1. Evaluation of the gradient precision of the horizontal directional drilling technique for the installation of gravity sewers / Avaliação da precisão da declividade da técnica de perfuração direcional horizontal para instalações de redes de esgoto
The present work is focused on the horizontal directional drilling (HDD) method to install gravity sewers. The results of different techniques are described intending to meet the demands of gradient. Therefore, 4 experimental pilot bores were drilled simulating a section of those structures extending 30 m with HDPE pipelines of 125 mm external diameter. Thos

2. Effects of the accepting water treatment plants (WTP) residuals at wastewater treatment plant (WWTP) using SBR activated-sludge process with extended aeration in the city of Juquitiba, SP. / Efeitos do recebimento do lodo da estação de tratamento de água pelo sistema de tratamento de esgoto por lodo ativado em bateladas e aeração prolongada do município de Juquitiba - SP.
There are different technical engineering solutions for the treatment and final disposal of water treatment plants (WTPs) residuals. Discharge of WTP residual to a wastewater treatment plant (WWTP) is a technical solution in evidence. Therefore, the purpose of this study was to evaluate the capacity of the WWTP using sequencing batch reactor (SBR) activated-
