Which of the following is a drawback of having catchment system components to produce both potable and non-potable rainwater for in-house reuse?
  1. Greater flexibility in reuse
  2. Requires additional permitting and code compliance
  3. Requires two plumbing systems
  4. Cannot tell which is potable and which is non-potable
Explanation
Answer: C - In order to transport treated potable rainwater (for drinking and cooking) and non-potable rainwater (for toilet-flushing and bathing) into the house, the homeowner must have two plumbing systems from the catchment system into the house. This adds complexity, space usage and expense. Most jurisdictions require no permitting or code compliance for rainwater catchment systems.
