In his address, delivered on behalf of the Prime Minister, Mr. Traoré emphasized that this project addresses an urgent need: strengthening sludge treatment capacity from septic tanks, as the Kossodo and Zagtouli plants are now insufficient to meet the growing demand.

For the Prime Minister, this new infrastructure embodies:

The commitment to ensuring universal access to safe sanitation by 2030

Contribution to a circular economy through the valorization of sludge as organic fertilizer

Mr. Traoré also stressed the shared responsibility of citizens and sanitation companies, urging households to:

Recognize that investing in latrines is investing in health and dignity

He further demanded impeccable professionalism from the companies tasked with operating the plant, noting that no shortcomings would be tolerated given the substantial financial investment by the state.

The Komsilga plant, scheduled to begin operations on September 30, 2026, was financed with 4.5 billion yuan.
