Kigali Centralized Sewerage System Project Put on Hold Over Road Disruption Concerns

The construction of Kigali’s first centralized sewerage system, a critical infrastructure project valued at over €96 million, has been halted and sent back to the drawing board. This significant delay stems from the discovery that the original engineering design would have necessitated digging up approximately 80 percent of the city’s existing road network to install pipelines. The Water and Sanitation Corporation (WASAC Group) terminated the initial consultant's contract due to unmet expectations, prompting a comprehensive redesign. This development underscores the complex interplay of urban planning, environmental regulations, and public procurement laws in Rwanda, highlighting the imperative for rigorous due diligence and integrated project planning in large-scale public works.

Kigali, Rwanda's rapidly developing capital, has long grappled with the absence of a comprehensive centralized sewerage system, relying predominantly on septic tanks and pit latrines. The ambitious Kigali Centralized Sewerage System (KCSS) project, initiated to address this critical sanitation and environmental challenge, promised a modern wastewater management solution, including a mega wastewater treatment plant and an extensive pipeline network. However, recent revelations before Parliament's Public Accounts Committee (PAC) have brought the project to an abrupt halt, with the original design deemed unfeasible. Engineers discovered that implementing the proposed 92-kilometer pipeline network would require extensive excavation, disrupting nearly 80 percent of the city's roads. This article delves into the legal and regulatory implications of this significant delay, examining the framework governing infrastructure development in Rwanda and the lessons for legal practitioners involved in such complex public works.

The development and management of water and sanitation services in Rwanda fall under the purview of the Water and Sanitation Corporation (WASAC Group), specifically its subsidiary, WASAC Development, which is mandated with infrastructure development. The sector is governed by a robust legal and policy framework, including the National Water and Sanitation Policy, which harmonizes previous policies and aligns with national development goals and Sustainable Development Goals (SDGs). Key legislation includes Law No. 49/2018 of 13/08/2018 on the use and management of water resources in Rwanda, which addresses quality control, pollution prevention, and wastewater management. The Rwanda Utilities Regulatory Authority (RURA) further establishes regulations governing water supply services and decentralized wastewater treatment systems.

Infrastructure projects in Rwanda are also subject to stringent urban planning and environmental regulations. The Law No. 10/2012 governing urban planning and building in Rwanda, along with the Kigali City Master Plan, provides the framework for structured and sustainable land development. Crucially, all projects likely to have significant environmental impacts are required to undergo an Environmental Impact Assessment (EIA) or Environmental and Social Impact Assessment (ESIA). This is mandated by Law No. 04/2005 (Organic Law determining the modalities of protection, conservation and promotion of environment in Rwanda) and further detailed by Ministerial Order No. 004/2008, which lists projects requiring such assessments. More recently, Ministerial Order No. 003/MoE/25 has expanded the scope to include social safeguards. Public procurement for these projects adheres to principles of transparency, competition, economy, efficiency, fairness, and accountability, as stipulated in Rwanda's public procurement law, with oversight from the Rwanda Public Procurement Authority (RPPA).

The decision to halt the Kigali Centralized Sewerage System project highlights critical failures in the initial design and planning phases. WASAC's Chief Executive Officer, Dr. Asphat Kabaasha, informed lawmakers that the original design for the 92-kilometer pipeline network would have necessitated digging up nearly 80 percent of Kigali's roads, a logistical and economic impossibility. This fundamental flaw led to the termination of the consultant's contract in May, with WASAC citing that the work had not met expectations.

From a contractual perspective, the termination of the consultant's contract raises questions of liability for the flawed design. Such situations often lead to disputes over professional negligence, breach of contract, and potential claims for damages, including costs incurred for the aborted design work and delays. The ongoing discussions between WASAC, the Ministry of Infrastructure (MININFRA), and the Ministry of Finance and Economic Planning (MINECOFIN) on redesigning the project indicate a complex process of re-evaluation and potential re-tendering, which will require careful legal navigation to mitigate further financial exposure and ensure accountability.

The Auditor General's report further revealed that by March 2026, the project's completion deadline had passed, yet only 57 percent of the engineering design had received official approval, despite 90 percent being completed by consultants. This points to deficiencies in project management and oversight, potentially implicating the procurement process itself. Lawmakers questioned why the same contractor involved in the failed assignment had appeared in another procurement process, although WASAC clarified that these were concurrent processes. This scrutiny underscores the importance of robust due diligence in contractor selection and the need for clear contractual provisions regarding performance, deliverables, and remedies for non-compliance within the public procurement framework.

Moreover, the need for redesign necessitates a re-evaluation of the project's environmental and social impact assessments. The original ESIA and Resettlement Action Plan (RAP), which were part of the preparatory work, would need to be revisited to align with any new designs and routes, especially considering the project's potential impact on existing infrastructure and wetland restoration efforts. The delay also brings into focus the integration of urban planning with major infrastructure projects, emphasizing that comprehensive site surveys and coordination with urban master plans are paramount to avoid such costly setbacks.

The indefinite hold on Kigali’s central sewer system project serves as a stark reminder of the critical importance of meticulous planning, comprehensive due diligence, and stringent regulatory compliance in large-scale infrastructure development. For legal practitioners, this case highlights several key implications: the necessity of drafting robust contracts with clear provisions for design liability, change orders, and performance benchmarks; the imperative for thorough pre-contractual investigations, including detailed feasibility studies and site assessments; and the ongoing need for vigilant oversight throughout the project lifecycle to ensure adherence to urban planning, environmental, and public procurement laws.

Moving forward, practitioners should closely monitor the redesign process, the subsequent procurement tenders, and any legal actions or renegotiations arising from the termination of the initial consultant's contract. The manner in which WASAC, MININFRA, and MINECOFIN address the liabilities and re-engage with the market will set precedents for future public-private partnerships and infrastructure projects in Rwanda. This situation underscores that while ambitious development goals are crucial, they must be underpinned by an unwavering commitment to integrated planning and legal prudence to avoid costly delays and ensure sustainable urban development. Legal advisors must guide their clients to prioritize these aspects to navigate the complexities of Rwanda's evolving infrastructure landscape successfully.
