Wastewater Treatment Plants Design and Engineering

IHE Delft Wastewater treatment

Target Audience

This courses focuses on wastewater professionals with background and/or proven qualifications in sanitary engineering, civil engineering, chemical engineering and environmental engineering. Working in the public or private sector dealing with wastewater treatment design.


This course provides the fundamentals for the selection and design of the most appropriate, cost-effective and sustainable wastewater or sanitation treatment system. It also provides the basics on technology selection and costing and engineering economics for the analysis, evaluation and comparison of different treatment alternatives.

Course content

  • Technology selection
  • Costing
  • Engineering economics
  • Engineering process lay-outs and flow diagrams
  • Hydraulic design
  • Design and engineering of activated sludge and anaerobic systems
  • Design and engineering of onsite sanitation systems
  • Design and engineering of land-based systems

Learning Objectives

Upon completion, the participant should be able to:

  • Select the most suitable and cost-effective wastewater treatment process technology to treat certain wastewater stream given its composition and characteristics and taking into account the required effluent standards.
  • Carry out a preliminary design of a wastewater treatment system (based on the most widely applied anaerobic, aerobic, land-based and on-site systems) including the engineering process lay-out, hydraulic profile and process flow-diagram (PFD).
  • Identify and estimate the construction, operational and maintenance costs of a wastewater treatment plant and the investments required to secure its satisfactory operation throughout the expected life-span of the system.
  • Describe the main elements and components involved in the project planning, project management, and project administration for the design, engineering, construction, start-up and operation of a wastewater treatment plant.
