For a long time, water management in Belo Horizonte focused on keeping up with population growth, in many respects with success. The drinking water supply system connects 99.7% of Belo Horizonte residents (Nascimento et al, 2007) and is operating to high standards in terms of reliability of service and water quality. Coverage by sewerage systems is also high, reaching about 92% of the population (idem). However, 40% of the interceptors that transport household wastewater to treatment stations without entering the urban drainage system still need to be constructed. This lack is an important cause of seepage of sewage into groundwater, and subsequently into streams. In addition, there are many illegal connections to the separate stormwater drains, mostly from households but possibly also from industrial premises. Coverage of sewerage systems in the neighbouring municipalities is also much lower than in the city. This means that a considerable amount of wastewater still ends up in stormwater drains and rivers.
