Havana Solar Aquatics System

The Pogolotti Solar Aquatics System, Urban Garden (Organiponico) and Food Forest was designed and built in Havana, Cuba and funded by the Canadian International Development agency (CIDA). The idea sprouted from the great forward strides of Cuba to feed itself through the development of urban agriculture.  With a growing drought affecting the country and a shallow often polluted aquifer, the limitations for urban agriculture seemed pressing.  Our concept was to reclaim wastewater using decentralized treatment approaches. Urban sewage collection systems in Havana flow by gravity to outfalls and then into the creeks and rivers of the Havana Metropolitan Park. The decentralized concept is very applicable in this case and in many other cities. Next step was to design and construct a shadehouse for a Solar Aquatics System technology.  The goal was to clean the wastewater to a high level leaving the dissolved phosphorus and nitrate nutrients in the water. This reclaimed water would then be made available to nearby urban farms to assist the development of food forests and “organiponico” urban gardens throughout Cuban cities.
