The primary feature of this technique for waterharvesting is a 'dry
creekbed'. This is a bed of rocks, gravels, sands and soils which can be
sealed from, seeping into, or open to the landscape profile.
A system of subsurface creekbeds is used to direct stormwater and
greywater or any wastefluid to landscape growing areas, while at the
same time filtering and treating the water to remove contaminants and
then recycling the treated water for non potable uses.
