What you will learn

This course explores the technicalities, design and implementation of reedbeds and alternative waste water treatment systems at a domestic level.

You’ll learn about the various options for low impact sewage treatment systems and nutrient recovery, and there will be a session on water efficient devices.
CAT is completely off-grid for water supply and sewage treatment, so you’ll have a chance to see reedbeds and waste water management methods in action, with a tour of our various systems and an explanation of the main design features. We will also cover some unique and bespoke alternatives.

Topics covered include:

• Primary, secondary and tertiary treatment
• Types of systems, including reedbeds, constructed wetlands, trench arches, aquatrons and greywater treatment
• Biological processes
• Main design aspects and maintenance requirements
• Location, regulations and planning

Participants will understand the theory and practical application of various types of alternative waste water treatment systems in the UK, the main design features and the most appropriate
application.
