Alcochete Wastewater Treatment Plant

2005

PECS was responsible for the structural and foundation projects and some specialties of the Wastewater Treatment Plant (WWTP) in Alcochete.

 

In addition to the development of the projects, he was also responsible for their coordination and for monitoring the respective administrative licenses.

 

The Treatment Station includes several buildings and different organs.

Description

Given that this treatment infrastructure is founded in a landfill area, where previously a lagoon treatment plant was located, there was a need to replace the foundation soil with a layer of Tout-venant with about 0.40m of thickness properly wrapped by geotextile blanket. The foundations proposed for the different bodies are either by means of piles molded “in situ”, with a diameter of 0.40m, or by means of shoes directly on the foundation ground, when the elevation of this one presents soils with acceptable resistances (the permissible voltages vary between 75 and 150 kPa).

 

The various organs foreseen in the project will be in reinforced concrete, with walls with thickness ranging between 0.30 and 0.45 m. The foundations will have thicknesses ranging between 0.30 and 0.60 m in thickness. The buildings consist of reinforced concrete pillar / beam structures, with massive slabs of varying thickness between 0.20 and 0.25m. The building has five underground floors and a ground floor with coverage in specific areas. The excavation to be carried out has a plan area of approximately 3440 m2 and an average height of about 14.00 m, making a total volume of approximately 48 850 m3.
