ALUVIA RESPONSE · KIGALI SANITATION

Can decentralised sewer systems solve Kigali’s sanitation challenges?

A New Times report asks whether decentralised sewer systems can help Kigali. ALUVIA’s answer is yes—when decentralisation means real treatment, professional commissioning, mandatory maintenance and verified outlet quality, not simply another holding tank.

ALUVIA decentralised wastewater treatment integrated into a building site in Rwanda

The missing scale between a septic tank and a city sewer

Kigali’s buildings and premises do not all have the same occupancy, wastewater load, topography or receiving environment. Waiting for one network to reach every site leaves owners with overflow, odor, repeated emptying and uncertain performance. A building-level DEWAT system creates an implementable layer between individual containment and future city infrastructure.

How ALUVIA integrates into Rwanda’s buildings and premises

ALUVIA ECOFLOW is designed for integration across restaurants, offices, hotels, schools, healthcare premises, residential developments and commercial buildings, subject to project assessment. It can be installed in an existing or requested concrete setup, in PE tanks at surface or below ground, or as a fully containerized, plug-and-play DEWAT system from 100 PE.

A standard range, configured for the site

Decentralised must still mean accountable

Every system needs an identified owner, an operating plan, a maintenance budget, sampling access, laboratory verification and records. ALUVIA therefore makes maintenance mandatory. ALUVIAMEDIA biological activation starts from commissioning and the selected ALUVIA Care plan supports continuity throughout operation.

From nuisance to a managed resource

Correctly treated and verified water may be considered for approved non-potable uses such as garden irrigation, washing and cleaning. The permitted route and numerical limits depend on the project and authority approval. This turns wastewater planning from emergency truck logistics into measured infrastructure.

ALUVIA’s practical proposal for Rwanda

Assess each building or premises, select the standard ECOFLOW capacity, integrate it into the site, commission it under representative use, verify performance and maintain it professionally. Existing installations receive a free initial on-site assessment.
