Regular testing of water samples for E. coli and Total Coliform is a crucial part of water safety. Current standard laboratory microbiological water tests are commonly not accessible in rural communities, require a high skill level to undertake, and do not offer timely results to waterworks operators. In the current scheme, operators typically have to collect samples from water treatment sites and points within the distribution system. The samples have to be shipped within a prescribed time frame to large centralized laboratories for testing and the results are returned 2-5 days later.
To address these issues, Roshan Water Solutions has developed VeloCens™; a portable reader and nanotechnology-based disposable cartridge system used for rapid, on-site microbiological detection and enumeration in water. It allows operators to automatically log and analyze samples, and report results within 1 hour; representing at least a 12-fold time decrease compared to standard lab tests. Product plans include enabling communication with a secure central database providing operators as well as, community and government officials access to data 24/7/365.
With a rapid detection system, officials can take required measures faster and avoid outbreaks; the most serious being the E. coli outbreak of 2000 in Walkerton, Ontario which saw 2500 people ill and 7 lives lost. In Alberta, as of July 8, 2019, there are 16 reported active boil water advisories affecting 200,000 Albertans, one dating back to 2011 (Kehewin Cree Nation). Having the ability to spot check water quality at any point in the water treatment and distribution network, provides communities with a tool to troubleshoot and quickly identify when water is SAFE for public consumption.
With VeloCens™, microbiological testing in drinking water can be done "anywhere by anyone". In this presentation, the working principles of VeloCensTM along with the evolution of a science-based proof of concept to a working technology will be explained. In addition, the current state of the technology and the future development path to a market ready commercially available product will be described.
