The sewerage projects comprise a basic infrastructure of a nation and are an indisputable indicator of development and civilization. The project pivots greatly around efficient waste water treatment devices to effectively serve the purpose. Such initiatives cater to numerous social needs and aim to improve the quality of life and to protect public health and the environment.
Benefits of Efficient Sewerage System
Water scarcity is increasingly becoming of the greatest threats that the world is currently facing. Thus governments worldwide are developing new projects and technologies to curb its adverse effects. This includes – storm water pits and rainwater harvesting, desalination, water location transfer, and wastewater treatment. A wastewater treatment mechanism receives, stores, treats and disposes of wastewater from all domestic and other sectors.
Reduces wastage
The treatment of wastewater significantly reduces the amount of waste released into the environment. This improves the environment’s health, thereby reducing the health risks associated with poor environmental conditions. Also, it reduces water loss due to water pollution. The process of wastewater treatment minimizes the country’s expenditure on environmental rehabilitation projects required to fight pollution.
Energy Production
The sludge collected during the water treatment process often contains a significant amount of biodegradable material. It is commonly treated with anaerobic bacteria in exclusively designed fully enclosed digesters. On being heated at a certain temperature in the digesters, the anaerobic bacteria can thrive without any oxygen. The gas produced during this process contains a large amount of methane, which is harvested and then burned to generate electricity.
The same electricity can thereafter be used to power the wastewater treatment plant. This makes the factory setup self-sustainable. If an excess of energy is produced, it is transported into the country’s national grid. This helps to lower the reliance on non-renewable energy sources, such as fossil fuels, reducing a country’s carbon footprint and a country’s expenditure on energy production.
On one hand, the water crisis plagues the world while significant public and social resources depend on the sewerage projects of a country. The combination of all the aforementioned benefits along with water production makes wastewater treatment a sustainable short and long-term solution. Thus, treating wastewater becomes an indispensable action to produce clean reusable water.
