Design of Sedimentation Tank

An infectious unit of a hospital has 6 beds and 4 nurses caring for the patients. Assuming each of them use 150 litres per day. You are asked to design a treatment tank to handle the solid waste and the contaminated water from the infections brought into the sedimentation tanks. What parameters will you require to design the tank to take care of the solid waste. Assuming the water in the last chamber will be pumped once every 3 months.
