Purpose and Background

Sponsored by the Water Supply, Treatment and Distribution Engineering Committee and the EWRI Institute

This presentation will provide the basics of riverbank filtration for water supply in the United States and recent advances /developments. Riverbank filtration is considered a low-cost treatment technology and has the potential to avoid filtration fully or reduce the use of chemicals in water treatment. RBF has been used by several utilities located along riverbanks (and along lakes) to produce drinking water.

When wells are placed in alluvial aquifers adjacent to rivers, in portion of the river water is induced to flow pumping. A combination of physical chemical and microbial processes helps in improving the water quality as the water moves from the river to wells. For the riverbank filtration systems to work effectively, there must be reliable and generally good quality source water and there has to be hydraulic connection between the river and the well in the aquifer. RBF systems are functional in the US since the late 1930s and early 1940s. In Europe, they are functioning to provide public water for more than a century. Depending on the location and source water quality, some utilities do not have additional filtration. They simply disinfect and supply the water. In this webinar we will discuss planning design and construction processes for RBF systems, assess their performance in terms of water quality improvement and address their effectiveness in removing some of the contaminants of recent concerns.

Learning Outcomes and Session Benefits

Upon completion of this course, you will be able to:

• Explain how RBF as an alternative to traditional water treatment
• List what cities in the US are operating RBF systems and how long
• Describe how specific problem a utility face was resolved by switching to RBF from traditional river intakes
• Identify what chemicals can be removed by RBF systems
• Explain the process for the removal of pathogens and indicator bacteria through RBF
• Describe an international perspective on riverbank filtration

Assessment of Learning Outcomes

Learning outcomes are assessed and achieved through participation in the live Q/A with our speakers, and by responding to the post- session survey. If the course is taken On-Demand, there will also be a 10 multiple choice question post-test.

Who Should Attend?
