The construction process of a water well involves the laying of screens and tubes for filter pack.

Paparelli is a company that produces screens and tubes for water wells, particularly Johnson filter type, frequently used in the development of water well.

Screens are important for the primary function they perform: prevent the penetration of sediment in the well.

Infact, the Johnson screens type which occupies Paparelli have the purpose to block the infiltration of grit which cause reductions of the flow capacity, and an error of the screen in the production area could result in the loss of the well.

Furthermore, screens support of earth formations not solidified, allowing at the same time the development of the structure and minimizing clogging.

The Paparelli company has been concerned for 50 years of screens and tubes for water wells, realizing works at international level and partecipating in the construction of water wells in different parts of the world, as in one of the last workings in the case history.

Thanks to their opening, the Johnson screens type are capable of retaining 90% of the gravel and this is dimensioned according to the granulometry of the ground.
