Lake Nokoué – Ganvié: Wastewater Treatment Plant (Water Hyacinth)

Lake Nokoué – Ganvié: Wastewater Treatment Plant

The town does not have a wastewater treatment facility. Wastewater from cleaning and bathing as well as human and animal waste go directly into the lake. The plant in the foreground, water hyacinth, helps purify the water and keep it healthy for fish and other life. According to NASA research, “Water hyacinths thrive on sewage; they absorb and digest wastewater pollutants, converting sewage effluents to relatively clean water.”

    Just watch out for the water hyacinth. It is feloniously renewable, and will quickly dominate the lake. It can be harvested and made into biofuel, biochar and fertilizer. Its fiber can be made into furniture or clothing.
