Hi Remi, can you share a little more information? What sewerage treatment is available in the city? Is there a way of getting waste to any existing treatment location? Is there a particular need for decentralized management of waste? How many users are anticipated per day and are they pour flush toilets with water for washing or something different? Is it a hilly area or quite flat? Do people use groundwater from wells, boreholes or springs for drinking water or other household uses close to where the toilets will be? What is the flooding like? Is it coastal or from a river? How long does the flooding last and are people displaced during that time? Would the toilets themselves flood or would just the planned infiltration area be affected? Any details you can share about the situation can help determine what the options are for sanitation.
