Dimensionamento de uma estação de tratamento de esgoto para o bairro Morada do Parque em Itapetinga - BA

Abstract

Basic sanitation, as defined by Law No. 14,026/2020, is crucial for human health, encompassing water, sewage, solid waste, and more. The lack of sewage collection and treatment leads to pollution and diseases, posing a challenge in Brazil, where only 55.8% have access to collection and 51.2% to treatment, with even worse figures in the Northeast. Objective liability was applied, resulting in the installation of domestic treatment systems. Fiberglass and resins, known as FRP (Fiber Reinforced Plastic), emerged as a more efficient and cost-effective solution. The Regulatory Framework for Basic Sanitation aims to improve service access, with the goal of universalization by 2033. New sustainable projects are needed to address deficiencies and promote equal access. The study proposes a solution for domestic sewage treatment in the Morada do Parque development in Itapetinga, Bahia, with 1,498 inhabitants. The choice was the extended aeration activated sludge method with intermittent flow, due to its constructive and operational advantages.
