Clean water is one of the most important things for life. We use it every day to drink, cook, clean, and grow food. But did you know that dirty water can harm us and the environment? When wastewater is released into rivers, lakes, or ponds without cleaning, it pollutes the water we need. This is where sewage treatment plants come in to save the day.
A sewage treatment plant is a system that cleans dirty water. It makes sure harmful things are removed so that the water can be safely reused or sent back to nature. These plants are not just helpful—they are necessary for keeping our water clean and protecting the planet.
What is a Sewage Treatment Plant?
Simply put, a sewage treatment plant (STP) is a place where wastewater—water that comes from toilets, sinks, factories, or households—is cleaned. Before water leaves our homes or industries, it is full of dirt, chemicals, and harmful germs. If this water goes untreated, it can cause serious problems like water pollution, diseases, and harm to plants and animals.
A sewerage treatment plant cleans this dirty water in different steps. By the time the process is done, the water is safe to go back into rivers or be reused for farming, gardening, or even industries.
Why Are Sewage Treatment Plants Important in Bangladesh?
Bangladesh is a growing country with many people, factories, and cities. Every day, we create a lot of wastewater. But, sadly, much of this wastewater is not treated properly. Reports show that only around 40% of urban wastewater is treated, while the rest ends up in rivers or ponds. This makes our water unsafe and dirty.
One example is the Buriganga River in Dhaka. This river used to be clean and full of life. Today, it’s heavily polluted because of untreated sewage and factory waste. Dirty water like this can make people sick and harm fish and other animals.
This pollution leads to:
✔ Health risks: Waterborne diseases like cholera and diarrhea affect thousands of people each year.
✔ Environmental damage: fish and aquatic life die due to toxic waste.
✔ Unsafe drinking water: Many people rely on contaminated rivers and groundwater for daily use.
To protect water sources, we need modern Sewage Treatment Plants (STPs) that effectively clean wastewater before releasing it back into nature. If we want to save our rivers and protect our health, we need more sewage treatment plants.
How Does a Sewage Treatment Plant Work?
Sewage treatment plants use simple steps to clean dirty water. Here’s how they work:
- Removing Big Items: First, things like plastic, paper, or food waste are removed.
- Settling the Solids: In the next step, heavy dirt sinks to the bottom, while oils or grease float to the top and are removed.
- Breaking Down Waste: Helpful bacteria are added to eat the harmful germs and waste in the water.
- Final Cleaning: Extra filters and chemicals are used to remove anything left, like germs or harmful chemicals.
When the water is fully cleaned, it is safe to go back to nature or be reused.

Benefits of Sewerage Treatment Plants
Here are just a few ways sewerage treatment plants help everyone:
- Cleaner Water: Treated water is clean and safe for people, animals, and plants.
- Better Health: Removing harmful germs from wastewater helps stop the spread of diseases.
- Water Recycling: Treated water can be reused, saving precious freshwater for drinking.
- Protecting Nature: Clean water reduces pollution in rivers and lakes, helping fish and plants thrive.
- Supporting Growth: Clean water is important for farming, fishing, and industries to grow.
A Case Study: Dhaka and Other Cities Water Crisis
Bangladesh generates around 2.7 billion liters of wastewater daily, but a significant portion goes untreated. Cities like Dhaka, with over 10 million residents, struggle with inadequate sewer systems.
In Dhaka, untreated wastewater has caused many problems. For example, the Hatirjheel Lake has been polluted by sewage and garbage. It used to be a beautiful place for people to enjoy, but now it struggles with dirty water.
