Introduction to Active Rainwater Harvesting

This next section of the course (Modules E through E9) deals with various aspects of active rainwater harvesting systems and components, including:

  • Codes, regulations and requirements
  • Site assessment and planning
  • Installation and operation

The current module (E) provides an overview of active rainwater harvesting system components and water quality (Chapter 6 in RH Manual).

Subsequent modules in this portion of the course include: 

  • Module E1: Catchment & Conveyance (chapter 8)
  • Module E2: Pipe & Fittings (chapter 7)
  • Module E3: Debris Filtration & Removal (chapter 9)
  • Module E4: Storage Tanks (chapters 10–12)
  • Module E5: Pumps & Controls (chapter 13)
  • Module E6: Post-tank Filtration & Water Treatment (chapter 14)
  • Module E7: Irrigating with Rainwater (chapter 15)
  • Module E8: Rainwater Harvesting in Extreme Conditions (chapter 16)
  • Module E9: Safety & Quality Control (chapter 17)

Note: the modules in this portion of the course follow the order of the RH Manual, with one exception: Module E1 (chapter 8) comes before Module E2 (chapter 7). This was done to follow the order in which precipitation enters an active rainwater harvesting system: It starts on the catchment surface, before it passes through conveyance, pipe and fittings.

Module Learning Objectives

After successful completion of this module, you should be able to:

  • Explain the many benefits of storing rainwater in tanks
  • Describe the beneficial locations, scales and types of applications to active systems
  • Define key terminology related to active system components
  • Explain elements of Standard 63 that could apply to active system components
  • List the elements of a useful framework for addressing water quality in active system design
  • Identify potential sources of contamination in the air, catchment surface, at the top of the tank, and within the tank
  • Explain processes that offset contamination: treatment trains
  • Identify the components, functions, and characteristics of active rainwater harvesting systems and understand how each component interacts with other components throughout the active system
