Proposta de sistema de esgotamento sanitário para a cidade de lagoa – PB.

Abstract

Sanitary Sewage Systems in Brazil are currently in a precarious situation. Most cities in the country do not have an efficient system that collects, transports, treats and disposes of effluents in an environmentally correct manner. This negligence leads to a series of negative consequences for the environment and public health. The city of Lagoa-PB is one of many that has a high rate of unhealthy sewage, which can compromise the quality of water and soil due to these evictions, especially through rudimentary cesspools and open-air discharges. In the municipality under study, infant mortality rates and hospitalization due to diarrhea are very high. Thus, this work aims to minimize environmental damage and health problems in Lagoa through an efficient Sanitary Sewage System. The proposed project has a collection network that covers the entire urban area, consisting of 272 sections and a total of 17.78 km in length, two interceptors that border the natural water flows of the two river basins in which the city is located, a Sewage Treatment Plant of the Australian System type, suitable for the locality and a study of the location of the receiving body. The work followed the recommendations of the Brazilian legislation and renowned technical books in the area. In this way, all constituent parts met the required efficiency criteria. The networks will operate entirely by gravity and the treatment plant has reached an efficiency level above the recommended minimum.
