TPAP Unité de Protection en Installations d'Eau Potable

The Protection of Drinking Water Training Unit, "TPAP", has been designed by EDIBON to study cases in which the drinking water system is contaminated with wastewater. It is specially designed for the training of students in the plumbing sector.

The Protection of Drinking Water Training Unit,"TPAP" simulates a drinking water system of a flour-floor house. The drinking water intake is located in the lowest floor (basement). Water is distributed from there, passes through an industrial meter, where the flow rate is registered, and is directed towards the six outlet valves that lead to three tanks made of PMMA.

The contamination of the drinking water is simulated by a possible pipe fracture or pressure drop, which would cause the backflow of wastewater to the drinking water pipe.

The unit includes: protection devices against wastewater backflow, pipe separators that guarantee that the water entering the system, at 1.5 bar approx., does not go back to the mains, backflow preventers that close the passage of the liquid flowing in one direction completely and allow the passage of the liquid in the other direction, pipe vents to remove air from the pipes, and two drain faucets.
