The Together Association designs and installs low-cost community sewage and water treatment systems, providing potable water in homes and water for irrigation. The village-wide sewage system connects household septic tanks by gravity-fed pipes to a communal filtering facility, where trained community technicians oversee maintenance and quality control. The sewage system model is built and maintained with locally available materials and labour, making it 70-75% cheaper than government-issued systems. To date four villages in Upper Egypt have been connected to the Together Association sewage systems, with a total of 37,000 direct beneficiaries who now receive proper in-home sanitation services.
