The pipelines that municipalities use to deliver drinking water to their residents take a beating. Large cities pump tens of millions of gallons of water to their customers every day. And many of the pipes that municipalities rely on to transport drinking water and treat wastewater are coated with decadesworth of grime and pollutants.
It’s little surprise then, that a growing number of municipalities face a problem: Their aging pipes are so filled with sludge and biofilm that it is reducing the speed at which they can pump water. This means that pumps have to work harder in these systems, increasing the energy costs and the expenses that these cities face when providing drinking water to residents and commercial buildings.

From time to time Acumen offers free courses to assist persons in gaining valuable skills for leadership in the 21st century. By partnering with colleagues, friends, family members and even like-minded individuals around the world one can tackle courses that ensure accountability, as well as, create a better learning experience for those participating in the courses.
I have been recently provided with a list of their free fall courses (Running from September 2017 – February 2018). To learn more about Acumen courses and read articles from their Acumen Journal click here.
I do hope you take the opportunity to try out some of their courses. Enjoy!
The 32nd Annual WateReuse Symposium will be held on September 10-13 2017 in Phoenix, AZ. The Annual WateReuse Symposium is the nation’s preeminent conference on water reuse and the only conference that is dedicated solely to advancing the policy, technology, innovation and public acceptance of water reuse.
This year’s Symposium will feature:
- More than 100 presentations, panel discussions, and workshops.
- A technical tour with a stops at the Town of Gilbert Riparian Preserve at Water Ranch and the Scottsdale Water’s Reclamation and Advanced Water Treatment Plant.
- The AZ Pure Water Brew Challenge —sample beers made with purified recycled water.
- Dinner with dancing at The Duce and an optional baseball game (Arizona Diamondbacks versus the Colorado Rockies).
- Annual awards luncheon.

The International Conference on Estuaries and Coasts is expecting the submission of research papers. All authors of selected papers will be invited to the event.
The International Research and Training Center on Erosion and Sedimentation (IRTCES), one of regional allies of GWP China, advocates its upcoming event “the 6th International Conference on Estuaries and Coasts”, on August 20-23, 2018 in Cean, France, together with the University of Caen Normandie and the Group of Scientific Interests.
Under such theme “Estuaries and Coasts in times of Global Change”, it includes several topics as below:
- Saline intrusion and sea level rise: measurements, modelling and forecasting their impacts to economic development and human lives ;
- Waves and Tsunami: Measurements, modelling, forecasting and warning system ;
- Estuarine and coastal flows and their evolution by climate change ;
- Sediment transport and morphological change in estuaries and coastal zones ;
- Megacities development and coastal floods under the threat of sea level rise and climate change : Observation, modelling, forecasting and early warning systems ;
- Environment and ecosystem change in estuaries and coastal zones in time of global change ;
- Integrated Coastal Zone Management for sustainable developments in global change context ;
- Environment and Marine Renewable Energies.
HIGHLIGHTS for whom have interestes in the theme and its topics—
- Oct 1, 2017 : submission of abstracts
- Dec 1, 2017 : notification of abstract acceptance
- Jan 31, 2018 : submission of full papers
- Mar 31, 2018 : notification of paper acceptance
- Apr 30, 2018 : submission of camera-ready Manuscripts
Papers should provide detailed information on the objectives of the study, the methodology, the main results and major conclusions. They should mention the name, affiliation of authors, and Email of the corresponding author.

We all know the significance of gathering data for the effective running of our organization. Such data is ensured by acquiring reliable rain and stream flow gauges. In her article below Sarah Witman discusses guidelines put forward by the World Meteorological Organization, as well as, a recent study by Keum and Coulibaly, which has expanded on such guidelines to assist persons on determining optimal locations for such gauges and how to better understand information from stream gauges.

Data from continuous water quality monitoring networks inform critical activities across every sector of the surface water industry today, from meeting federal and state water quality standards and ensuring safe recreational waters, to researching and managing the effects of climate change. As such, continuous water quality monitoring networks must produce results that meet the data quality objectives for a given program while operating within the constraints of limited human resources and budgets.
Until now, however, deploying and cost-effectively maintaining an autonomous monitoring network has been limited by lack of advancements in sensor technology.
Join David A. Bossie for a free online training webinar exploring how innovations in water quality sensor design are challenging old beliefs about the ability of autonomous, long-term monitoring networks to produce representative, comparable data at a price point within reach of most organizations.
Specifically, we’ll learn how you can operate pH sensors hands-free for months that previously required calibration every 1-2 weeks. We’ll see how turbidity sensor accuracy is no longer worrisome due to improved linearity across the range of 0-4000 NTU, and how the use of LEDs and filters provide stability not found with incandescent light sources. Finally, we’ll explore how you can deploy conductivity sensors in biofouling environments without loss of accuracy thanks to an innovative, open-faced design that allows wiping.
Attendees can expect the discussion and education of the following learning objectives:
- Learn how limitations of existing technologies in continuous water quality-monitoring networks affect data quality and network maintenance costs.
- Explore how the evolution of the pH sensor design results in improved stability, data quality and reduced calibration frequency.
- Discover how improved turbidity sensor design increases linearity and accuracy in clear and high sediment environments.
- Examine how improved conductivity sensor design coupled with anti-fouling systems improves performance in high biofouling environments.
