Globally, 780 million people lack access to clean drinking water that meets minimum Western standards for health and safety. As a result, 3.4 million people die each year from water based bacterial infections. In the US, as in most developed countries, we take our water supply and sewage treatment services for granted, which is a testament to our municipal operators. But the future will be much more challenging, as cities are forced to deal with aging infrastructure that’s decaying after generations of no investment. In 2010, the EPA estimated the capital cost to modernize US water infrastructure at $91 billion, stating that further delays will exponentially increase these costs and endanger public health. A 2012 report by the American Society of Civil Engineers concluded that, “The growing gap between capital needs to maintain water and wastewater infrastructure, and the investments to meet those needs will result in unreliable drinking water and inadequate wastewater treatment.” Like it or not, we can count on higher rates and intermittent service ahead as we’re forced by mother time to reinvest into our nations water infrastructure. At this water treatment facility, an EchoSonic ultrasonic level transmitter is installed over each clarifier. The 4-20 mA signal is connected to their SCADA system.
