Ryton Gardens has existing facilities for rainwater harvesting, although the condition of these underground tanks is not known; this happens via the roofs of two of the main buildings on-site. Despite this, the water usage far outweighs the water recycling of the site.
Adventist Arc sought to incorporate aquaponics – a farming method that uses 90% less water than traditional agricultural methods – into the Ryton Gardens site.  This farming method also provides two lines of produce, both fish and crops. 

In order to meet and carry out this intention, we sought to recycle the grey water from hand washing of the 30-60 employees on the site, and also use rainwater collection methods; both sources of water will need to be filtered before being injected into the aquaponics cycle. Our calculations have determined that the handwashing water alone accumulates to over 1000 litres per day on the site. Solar panels will be incorporated to generate the energy needed to power the pumps that circulate the water from the fish, to the plants, and back again.

Surplus vegetables grown in the aquaponics system (e.g. peas), will be blanched, chopped, and fed to the fish, and since the fish waste feeds the plants, this truly will be a closed-loop cycle. Water is the thing that fuels Ryton Gardens; however, the only place where water is annouced is the carpark, when it floods. We envisage this intervention being a celebration of water - opportunities of which can be via water filtration and purification, turning the greywater into purified water, fit for the aquaponics cycle. A swale system purifies all of the site's waste and injects the purified water into the aquaponics system, encouraging biodiversity. The scheme also incorporates Hydotherapy zones, which uses water from the swale system that is further purified for human use.
