WASTEWATER MEASUREMENT RESOURCES

• Utilizing Optimization, Thames Water Unearths Significant Leakage Benefits While Maintaining Service Levels

  Thames Water worked with eight₂0 and Optimatics to investigate whether changing dynamic valve settings and installing additional booster pumps to service tall buildings could help reduce leakage losses within their networks.

• Water Service Provider In Melbourne Finds Success In Transparent Asset Management Optimization For Mains Renewal Program

  City West Water teamed with WSP and Optimatics to determine a least cost and least-risk renewal program for ageing distribution mains supplying inner Melbourne, Australia. The optimization of the inner Melbourne distribution mains was carried out to determine an optimized pipe renewal strategy that minimizes pipe renewal costs and future risk (including probability and consequence of asset failures) while ensuring service performance standards are maintained.

• SWAN Corner: Wet Weather Measurement Means More Than Scratching The Surface

  Wet weather is a continuous concern for wastewater utilities. Rain-derived infiltration and inflow (RDII) challenges the collection system capacity. It can potentially result in overflows in the collection system and even the wastewater recovery facility (WRF) in extreme cases. These overflows can threaten public health and the environment. Additionally, higher flow volumes associated with wet weather will increase operating costs at the WRF.

• New Challenge: Put Technology To Work To Protect Drinking Water

  You likely remember when, this past summer, half a million people who live in the Toledo, Ohio, area were told not to drink the water coming out of their taps for several days. A state of emergency was declared because of a harmful algal bloom, which released toxins into the water that could have made many people ill.

• Smart Metering Not An All Or Nothing Proposition

  Water utilities of all sizes face daunting challenges.  Small utilities face the same challenges as large utilities, but have to do more with less.

• Special Gas Chlorination System Replaces Tablet System At WWTP, Providing Enhanced Safety Needed For Gas Option, While Cutting Chemical Costs

  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.

• What Is A World-Class Utility, And How Does Yours Become One?

  Water utilities are tasked with ensuring a sustainable and safe supply in addition to achieving business and service excellence goals. These goals are typically based on criteria that measure operational performance, meeting bond covenants, and customer satisfaction.

• The Trick To Managing Vertical Assets

  We get asked all the time; “Do you do vertical assets?”  I always respond with: “Of course we do, but what do you want to do with vertical assets?”  And that is where the discovery begins…

• Grad Student Reimagines Oklahoma City With Green Infrastructure Design Using InfoDrainage

  Andrea Tavera, a former University of Oklahoma graduate student, used Innovyze drainage design software to promote LID-based, green infrastructure design in hopes of resolving Oklahoma’s two greatest drainage challenges caused by stormwater runoff: excessive flooding and pollution. 

• Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy

  Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.
