COLLECTION SYSTEMS RESOURCES

• New Nashville Equalization Facility Helps Manage Wastewater Flows

  Workers in Nashville recently completed an $18.9 million project to supplement an existing pump station to help manage excessive flows in the existing sewer system. The new equalization storage tank is the centerpiece to the facility, and those tanks play an important role in wastewater management.

• Optimization Strategies To Streamline Community Wastewater Utility Operations

  The availability of robust, stable treatment systems with simple treatment processes and O&M is key to serving growing community wastewater treatment demand.

• Calcium Nitrate Replacement Via SulFeLox®

  Faced with increasing costs for controlling hydrogen sulfide in its wastewater collection system, the City of Bakersfield, California commissioned an evaluation of its program in 2019.

• All-Terrain Sewers Got A Good Beat, And Indy Dances To It

  When Susan Raccoli penned "Beneath the Ground, Raw Sewage" (to the tune of "St. Christopher") in 1993, her hometown of Indianapolis inspired the lyrics. "Our septic failure is a curse," she wrote, with verses alluding to its "Third World"; smells, high water tables, clay soil "which does not perk," typhoid, cholera, mosquitoes singing "with glee," and the "expensive" but desired transition to gravity sewers.
• The Future Of Decentralized Onsite Wastewater Treatment Systems

  Numerous factors coalesce to create a rising demand for decentralized solutions.
• WWEMA Window: Designing Wastewater Treatment Equipment For Resiliency

  It is a known issue that wastewater infrastructure is aging and is in need of significant investment to upgrade or replace systems to operate safely. Age is not the only factor driving system replacements. Wastewater itself has changed, which means what flows through collection systems and into treatment plants is different than what it was 50 years ago. At home, lower-flow toilets translate to less water to move flushed solids.

• Cost x Carbon x Energy: Passive Onsite vs. Centralized Wastewater Treatment Systems

  A new study quantifies the difference between onsite wastewater treatment and centralized systems in terms of actual costs and those to the environment.
• Kearney, MO, Wipes Up Treatment Trouble With Brushless Screening

  When the Kearney, MO wastewater treatment plant began plans to upgrade its headworks they choose JWC Environmental’s Brushless Finescreen Monster to replace its old coarse screen.

• Maximizing Solids-Handling Performance Of Municipal, Commercial, And Industrial Pumps

  The rise in the use of disposable wipes and other non-dispersible debris is driving the need for more efficient handling of solids in pumps at municipal lift stations and wastewater treatment plant headworks.

• Wastewater Is Anything But A Waste: It Could Even Prevent The Next Pandemic

  Ari Goldfarb, CEO, Kando, discusses how innovative technologies and artificial intelligence tools are advancing wastewater analysis and could potentially mitigate the effects, or even prevent, future pandemics.
