A Hopi Native Village in remote northeastern Arizona needed to accommodate a growing population. Land use restrictions required selection of a new community expansion site, but this plot lackied access to utilities. The new site lies a few miles from the existing Lower Moencopi Village. The land is arid and water resources scarce. We evaluated options for alternative energy and appropriate utility technology and phased development strategy, utilizing scarce water resources.
Solar photovoltaic power (PV) was proposed as a scalable off – grid solution for residences. Solar PV with a propane powered electrical generator backup was proposed for the water pumping system. Community development was proposed in phases, comprising dwelling clusters of 20 to match availability of funds. Water wells will be drilled to stay apace with development demand and appropriate sewage treatment also scaled. The Village was also given a planning roadmap, timeline and capital improvement budget for development of a sustainable community.
