Let It Rain


 As wastewater utilities look for cost-effective methods to treat wet weather flows, they might want to consider coarse monomedia filtration. Unlike conventional filtration systems, this process has proven to be a cost-effective option for treating combined sewer overflow (CSO) and sanitary sewer overflow (SSO) streams at remote locations.


Just Right


Once upon a time, the University of California—Davis wastewater treatment plant had a manually controlled aeration system for its oxidation ditch. Frustrated with limitations on the system, treatment plant staff began looking for an option that would handle constant variation while providing just enough oxygen to meet treatment needs. 



Waterborne Anthrax Resistant to Chlorine


A recent study has revealed that the spore-forming bacterium Bacillus anthracis, or anthrax, may be resistant to the traditional form of chlorine disinfection used in water treatment.

  • Gather ye solids. Under a consent order to minimize untreated wastewater discharges during wet weather events, Columbus, Ohio, pilot-tested two promising high-rate clarification systems. Both use ballasted flocculation to treat wet weather flows.
  • Rain check. Today, many cities are challenged to control CSOs and SSOs and build abatement facilities to improve water quality. Storage tunnels can help keep overflows at bay.
  • Cutting through the FOG. Fats, oils, and grease are the bane of collection systems. But when treated properly, FOG can yield both environmental and economic benefit.
  • Fix it or replace it? Wonder whether you should repair that recirculation pump or buy a new one? Planned condition assessments saved this California municipality more than $100,000.
  • Perfect project planning. Bypassing 50 mgd while repairing a 12-ft by 9-ft concrete conduit is no simple task. But meticulously planning and constant communication enabled one utility to manage such a project while maintaining its 11-year record of no numerical discharge permit violations.
  • Confidence boost. Get more out of your mandatory drinking water reports. Why spend the time and money to produce a bare-bones flyer, when a little more effort investment can turn your Consumer Confidence Report into your most effective public relations tool.
  • Communication Is king. Faced with major construction in a crowded neighborhood, planners reached out to the community. What they found was valuable input to the project’s design and construction phases and reduced costs.
