Extreme Water Filtering – Consider High-Flow Systems To Save Costs And Reduce WasteIn an era when everything is done to the extreme – from sports, to home makeovers, to weather predictions – it should come as no surprise that the world of water filtering has joined the crowd. “Extreme” filtering, so to speak, is achieved through the use of high-flow cartridge systems – smaller designs that are able to handle much higher water volumes and pressures at lower costs and with less maintenance. By Robert LeConche, President, Shelco Filters

AMR System Delivers Outstanding Efficiency While Improving Water Conservation In Pacific NorthwestPublic Utility District No. 1 of Skagit County (Skagit PUD) in Washington state was at a crossroads, facing a number of challenges related to its meter reading system. Because the utility was using a touch-read/visual-read system, it was highly dependent on its water meter readers’ acquired route knowledge. Two of the PUD’s three meter readers were planning to retire soon, and it would take at least a year to hire and train new employees to fill their experienced shoes. At the same time, the community was growing at a steady pace, and a significant number of its existing meters were reaching the end of their useful lifecycle.

Monitoring ORP To Help Determine Arsenic In Private WellsArsenic is one of the most common elements in the earth’s crust and is commonly found in many locations at varying concentrations. The Midwestern United States has locations that are heavily laden with arsenic because of certain geological settings and conditions. This naturally-occurring arsenic can leach into groundwater potentially causing elevated levels of arsenic in drinking water supplies. The primary pathway that exposes arsenic to humans is through drinking water.
