Pipe Relining DN 800 in Trieste

Beside the wonderful Piazza Ponterosso in Trieste, Ris.Fo. SPA relined a DN 800 waste water pipe with No-Dig technolgy and low enviromental impact. Since the groundwater is quite like the sea level, we use felt-liner with epoxy resin inverted by water column. Ris.Fo SPA even prepares the BY PASS using a supersilent 120 kW power generator and water pumps, calculated in order to pump all the maximum water flow on the working pipe.
