Calcamite’s Econo 5 400L septic tank (digester) is the only septic tank in the market with an inner septic baffle which creates a double chamber in the tank. Our septic tanks come with a 50mm outlet with a lid. The 5 400L septic tank has the capacity to process up to 20-25 people’s septic waste. The septic tanks utilises anaerobic microbial action to convert solids to black water or effluent.
