Wendy - Where Does Our Wastewater Go?

Everybody talks about water conservation and the importance of saving water, but rarely do we discuss what happens to wastewater after it goes down the drain. Have you ever wondered where does our wastewater go? What happens to it once it leaves our homes and businesses? In this article, we will explore the journey of wastewater and shed light on its treatment process and eventual destination.

The Wastewater Journey Begins

Once we flush the toilet or let water slip down the sink, our wastewater embarks on a journey through a complex system of pipes and treatment plants. It starts with the collection process, where gravity and pumping systems guide the wastewater towards the treatment facilities. These facilities, also known as sewer plants, are specifically designed to handle and treat wastewater effectively.

The Treatment Process

Once inside the treatment plant, the wastewater goes through several stages of treatment to remove impurities and harmful substances. The first step is screening, where large debris and solids are filtered out. Afterward, the wastewater enters a settlement tank, also known as a clarifier, where smaller particles and organic matter settle to the bottom. The remaining liquid, known as effluent, passes through to the next stage.

In the secondary treatment process, bacteria are introduced to the effluent to break down organic matter further. This is done in aerobic conditions where the bacteria consume the organic material, converting it into carbon dioxide and water. This stage greatly reduces the biological oxygen demand (BOD) of the wastewater, making it less harmful to the environment.

The final step is tertiary treatment, which involves the removal of any remaining impurities, including dissolved nutrients and microorganisms. Various methods like filtration, disinfection, and chemical treatment are employed at this stage to achieve the desired water quality standards. Once the treatment process is complete, the reclaimed water can be safely discharged or reused for non-potable purposes such as irrigation or industrial processes.

The Destination of Our Wastewater

So, where does our wastewater go after it has been treated? Depending on the location, regulations, and specific needs, the treated wastewater undergoes different journeys. In many cases, it is discharged into nearby rivers, lakes, or oceans, where further dilution occurs, allowing the ecosystem to naturally process any remaining impurities. This ensures that the discharged water does not pose a threat to aquatic life or the environment.

Additionally, some treated wastewater is utilized in environmental restoration projects. For instance, it can be redirected to replenish wetlands or recharge groundwater aquifers. Reclaimed water is also increasingly being used for agricultural purposes, reducing the reliance on freshwater resources for irrigation. In some areas, advanced treatment techniques even allow reclaimed water to be potable, providing a sustainable and alternative water supply.

The journey of wastewater is an intricate process that involves careful treatment and management. We must recognize the importance of wastewater treatment in preserving our environment and conserving water resources. Understanding where our wastewater goes and how it is treated empowers us to take informed actions towards water conservation and sustainable practices. Let's appreciate the efforts made by wastewater treatment plants and embrace the value of wastewater as a valuable resource.

Wendy, Where Does Our Wastewater Go? takes students on a fun and informative tour of the wastewater treatment process at their local plant. Wendy and her companions learn where wastewater goes and how it is treated in Washington, DC.

This book is aimed at elementary school students, ages 6 – 12 but can be eye-opening to an array of students and parents, too. Educators can use this resource to add a new twist to environmental holidays as well as inform students about how to expand their pollution reduction goals to the collection system and overall health of their local waterways.
