What kind of sewage system?

Comes this question from yesterday’s tour:

HI Michael
Thanks for the tour yesterday, was great to see your systems in action!
I have a quick question about the sewerage which I forgot to ask:
What do you think about composting toilets v. your system for an innner city context such as yours?
Any advice would be appreciated.


My answer:

Great question; thank you.

A composting toilet was not an option on my small inner city terrace site because:

  • it requires a large holding space and, as the bathroom was above the kitchen that would have taken up half the kitchen;
  • to disconnect from mains water and sewer I needed to reuse all waste water to meet the demand for the toilet, clothes washing machine and garden;
  • the house is more marketable with a flushing toilet.


Go well,
