Companhia de Saneamento do Amazonas

What Companhia de Saneamento do Amazonas does

Companhia de Saneamento do Amazonas (COSAMA) is a state-owned water and basic sanitation utility (empresa pública) of Amazonas state, Brazil, established by Lei n.º 892/1969 and wholly owned by the Government of Amazonas. Its core operations consist of water capture, treatment, and distribution for human consumption across 15 interior municipalities of Amazonas state, serving residential consumers and municipal governments under a regulated tariff structure (Estrutura Tarifária). The company's physical footprint comprises 15 agency locations distributed across remote riverine communities in the Amazon interior, with administrative headquarters in Manaus.

COSAMA's underlying technology stack is conventional municipal water utility infrastructure — water treatment and distribution systems — supplemented by digital customer-facing channels. These include the Agência Virtual web portal (cosama.contaseconsumo.com.br) for bill payment, consumption history, and debt management, and the Mais Água mobile application available on Google Play and App Store for account self-service. The company does not disclose APIs, SDKs, proprietary software platforms, or AI/ML capabilities.

The business model is a regulated subscription/recurring revenue model based on water and sanitation tariffs charged to residential and municipal consumers across its 15-municipality service territory. Operations are also supplemented by government allocations from the Government of Amazonas. The go-to-market is sales-led and direct-service in nature: customers access services through physical agencies, the virtual portal, the mobile app, or customer service channels (SAC, Ouvidoria). Total employee count is approximately 702 per employee-records data (with a conflicting firmographic figure of 81), and the company is not publicly traded, with no external investors, funding rounds, M&A activity, or partnerships disclosed in the source material.
