Every four years, the American Society of Civil Engineers (ASCE) releases a new report card on the state of our nation’s infrastructure, and their 2013 grade for both water and wastewater was a “D”. That report estimated that the infrastructure needed $3.6 trillion in investment by 2020. I do not look for a significant movement in our current grade for either water or wastewater with the 2017 report when it is released this year, because the funding at the level required to significantly change our infrastructure has not been made except at a few local utilities.
Steinbach is the third largest city in Manitoba and one of the fastest growing census agglomeration areas in Canada with a population of about 50,000 people. Though Steinbach is primarily an agricultural community, it is also the regional economic hub of southeastern Manitoba. Due to the age of the wastewater control system, the city decided it was time for some new technology. This profile will describe the process of that upgrade and why they chose VTScada.
Using ruggedized fiber optic cable, connectors, and enclosures can ensure that network communications run reliably at high speed — far into the future.

The Hudson River, in the Capital District of Albany, NY, is a popular recreational area for boating, swimming and fishing. Unfortunately combined sewer overflows following storm events and snow melt from sewer systems dating back to the 1800’s were causing increased fecal coliform counts which in turn resulted in health alerts and limited access to the river. After considering several alternatives, the Albany County Sewer District selected a Wedeco Duron 60i2-2.5X4, with high power Ecoray 600W lamps, for their disinfection system.
Research into manmade, floating wastewater treatment wetlands may mark the first step into a new world of sustainable nitrogen removal.
Now that you have returned to the role of private citizen — though, admittedly you are a private citizen with millions of eyes focused on you — I want to encourage you to continue your great work promoting the health of our nation’s children. Your emphasis on exercise and nutrition, jobs and support for veterans, and education have touched millions of Americans of all ages and all backgrounds. Now it’s time to bring in the most common denominator and the first step toward good health — access to clean water.
On a warm December day, I stood in a jojoba field in the Negev Desert in southern Israel and watched water slowly seep up from the ground around the trees. First a tiny spot, then spreading, watering the plants from deep below. This highly efficient system is known as drip irrigation, and I was there to meet with the world’s leading drip irrigation company, Israel-based Netafim.
Farmers in Uganda and in developing countries around the world are facing major energy and waste management issues. There are anaerobic digestions systems to help farmers manage agricultural waste from plants and animals, but there’s a problem.

As climate change continues to advance, some are wondering whether our wastewater systems are equipped to handle the future.
A power plant in North Carolina’s wastewater is contaminated by coal ash generated from power plant operations and removed in the scrubber system. The wastewater is sent to a settling pond after polymer injection to allow for sedimentation. The wastewater then travels to a second, third and fourth pond for additional settling. Plant land restrictions required the elimination of the last settling pond. This initiated the search for a treatment/polishing system to maintain a TSS of less than 25 PPM to meet discharge requirements.

Aerobic granular sludge has been extensively researched over the last two decades as a part of the search for more sustainable wastewater treatment solutions. Conventional activated sludge (CAS) systems have key disadvantages such as slow settling flocculent biomass necessitating large clarifiers and low reactor biomass concentrations (typically 3-5 kgMLSS/m3), large treatment system footprints and relatively high system energy usage. It has been shown at the lab, pilot and the full scale that aerobic granular sludge has distinct advantages, when compared to CAS systems, including improved settling characteristics, which in turn allows for higher biomass concentrations and hence more compact treatment systems.
