply a new technology for bacterial identification and typing in drinking water.

The aim of the POWADIMA research project is to establish the feasibility of introducing optimal, real-time control of water distribution networks. Since demand is fluctuating continually, it is necessary to adjust the control apparatus frequently if optimal or near-optimal control is to be achieved. The objective function is to meet the forecast demands at minimal operating cost, subject to operational constraints such as statutory minimum pressure, minimum acceptable flow to avoid stagnation etc. This implies minimizing pumping costs which are the largest component of the operating cost (hence the acronym POWADIMA).
