Purpose of the drilling:

Well P 71 of TWL Ludwigshafen AG Renovation by over-drilling the DN 400 Rilsan - expansion piping and new filtering.

Renovation of the well Br. P 71 of TWL Ludwigshafen AG on a very cramped site. High effort for noise protection measures. Complete renovation of Br. P 71 by over-drilling the old wells - expansion pipework DN 400 Rilsan, drilling the borehole from 750 mm to 950 mm Ø and new filtering with DN 400 V4A/WDF - AR. Since Br. P 71 is in the flood area, a waterproof stainless steel shaft with a 3 m high standpipe was installed to accommodate electrical power.
