Flooding and landslides which killed 127 people on May 2 and May 3 in Western and Northern provinces affected Gihira water treatment plant in Rubavu district. Some areas in the district experienced water supply disruption after flooding damaged water supply systems and water sources for the treatment plant.
Gihira water treatment plant, which sources water from River Sebeya, produces 23,000 cubic meters per day to four sectors of Gisenyi, Rubavu, Rugerero and Nyamyumba.
However, the plant reportedly loses an average of Rwf20 million every heavy rainy season, according to WASAC.
Two water treatment plants - Kanyabusage and Nyabahanga - also halted operations.
In 2020, the Water and Sanitation Corporation (WASAC) announced that it was going to mobilize financial resources to conduct studies to find out ways of dealing with floods and swashed debris that continues to affect water treatment plants.
Floods have triggered a Rwf4 billion loss after damaging water treatment plants and water supply systems across the country since the start of the year.
