From the storage tanks, the water is then gravity fed, no need for pumps, to a series of filters in the Water Organising Module (WOM), see the panel in the picture opposite. This purifies the water in a two stage filtration process to a potable drinking water standard. After this the water is ready for use and is supplied to the sinks and shower. There are also various waste-water treatment systems in place to deal with waste water onsite.
For the Earthship Brighton project the Low Carbon Trust was commended and a finalist in two categories of the Environment Agency's Water Efficiency Awards 2007.
