Submission: "The Clean Hub "

A self contained, self reliant, manufactured structure to supply clean water, electricity, and sanitary facilities for hundreds of people for 30 years or mor

APPLICATIONS

DISASTER RECOVERY/REBUILDING
The Clean Hub has the capacity to serve as a long term solution to disaster recovery and rebuilding by providing clean water and electricity in areas that lose their existing infrastructure due to war, natural or other disasters.  In areas such as Sri Lanka where land disputes are brought about from lost infrastructure, the outhouse can serve to mitigate these problems and make the rebuilding process safer, faster, sustainable, and economical.

URBAN SLUM UPGRADING
About 1/3 of the world's population lives in an urban slum.  The culture of slums provides a great contribution to cities as a labor force, artistic expression and countless other ways. The survival of  the over 2 billion slum inhabitants is, therefore, crucial to our world economically and culturally.  The Clean Hub is able to weave into dense urban fabric and provide infrastructure in places too difficult for conventional means.

REMOTE / REFUGEE FACILITIES
While rural or remote villages are very adept at being self sustaining, some of their basic resources are in jeopardy as the world grows around them.  Some villages have lost their water supply to contamination by industries.  Other villages have been forcibly relocated. The Clean Hub provides a self contained means of sustaining these people's lives.  The Out House can provide this same function within refugee camps for as long a time as is needed and can be left behind for new settlements to build around.

RELIEF HOUSING
In developed countries, the Clean Hub can serve as relief housing for those displaced by war, natural or other disasters.  It can also serve as a tool for disaster preparedness

COMPONENTS

ROOF STRUCTURE
The roof is constructed of light gauge metal with metal roofing and an integral rain trough.  The solar side is adjustable for pitch to utilize local sun angles.

SOLAR ARRAY
Attached to the roof, the outhouse can support up to 16 photovoltaic panels.  The system is scalable to accommodate areas where electricity is not needed.  In areas of extreme need, the Clean Hub can generate up to 2,640 watts of peak power.

SHELL
The main shell is constructed of stress skin panels mechanically fastened on site.  Ventilation occurs through the roof panels.  The end walls are made of two impact resistant triple wall polycarbonate panels.  There are two secure entries on either side and two interior secure entries to the mechanical space.

WATER SYSTEM
A reverse osmosis water system is located in the mechanical space and pumps water from the reservoir which is stored beneath the shell and below grade to regulate the water's temperature.  The reservoir collects water actively and passively.  It can be tapped into an existing water source or fed water.  The RO system is designed to handle brackish, salt, or otherwise contaminated water.  The showers and sinks both return grey water back to the reservoir as well.  The toilets are waterless and self composting.

FOUNDATION
The foundation is constructed of four helical piers which allow for unstable, uneven, flooded or contaminated land while providing security.
