I am doing a master's degree in environmental policy, and I have two upcoming assignments that require that I trace and analyse my solid waste and the type of running water I get (is it treated? If so, with what? Where does the wastewater go? Is it discharged into a collection system? If so, what type of collection system? Is it treated beforehand and with what? If it's treated, is it used in agriculture/ industry as grey water? What happens to the sludge after it leaves the wastewater treatment plant? etc). If there are any people out there familiar with wastewater treatment and/or solid waste treatment in Istanbul, I would be eternally grateful if I could have a chat with you. Thanks in advance.
