Kigali’s smart waste and rainwater harvesting project delivers early wins 

Kigali’s efforts to modernize waste management and provide backup water in the neighborhoods of Busanza and Mpazi are showing results.

Cleaner streets, on-time collection 

Waste services are running smoothly, with Busanza residents hitting 100 percent compliance in separating trash, and Mpazi close behind at 93 percent. The gap in Mpazi stems mainly from newcomers who haven’t yet received bins. Still, waste is being dropped off at the right collection points, and no delays in pickup have been reported. Local meetings and neighbor-to-neighbor learning are helping new households adapt quickly. 

Rainwater harvesting brings relief 

The rainwater harvesting system has proved its worth as both a backup source during shortages and a supplement to piped water. 

  • In Mpazi, 94 households relied on harvested rainwater for two weeks in June when the piped supply ran dry. Most used modest amounts, though limited tank charging meant reserves ran out quickly. High tenant turnover also makes upkeep a challenge. 
     
  • In Busanza, 228 households used rainwater alongside piped water for nearly a month. Most drew only small amounts, showing their role as a helpful supplement. Busanza’s higher share of owner-occupiers has also encouraged better care of the systems. 

Why it matters 

For residents, the project is more than numbers: it means streets are cleaner, waste is collected on time, and families have an extra lifeline when taps run dry. If the fixes now underway succeed, Kigali could soon have a scalable model for other fast-growing urban neighborhoods facing the twin pressures of waste and water insecurity.
