The design of a wastewater treatment plant involves studies on the ground, including the population and its needs, projections on the flow of water and availability of resources, infrastructure and water treatment systems to be used, whether it is a question of a plant for use in industry, agriculture or urban uses.
The primary part of taking into account is the composition of the wastewater, whether it comes from human, agricultural or industrial use. In each case, the composition of the water will be different, which implies different models of treatment and operation of the plant. A significant element to consider is the attendance of organic waste, household items such as soaps or solid material, and the presence of substances that could prevent the growth of bacteria for biological treatment, such as pesticides, chemicals or poisons.

The composition of the wastewater is key to the design of the wastewater treatment plant and determines the system that will be used. For most plants, the water will contain human waste from cities, so biological treatment with the anaerobic system will be essential.
Another issue to consider is the amount of decontamination to be achieved with the processes, which depends on the uses that will be given to the final product. In the case of water intended for agricultural use, no higher levels of purification are needed, and even the presence of organic components could be favorable. In urban waste, the processes can be mainly biological, with the use of activated sludge, a system by which different types of aerobic bacteria make the substances suspended in the water acquire greater volume, which allows their sedimentation at the bottom of the water—purification vats.
The management of the environment is one of the determining factors in the design of a wastewater treatment plant. The possibility of having tributaries and the distance at which the plant is with respect to urban or agricultural areas, as well as clean water courses.
