Water is provided by the Basic Sanitation Company of the State of São Paulo (Sabesp) since 1977, providing tap water to 100% of the city, but serves only 93.47%–95% of the city with sewage collection. Águas de São Pedro had not a sewage treatment plant, so all the collected sewage (70,000 l/day, BOD/month) was not treated and flowed into the Araquá River, which is also one of the city's main water resources. The absence of a sewage treatment plant in the city has generated complaints from the population, questioning the responsibility of Sabesp in this problem. Other problematic cases such as water catchment, siltation, and environmental degradation have caused the mayor to consider not renewing the city's contract with the company. After several negotiations, the contract was renewed in May 2013. The first equipment for the construction of a sewage treatment plant arrived in November 2015, and the building was finished in 2016.
