Aegea reduces disease rate in Campo Grande with universal sanitation programs
With the help of Águas Guariroba programs, Campo Grande should be one of the first Brazilian capitals to achieve universal sewage treatment, drastically improving public health ratings
Águas Guariroba, an Aegea utility responsible for supplying basic sanitation services in Campo Grande, invested approximately R$ 800 million to expand and improve water and sewage services in the municipality. This investment was directed towards programs aimed mainly at making the sewage network universally available in all the city’s districts.
Sewage was one of the greatest challenges in the capital of Mato Grosso: It was available to only 18.72% of the population. With this in mind, in 2006 Águas Guariroba implemented the largest investment in sewage works in the city’s history: the Sanear Morena Program.
In stages, the program reduced hospitalization rates for diarrheal diseases in 2013, down 85.89% compared with 2003, when most of the population did not have access to sanitation. Diarrhea is a common symptom for many diseases related to inadequate sanitation.
The Sanear Morena Program
Launched in 2006, the first stage of Sanear Morena was a landmark in the capital’s basic sanitation. In just three years Águas Guariroba invested in construction works that doubled the sewage network of Campo Grande, providing sewage collection and treatment for 60% of the population in 2008.
In 2010, Águas Guariroba started the second phase of the program, continuing expansion of the city’s system. In 2013, with the completion of this phase, 73% of the capital’s population enjoyed sewage collection and treatment.
With the third stage of the program currently under way, Campo Grande should be one of the first Brazilian capitals to offer universal sewage treatment. At this stage, there are plans to invest R$ 636 million to offer basic sanitation throughout the capital. The program intends to universalize basic sanitation throughout the city by 2025.
Sewage treatment and its impacts
Universal basic sanitation offers immediate benefits for the health of the local population. Data from DATASUS (Unified Health System ‘SUS’ Information Technology Department) and the IBGE indicate that in 2003, diarrhea admissions were 157.4 per 100,000 inhabitants. By 2013, the number dropped to 22.2 per 100,000 inhabitants. There was also a steady reduction in SUS spending on admissions for this type of illness during the same period: from R$ 48,336.37 per 100 thousand inhabitants in 2003 to R$ 10,618.12 in 2013 – a 78.04% reduction.
In addition to improving public health ratings, the sewage system expansion also protects the environment. Rivers, streams and groundwater reserves are free from untreated sewage contamination.
Today, all sewage collected is treated before it is released into the streams and Campo Grande has two sewage treatment plants: ETE Los Angeles and ETE Imbirussu.
Water treatment in Campo Grande
When Águas Guariroba began work in Campo Grande, water supplies were not universally available: it only reached 96% of the population. Today, the treated water supply reaches 99.7% of the population – 853 thousand inhabitants (IBGE 2015). The company has a water quality monitoring laboratory where bacteriological, physical and chemical tests are carried out daily on samples collected in various parts of the city. The work guarantees treated water complies the guidelines of Ministry of Health Ordinance 2.914/11.
Today, the Campo Grande water supply system is ready to produce 30% more water than the city requires, which guarantees water security even in periods of drought and heat.
