    Value-Based Procurement: Steps In The Right Direction

    As a means of encouraging the growth of new technologies and improving operating costs, water and wastewater equipment manufacturers have long advocated for changing the mindset of equipment procurement from low-bid to lowest life-cycle cost evaluation.This have proven to be a very daunting task. 

  • Emergencies: Preventing, Preparing, And Responding
    Emergencies: Preventing, Preparing, And Responding

    Population health is a primary concern of water utilities, whether water demands are typical (daily demands) or an out-of-the ordinary event occurs and threatens the continuous, safe supply of potable water. Water utilities must be prepared to respond to emergencies before they occur, and this is where hydraulic modeling can be particularly useful.

  • Water Vs. Climate Change
    Water Vs. Climate Change

    Recently, the United Nations held a conference in Morocco related to climate change issues. The location of the conference had significant meaning because Africa has become a bellwether for the rest of the world when it comes to climate change. Desertification and rising sea levels both impact countries all over that continent.

  • Ignition Increases Flexibility, Lowers Costs For Two Water Utilities
    Ignition Increases Flexibility, Lowers Costs For Two Water Utilities

    When Park City Water in Utah needed a new system for supervisory control and data acquisition (SCADA) and human-machine interface (HMI), it picked the same solution chosen by its neighbor, Mountain Regional Water (MRW) District. Both MRW and Park City have seen significant improvements since switching from their previous SCADA systems to Ignition. MRW saves more than $400,000 per year on energy with greater control from Ignition. Park City saves the equivalent of one full-time employee by using Ignition to automate its reports to a state agency. 

  • The Vanguard of Patient Centricity: Patient-Led Clinical Trials
    The Vanguard of Patient Centricity: Patient-Led Clinical Trials

    Amid the AIDS epidemic during the late 80’s, Dr Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, found himself at a crossroads. As a long-time proponent of the traditional “research to approval” drug development model, involving randomized clinical trials and lengthy regulatory reviews, Fauci was faced with the realization that this traditional approach would be of little benefit to AIDS patients without the luxury of time. Something had to be done. But what?

  • Water And Food: One Man’s Vision
    Water And Food: One Man’s Vision

    Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.

    City Of Dallas Captures An Additional 600,000 Gallons Of Billable Water In Four Months

    After analyzing annual water loss audits for the city of Dallas, GA, the team discovered significant issues around non-revenue water. In 2014, real and apparent water loss accounted for 31.3 million gallons — nearly 20 percent of the city’s total water supplied for the year — which meant lost revenue for the city.

  • WWTP Air Handling Control Philosophies: Do’s And Don’ts
    WWTP Air Handling Control Philosophies: Do’s And Don’ts

    Without an appropriate control strategy, even the best wastewater treatment plant (WWTP) equipment can struggle to deliver maximum efficiency. Because energy costs represent up to 60 percent of WWTP plant operating expense, air distribution designs and changing loading (biochemical/biological oxygen demand [BOD]/chemical oxygen demand [COD], ammonia) demands require control strategies designed to adapt to all eventualities efficiently. The following checklists, plus important Do’s and Don’ts, can help in identifying an underperforming control strategy and developing a better one.

    California Approves Funds For Water Projects, Large And Small

    The past few months have been highly eventful for California water watchers.  In June, by a margin of 57 to 43 percent, California voters approved Proposition 68, a $4.1 billion parks and water bond that will provide approximately $1.3 billion for water-related projects across the state.  Then in July, the California Water Commission approved $2.6 billion of funds authorized by Proposition 1, passed by the voters in 2014, to be used for eight new water storage projects.  These developments reflect that California is taking a bold and multi-pronged approach to addressing its water needs, investing both in new large infrastructure projects and in more modest projects to improve the state’s existing resources and assets.

EPA’s Non-Targeted Analysis Collaborative Trial (ENTACT) was formed in late 2015 and includes nearly 30 academic, government, and industry groups. Non-targeted analysis involves analyzing water, soil and other types of samples to identify unknown chemicals that may be present, without having a preconceived idea of what chemicals may be in the samples.
