Wastewater systems are used for the purpose of collection and disposal of water that is used for household purposes such as bathing, washing clothes, cleaning and also toilet use. The water pipes in your house can be connected to wastewater disposal systems, which recycle water. Mechanical engineering services have come a long way in making systems that can collect water and send it to the recycling process. There are various methods using which wastewater can be managed and recycled. Centralized systems are used in developed towns. In this method, wastewater is transported to a centralized location and then treated for recycling. In the case of decentralized systems, they are sent across to private treatment plants.

Wastewater Management Methods

Wastewater is the water that is usually used in home and business enterprises for various purposes. This damages the quality of water and each building waste lots of water. Wastewater usually contains dirt, waste and other chemicals. This can cause serious harm to the environment and can be hazardous to human beings. Therefore, proper waste management is important to protect public health and save groundwater. Various methods are adopted for doing this and many cities adopt this for effective water management. Recycled water can be used for many purposes such as watering plants, bathing or for irrigation.

One of the important methods of wastewater treatment is the use of bio-solids. These are treated along with wastewater. Wastewater is treated initially once before entering a treatment plant. It goes through physical, chemical and various biological processes to clean and remove any unwanted solids. The wastewater treatment elevates pH levels and removes any odors. This process also sanitizes water by treating it with lime. Any organism such as bacteria, viruses, and other parasites are killed during the process.

Not just wastewater sewer water is also treated and can be recycled. However, recycling sewer water requires lots of advanced systems along with other restoration processes. This might take a very long time to establish. Sometimes to establish these, the sewer system has to be temporarily suspended. This impacts customers as well as businesses. While the project might take a longer time to be completed, it is extremely beneficial once implemented.

Centralized Treatment Systems

These are large scale systems where wastewater from the town or city is collected and treated at a particular place. Usually, these are set up by the town or city’s municipal department that takes care of disposal services for the entire city or town. Centralized systems are much better than decentralized ones. Because, centralized systems are cost-effective, have greater control, require less manpower to manage and easy to monitor. But not on all occasions, these systems can be effective. It is necessary to evaluate this based on the location where this is placed. Another advantage is that they are easier to manage.

Decentralized Treatment Systems

For places such as homes and other buildings which cannot be served by the pubic sewer systems, the decentralized method is used for treating and disposing of wastewater. Most of the wastewater systems are present in the location where it has to be treated. These systems are hence easier to use in rural areas. They are usually a single system and it can serve only a small place where the soil absorption serves an entire division. Since the amount of wastewater treated is small, they require only lesser equipment and investment. They are almost similar to that of centralized ones except that they are on a smaller scale.

One of the important steps in recycling wastewater is introducing it safely into the environment. There are many methods that can be followed for doing this and some of them are: surface water discharge, subsurface, and land application. All these methods can be followed for re-introducing recycled water for everyday use. Sufficient permits and licenses will have to be obtained before doing all these processes. In some cases, they have to be sent via drains so that they can be disposed of safely. Subsurface discharge is the process where the water is treated by sending it into the septic tank to the underground water management system. In some cases, water can be used for purposes such as irrigation.

Wastewater management is not only great, but it also helps in being an eco-friendly option to conserve water and maintain groundwater levels.
