Technical approval process for large dimensions non-standardized reinforced sewage elements

The aim of this paper is to present the experi-mental research carried out in order to ensure compliance with the EU law, when placing on the construction market elements larger than those framed in the harmonized European standard. The research methodology followed experimental testing components of the rein-forced concrete type manholes with an inner circular section whose nominal dimensions exceed DN 1250. An important issue for local communities has been collecting household waste water, industrial wastewater and rainwa-ter and treating them to be carried back to wa-tercourses. By building sewage systems and providing drinking water supply will protect the population against the negative effects of the wastewater over the human health and the environment.
