Wastewater Treatment

Wastewater Treatment Plants Come in All Shapes and Sizes

Lynn, Massachusetts Regional Wastewater Treatment Plant

118.8 million dollar plant construction

Treats wastewater from four cities/towns (over 134,000 residents)

Can treat over 100 million gallons per day

…run by 33 employees!

Why Do We Need to Treat Wastewater?

• Alternatives:• Store massive amounts of wastewater in tanks/basins• Mix wastewater into clean lakes and rivers

• Consequences of poor wastewater treatment:• Leaks/spills!• Poor air and water quality• Health problems

Why Is The Design of Wastewater Treatment Facilities Important?

• Capacity to handle waste stream• Energy use • Danger from the treatment process itself

Biggest Wastewater Disasters!• London, 1878 – infrastructure unable to keep up with

population growth; cesspools overflowed into Thames River; members of parliament soaked curtains with chemicals to keep out smell

• Hawaii, 2007 – 48 million gallons of sewage overflowed into Ala Wai Canal; closed down all nearby beaches

• Mexico, 2011 – 200 homes flooded by sewage after pipe burst; 3 children injured

Just this month!

RPI EcoEd + TamaracEnvironmental Engineering Research Program

Together, the research group will produce • a timeline documenting the development of Tamarac’ wastewater facility

• a photo essay describing components and the process of Tamarac’s wastewater system

• a photo essay describing how wastewater treatment has developed over time, alternative plant designs, laws governing wastewater treatment and issues arising through their operation

• a short lesson for third grade students, contributing to their understanding of “systems.”

• Time permitting, we may also produce a film about our research.

• There also could be opportunities for fieldtrips.

RPI EcoEd + TamaracEnvironmental Engineering Research Program

The research will be presented

• to the Brittonkill Board of Education

• to interested classes

• for critical review and public viewing at RPI’s Earth Week Festival
