In this presentation, we will discuss what happens to low-income countries like Zanzibar, when tourists arrive and continue their western lifestyle in a tropical setting with scare resources. We will among other focus on the wastewater generated, the consequences of water use and the tons of solid waste generated by the tourists.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Our urban sewer systems house - and feed - thriving communities of microorganisms. However, we currently know little about how these communities function. For example, do they differ across geography or respond to changing seasons? To begin to answer these questions, researchers characterized the bacterial communities from two wastewater treatment plants and several residential sewers in Milwaukee, WI, as well as from 77 other treatment plants across the US. In Milwaukee, as the wastewater moved from residential sewers to treatment plants, the human-associated bacteria decreased in abundance, and the sewer-associated bacteria increased. The human-associated community varied randomly over time, but the sewer-associated community cycled seasonally with changes in temperature. The wastewater bacterial communities from northern US cities mirrored the Milwaukee communities, while southern cities had distinct community compositions and seasonal patterns..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Presents the basic operating principles and techniques of conventional wastewater treatment processes including preliminary treatment, primary treatment, and secondary treatment, as well as wastewater quality assessment, wastewater collection, and wastewater disposal.

Book for WATER-161: Wastewater Treatment and Disposal II

This course deals with the principles of infrastructure planning in developing countries, with a focus on appropriate and sustainable technologies for water and sanitation. It also incorporates technical, socio-cultural, public health, and economic factors into the planning and design of water and sanitation systems. Upon completion, students will be able to plan simple, yet reliable, water supply and sanitation systems for developing countries that are compatible with local customs and available human and material resources. Graduate and upper division students from any department who are interested in international development at the grassroots level are encouraged to participate in this interdisciplinary subject.

This activity focuses on getting students to think about bacteria, water quality and water treatment processes. Students develop and test their hypotheses about the "cleanliness" of three water samples prepared by the teacher. Then they grow bacteria in Petri dishes from the water samples. They learn how private septic systems and community sewage and wastewater treatment plants work, the consequences to the surrounding environment and wildlife from human wastewater, and what measurements of the released "clean" water are monitored to minimize harm to receiving rivers and lakes.
