The Rwandan government's Water and Sanitation Corporation (WASAC) is re-tendering a crucial waste treatment and landfill project in Rubavu, financed by the African Development Bank, following significant delays and poor execution by the initial contractor. This setback highlights challenges in infrastructure development but also the commitment to ensuring proper sanitation facilities …
Imagine your town needs a special factory to clean up all the dirty water and trash so everyone stays healthy. Rwanda started building one in a town called Rubavu, but the first builder didn't do a good job and was too slow. So, the government agency in charge, WASAC, fired them and is now looking for a new, better builder to finish the job quickly, hopefully in about 16 months, so the town can have clean water and a proper place for trash.
Analysis
Rubavu Waste Treatment
The Rubavu faecal sludge treatment plant and landfill project, initially budgeted at Rwf4.1 billion, has faced significant delays, leading to the termination of its initial contract. This vital infrastructure initiative, part of the Rwanda Sustainable Water Supply and Sanitation Programme, aims to address human waste and solid waste disposal in Rubavu Town. The project's stalled progress underscores the complexities inherent in large-scale public works, particularly when contractor performance falls short of expectations.
Despite an allocation of Rwf1.1 billion in the 2025/26 fiscal year, only 6.4 percent of these funds were utilized by the time of the Auditor General's inspection. This severe underperformance necessitated the contract's termination on May 8, 2026. The government has since allocated Rwf542.9 million for the 2026/27 fiscal year to facilitate the restart of works, demonstrating a continued commitment to the project's completion. The new contractor will be tasked with completing the facility, which is designed to treat 45.7 cubic metres of faecal sludge and handle 35.9 tonnes of non-organic solid waste daily, alongside a composting facility.
WASAC Development Ltd
WASAC Development Ltd, the implementing agency, is now spearheading a new procurement process to secure a competent contractor for the Rubavu project. This involves a mandatory site visit for prospective bidders on September 30, followed by an optional online pre-bid meeting on October 2, to ensure clarity on the scope of work and tender requirements. The rigorous process, including a requirement for a $20,000 bid security, aims to prevent a recurrence of the previous contractor's poor performance.
The deadline for bid submissions is set for October 27, with an ambitious completion timeline of 16 calendar months once the new contract is awarded. This expedited schedule reflects the urgency placed on delivering essential sanitation services to Rubavu residents. WASAC's proactive approach in terminating underperforming contracts and initiating new tenders highlights a commitment to accountability and efficient project delivery within Rwanda's infrastructure development landscape.
Kigali Sanitation Projects
Beyond Rubavu, Rwanda is undertaking several other significant sanitation projects, particularly in its capital, Kigali. Phase I of the Kigali Centralised Sewerage System, which received Rwf3.5 billion in 2025/26, also experienced delays due to poor contractor performance, leading to contract termination in May 2026. This parallel issue suggests systemic challenges in contractor selection or oversight across multiple critical projects.
The Masaka faecal sludge treatment plant in Kigali is nearing completion, at about 90 percent, though it faced delays due to electricity connection issues. The overall Kigali faecal sludge treatment plant has a substantial budget of Rwf14.38 billion through 2028. Furthermore, the Kigali Municipal Solid Waste Management Facilities project, including the Nduba sanitary landfill, is budgeted at Rwf45.03 billion through 2028, with significant allocations for design, construction, upgrading, and operational management. These extensive investments underscore Rwanda's comprehensive strategy to enhance urban sanitation and waste management infrastructure.
Key points
- WASAC Development Ltd is seeking a new contractor for the Rubavu waste treatment plant and landfill project.
- The previous Rwf4.1 billion contract was terminated due to poor performance and significant delays.
- The project, part of the Rwanda Sustainable Water Supply and Sanitation Programme, is financed by the African Development Bank.
- New works are expected to be completed within 16 calendar months, with bids due by October 27.
- Similar contractor performance issues have affected Phase I of the Kigali Centralised Sewerage System.
The swift termination of the underperforming contract and the launch of a new procurement process demonstrate Rwanda's commitment to accountability and efficient project delivery. A successful re-tendering and completion of the Rubavu project within the 16-month timeline would significantly improve public health and environmental conditions in the region, setting a positive precedent for future infrastructure developments.
The repeated issues with contractor performance, as seen in both Rubavu and Kigali's sewerage system, suggest potential underlying challenges in project oversight or contractor vetting. There's a risk that the new procurement process could face further delays, or the selected contractor might also underperform, prolonging the lack of essential sanitation services and increasing overall project costs.
