Brief Description
Wastewater is used water. We are going to see how to treat water and what can help us.


What is wastewater?

• Wastewater is used water. It includes substances such as human waste, food scraps, oils, soaps and chemicals. In homes, this includes water from sinks, showers, bathtubs, toilets, washing machines and dishwashers. Businesses and industries also contribute their share of used water that must be cleaned.

• Wastewater also includes storm runoff. Although some people assume that the rain that runs down the street during a storm is fairly clean, it isn't. Harmful substances that wash off roads, parking lots, and rooKops can harm our rivers and lakes.


Why Treat Wastewater?

It's a maLer of caring for our environment and for our own health. There are a lot of good reasons why keeping our water clean is an important priority:

• Fisheries

Clean water is criOcal to plants and animals that live in water. This is important to the fishing industry, sport fishing enthusiasts, and future generations.

• Wildlife Habitats

Our rivers and ocean waters teem with life that depends on shoreline, beaches and marshes. They are critical habitats for hundreds of species of fish and other aquatic life. Migratory water birds use the areas for resting and feeding.

• Health Concerns

If it is not properly cleaned, water can carry disease. Since we live, work and play so close to water, harmful bacteria have to be removed to make water safe.

What happens if you treat water wrong?
