Wastewater Management: A New Way Ahead

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 waste water 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 waste water can be managed and recycled. Centralized systems are used in developed towns. In this method, waste water is transported to a centralized location and then treated for recycling. In case of de-centralized systems, they are sent across to private treatment plants.

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 wastes 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 ground water. 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 waste water 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 odours. This process also sanitizes water by treating it with lime. Any organisms 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 take 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 in 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, decentralized method is used for treating and disposing 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 waste water 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, it helps in being an eco-friendly option to conserve water and maintain ground water levels.
