Eastern Municipal Water District (EMWD) serves about 142,000 customers in Riverside County, CA. The EMWD service area is one of the largest for any water district in arid southern California. On the drinking water side, EMWD manages two water treatment plants and over 15 reservoirs. With 70% of the district’s water coming from the Metropolitan Water District with chloramine disinfection, EMWD has become reliant on chloramine disinfection to manage long transmission lines and longer detention times.

Utility workers will remember a time when meter reading meant driving to a customer’s house, walking up to their meter and manually recording water use. Those days were replaced with the now standard use of walk- and drive-by meter readers. That standard, like its predecessor, is poised to be supplanted by the next wave in metering technology.
The district manager for the Pinetop-Lakeside Sanitary District (AZ) reports that a special gas chlorination system, featuring unique components and controls, and manufacturer-supplied service, has effectively replaced a chlorine tablet system.
To get the latest on the Promag 400 line of electromagnetic flow meters featuring specialized sensor technology, Water Online spoke with Endress+Hauser’s Flow Product Marketing Manager Nathan Hedrick and Environmental Industry Manager Alan Vance. The two served up details on the sensors’ web capabilities, proprietary Heartbeat Technology, and advanced safety features.
The public works director responsible for a southwestern U.S. city’s drinking water supply reports multiple benefits from replacement of a problematic peristaltic pump system with a special liquid vacuum feeder system for bleach, liquid ammonium sulfate (LAS), and polyphosphate feeds at one of its well sites.
When it comes to disinfection at treatment plants, chlorine has quite the reputation. To some, it’s known as a reliable and trusted solution. To many others, especially among the public at large, it’s looked at with skepticism and concern – but that may be simply a matter of not knowing the facts. Either way, it’s one of the ubiquitous aspects of water and wastewater disinfection… and for good reason.
This is a story about three cities in North Carolina: Albemarle, Concord and Kannapolis. Albemarle, 40 miles east of Charlotte, had excess capacity in its water system and needed new customers to defray costs.

Loudoun Water, a water utility serving customers in Loudoun County, Virginia, recently undertook an innovative, green approach to supplying water in the face of game-changing growth and development.
In October, the WateReuse Association’s 2016 Potable Reuse Summit will bring water professionals of all levels together to hear success stories and find out how to implement potable reuse programs in their own communities.
This year's Annual Conference and Exposition (ACE16), held by the American Water Works Association (AWWA) from June 19 to 22, was the first following the tragedy of Flint — a time when the drinking water industry is under intense scrutiny.
The Water Research Foundation has released the results of a study testing the most effective method for treating PFOA and PFOS in drinking water.
Here in the post-Flint era of municipal water operations, and for the foreseeable future, the loudest mandate for utilities will be to "get the lead out" of our distribution systems. Until such time that all lead lines are replaced, control strategies will need to be employed.
In the midst of this U.S. presidential race, a thought about Ronald Reagan (apolitical, I promise): Known as the “Great Communicator,” it’s certainly no coincidence that Reagan was an actor before becoming president; and honed communication skills, especially in times of trouble, are vital to effective leadership.
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
An industry expert addresses technology and compliance concerns regarding the U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2).
This article is for those of you who need to install a new or redo an existing pH loop. These tips can help ensure accurate and consistent readings.
An increasing number of technology industries are turning to cooling towers to remove excess heat from buildings or processes. Server farms or server clusters are typically located between the system switches and the routers, and the removal of heat from these facilities is critical to their optimal function.

High levels of radionuclides (uranium/radium/etc.) in drinking water aren’t very common, but they are very dangerous. If you’ve long dealt with radionuclides, you’re familiar with the treatment requirements — but are you treating as cost effectively as possible?
The world has watched this summer as countless customers in Detroit have had their water shut off due to nonpayment.
The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site. The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product puriﬁcation needs, ﬁnd alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and proﬁtably.
For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.
The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
The groundwater that a southern Louisiana water utility supplies to local residents has traditionally carried a high amount of organic material and color. In the past, the organics were oxidized and broken down by chlorination, but this practice had gone out of favor due to production of disinfection by-products (DBPs) such as Trihalomethanes (THMs) and Haloacidic Acids (HAAs).
