Wastewater treatment is a process by which we mechanically, biologically and chemically purify already used water. For the time being, we have a mechanical and biological degree of purification at the Zagreb plant. Most of that water that comes to the purifier is previously used in our homes, industry and companies that have waste, and must be treated before we release it into the environment. The benefits of clean water and the importance of wastewater treatment plants in a city can be felt in these summer months, when many of us find refreshment in the river and the sea.
Properly treated wastewater contributes to a cleaner environment and gives us satisfaction during the holidays.
If the term “wastewater treatment” confuses you, we could also say “sewage treatment”. Nature has an amazing ability to deal with small amounts of aquatic waste and pollution, but it would be overcome if we didn’t treat the billions of gallons of wastewater and wastewater that are generated every day before we release them back into the environment. Wastewater treatment plants reduce pollutants in wastewater to a manageable level.
Wastewater also includes rainwater and road flushing water. While some people assume that the rain that flows down the street during a storm is pretty clean, it isn’t! Harmful substances that are created during the washing of roads, parking lots and roofs can be very harmful to our rivers and lakes.
Why treat wastewater?
It is a matter of caring for your environment and your health. There are many good reasons why keeping water clean is an important priority:
CLEANER RIVER AND SEA: By returning purified water to the sea and the river, we protect the eco-zone of that city and we can enjoy its benefits.
FISHERIES: Clean water is crucial for plants and animals that live in water. This is important for fishing, sport fishing enthusiasts and future generations. It is a well-known fact that some forgotten animal and plant species returned to the Sava River after the treatment plant was built.
WILDLIFE HABITATS: Our rivers and ocean waters abound with life that depends on the coast, beaches and swamps. They are critical habitats for hundreds of species of fish and other aquatic animals. Migratory waterfowl use the rest and feeding areas.
RECREATION AND QUALITY OF LIFE: Water is a great playground for all of us. The picturesque and recreational values of our waters are the reasons why many people choose to live where they live. Visitors are attracted by water activities such as swimming, fishing, boating and excursions.
HEALTH CARE: If non-wastewater is not treated properly, it can also be a carrier of disease. Because we live, work, and play so close to water, we need to remove harmful bacteria to keep water safe for everyone.
