Various aspects to be considered in the design of a treatment plant include :

Characteristics of the wastewater in terms of quantity, quality Presence of toxicants/ biological inhibitors ( in case of a biological treatment plant) Wastewater discharge pattern ( Continuous/ intermittent/ batch dump/ peaking factors/ seasonal variations) Locational and environmental factors ( Altitude, Temperature variations, rainfall etc) Selection of appropriate Technology, treatment units and treatment Processes Etc

Engineering aspects of a plant are related to :

Proper and optimal layout of plant Proper and optimal hydraulic levels and level differences of various units in the plant Proper selection of mechanical equipments such as capacity/ rating etc.
