This method is effective in reducing pollution but requires Efficient wastewate r Reduces Advantages: treatment. environme ntal High contamina 3. Septic installation Disadvant tion. Tanks and ages: Requires maintenan space and ce costs. proper soil conditions 4. Composted Pit Latrine Composted pit latrines use aerobic decomposition to break down waste. The design allows for the collection of organic waste, which is then composted and can be used as fertilizer. This method promotes recycling Produces compost that 4. Composted Pit Latrine can be used in agriculture. Advantages: Reduces environmental impact. Requires management Disadvantages: and knowledge of composting. Not suitable for all climates 5.
