Lead Sustainability Consultants | Sustainability Project Manager | Hybrid Renewable System Architecture Design | Green Building Accredited Professional (Green Star SA Net Zero Carbon certification management)
Two Dam Sustainable, a trout farm near Montagu, Western Cape, is one of the first four pilot projects to have been certified net zero in South Africa in October 2017. As the sustainability consultant on the project, Ecolution worked closely with the farm as the sustainability project manager, and were appointed as the Commissioning authority that certified the farm net zero under the GBCSA’s Green Star SA Net Zero Carbon certification.
Operating as an off-grid, responsibly operated trout farm, it produces ethically made trout products and runs almost entirely off of renewable energy. The majority of the energy used for the farm is provided by a 31 kW photovoltaic panel array and a ‘high pressure, low water volume’ micro-hydro turbine that generates up to 1kW of continuous electricity.
The farm is home to a hyper-efficient Recirculating Aquaculture System (RAS) – which is the first of its kind in Africa. The Rainbow Trout RAS operates sustainably by being an energy efficient low head recirculating system which requires comparatively low electricity as opposed to conventional high pressure RAS or high volume raceway cultures, which require and often pollute huge volumes of fresh water.
