Art Ludwig was hired by Huehuetortuga, a new landholding added to the ecological arts community of Huehuecoyotl, to intertwine water, wastewater, energy systems and landscaping in a diverse and extreme environment at 7000 feet elevation with an average annual rainfall of four feet eight inches, and no rain for eight months. The development has no water supply during the dry season, water is either stored or brought in by truck. To maximize water use and insure water independence through the dry season, the site now includes rainwater harvesting, surface water diversion, efficient fixtures, four greywater systems, constructed wetland, edible landscaping, a composting toilet, solar hot water, and hydro-electric power.
