- A rainwater collection system at Rosalie captures all rainwater on the
main roof and diverts it into a large 3000 gallon tank, which then services all six toilets and the washing machine in the house. A similar system will be installed at Ruth.
- All showers are equipped with low-flow 1.5 GPM showerheads, many of the toilets have dual flush handles, and all of the sinks have low-flow aerators.
- All of the air conditioning condensate (approximately 10 gallons per day in the Houston TX summer) is diverted to the garden and fruit trees for automatic watering.
