- Activity: Collection of rainwater for potable residential water supply.
The Do/Peters-Do family residence is located just south of Austin in an area with marginal groundwater supplies. Due to poor quality of the groundwater that supplied their home and with the goal of long-term water security, the Do/Peters-Do family decided to invest in a rainwater harvesting system as the primary potable water supply for their home. The utilization of harvested rainwater as the primary potable water supply makes this residence unique. Also unique is the structure itself – the exterior walls are 24” thick, utilizing over 160 tons of adobe cob mixture to minimize the home’s energy needs.
