Description:
Information
In accordance with the wastewater amount, population distribution, and characteristics of local topography, there are two types of rural wastewater treatment systems - decentralized system and centralized system. With proper design, construction, operation, and maintenance, both decentralized and centralized wastewater systems can achieve environmental and public health protection.
