What Departamento Municipal de Água e Esgoto does

Departamento Municipal de Água e Esgoto (DEMAE) is a municipal autarchy (Autarquia da Administração Indireta) of the Prefeitura Municipal de Campo Belo, Minas Gerais, Brazil, established on 6 November 1967 under Lei nº 737. It holds an exclusive concession to operate, maintain, and exploit public water supply and sanitary sewage services throughout the municipality of Campo Belo. The utility operates one Water Treatment Station (ETA Tolica plus ETA Norte), 24 artesian wells, and a distribution pipeline network including the Reservatório da Campos Sales originally constructed with iron tubes in the 1960s. Service coverage spans residential, commercial, industrial, public/government, social (subsidized for vulnerable populations), and rural customer categories, with mandatory connection within municipal boundaries.

DEMAE's revenue model is governed by Lei Complementar Nº 76 of 10 December 2008, which established tiered usage-based water tariffs (R$ 1.58/m³ rural up to R$ 9.03/m³ industrial, plus flat minimums ranging from R$ 9.56 social to R$ 66.25 industrial for 0-10m³) and sewage charges set at 50% of water rates. Supplementary revenue includes one-time connection fees (R$ 92.69-R$ 349.62), meter calibration (R$ 51.50), water analysis (R$ 197.83), and fines for illegal connections. Bills are issued monthly and collected through a multi-bank network (Banco do Brasil, Itaú, Bradesco, Santander, Mercantil, SICOOB COPERMEC, Cooperativa de Crédito Regional Campo Belo), lottery outlets, authorized retailers (Abel Móveis, Papelaria Pitágoras), and direct debit.

The organization employs 51-100 staff, maintains a Transparency Portal in compliance with Brazilian federal law (Lei Complementar Federal 131/2009, Lei Federal 12.527/2011), publishes water quality analysis reports, follows e-MAG accessibility guidelines (Decreto 5.296/2004), and operates an electronic procurement portal. Customer service is delivered via 0800 hotline, WhatsApp, and in-person at its headquarters at Av. 7 de Setembro, 363 - Centro, Campo Belo/MG. As a government monopoly utility, DEMAE has no direct private-sector competitors within its service area and is directed by a Director appointed by the Municipal Mayor.

Broad incumbents

• Sanepar (Companhia de Saneamento do Paraná): State-level water and sewage utility in Paraná with similar integrated water treatment, distribution, and sewage operations. Listed entity providing benchmark financial disclosure for the sector that DEMAE operates in.
• Cagece (Companhia de Água e Esgoto do Ceará): State-level water and sewage utility in Ceará with comparable service scope (water treatment, distribution, sewage collection, customer billing) to DEMAE, but operating at state scale across multiple municipalities.
• SABESP (Companhia de Saneamento Básico do Estado de São Paulo): Brazil's largest water and sewage utility, serving over 28 million people in São Paulo state. Provides identical potable water and sanitary sewage services to municipalities under concession contracts, representing the upper-bound scale peer for any Brazilian water utility.
• CAERN (Companhia de Águas e Esgotos do Rio Grande do Norte): Smaller Brazilian state-level water and sewage utility with comparable integrated service model to DEMAE, recently privatized — providing structural insight into the trajectory from municipal/state autarchy to private operator.
• Embasa (Empresa Baiana de Águas e Saneamento): Bahia state water and sewage utility offering the same integrated water supply, treatment, and wastewater service model as DEMAE across hundreds of municipalities, with mixed public ownership.
• COPASA (Companhia de Saneamento de Minas Gerais): State-level water and sewage utility serving hundreds of municipalities across Minas Gerais. Operates the same core services (water treatment, distribution, sewage collection) as DEMAE but at vastly greater scale and with private-sector minority ownership.
• Corsan (Companhia Riograndense de Saneamento): Rio Grande do Sul state water and sewage utility operating the same end-to-end water and wastewater service model as DEMAE across hundreds of municipalities, currently undergoing privatization — a relevant structural comparison for a Brazilian municipal water autarchy.
• Casan (Companhia Catarinense de Águas e Saneamento): Santa Catarina state water and sewage utility operating the same end-to-end water treatment, distribution, and sewage collection model as DEMAE across multiple municipalities, providing a relevant scale-comparable peer.

Emerging players

• Aegea Saneamento: Private-sector water and sewage operator holding concessions in multiple Brazilian states. Directly comparable to DEMAE in service offering but represents the private-operator alternative model for Brazilian municipal water provision.

Regional players

• Águas de Manaus ( concession of Águas do Brasil): Concession-operated water and sewage utility serving Manaus under a private-operator model. Demonstrates the alternative concession structure (vs. DEMAE's municipal autarchy) for Brazilian water service delivery at municipal scale.
