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.

Secure Network Information Readily Available To Enterprise UsersPortland Water Bureau, more than 100 years old, is a public water utility located in Portland, Oregon. It is responsible for the supply, treatment, and delivery of water to about 935,000 consumers in parts of Multnomah, Washington, and Clackamas counties in Oregon — nearly one-fourth of the population of the state. This service involves approximately 35 billion gallons of water annually. In 2011-12, more than 566,000 of those consumers were retail customers served directly by the utility. Another 368,000 consumers are served by the utility’s wholesale customers, including suburbs of Portland, water districts, and private water companies.

Stainless Steel E-Series® Ultrasonic Meter
E-Series Ultrasonic water meters from Badger Meter use solid-state technology in a compact, totally encapsulated, weatherproof, and UV-resistant housing, suitable for residential and commercial applications.
Remote Pressure Monitoring System
Several years ago, Mueller began a journey to develop a user friendly and co st-effective technology to continuously and remotely monitor pressure at any point within a potable water distribution system. The technology involves threading a sensor onto a corporation valve to transmit pressure readings. The pressure sensor, typically installed one per District Metering Area (DMA), reports at userdefined intervals via cellular service and a Mueller-hosted secure web server. Beginning with pressure monitoring, Mueller has created a communications backbone that utilities can integrate into its monitoring systems or use as a stand-alone monitoring platform.

Increase Revenue With New Commercial Metering TechnologyRevenue for water utilities is circling the drain. Most commercial water meters can stand up to the high water flow of commercial water customers, but these same meters often have a hard time measuring low water flows and retaining accurate meter reads over time and continuous flow conditions. Grocery stores, for example, do not pay for the scant amount of water used for produce misters because it passes through many commercial water meters without detection. These low flows add up to big dollars and are forcing water utilities to take a hard look at the accuracy of their meter fleet.

Hydrogen Sulfide Removal From Water Using AquaSorb® CX-MCAThe “rotten egg” odor in some water supplies is caused by sulfide in water. Sulfide can be treated using oxidation techniques, the goal being to convert the sulfide to high oxidation state species such as sulfate to eliminate the taste and odor concerns. Traditional oxidation techniques such as ozone and chlorine can be used, but can be expensive due to the equipment required to add and monitor the oxidant, and can lead to by-products such as trihalomethanes (THMs), which are regulated in drinking water supplies.
