Renovation of drinking water pipes

starline®1000

The starline®1000 process is used for the trenchless rehabilitation of underground drinking water supply and transport pipes using fabric hose relining and is designed for a normal operating pressure of up to 10 bar in the distribution system. In fabric hose relining, the old pipeline is lined with an ageing-resistant fabric hose. With the starline®1000 method, a mobile rehabilitation unit that is independent of the rehabilitation vehicle also enables rehabilitation in areas that are not directly accessible to trucks. The dimensions of the pipeline are retained. Under these conditions, the service life of the rehabilitated pipeline is comparable to that of a new PE pipeline. New connections can be easily connected using a tapping device and backflow-proof using conventional construction methods. The fabric hose and adhesive meet the necessary hygiene requirements in accordance with the KTW recommendation/UBA guideline for drinking water compatibility and DVGW worksheet W 270 with regard to microbiological properties.

starline®HPL-W for drinking water transport pipes

The starline®HPL-W processis used for the rehabilitation of drinking water transportation and long-distance pipelines. The fabric hose and adhesive are tested for pipe diameters from DN 100 to DN 600 and operating pressures up to max. 40 bar. Processing times of up to eight hours enable very long rehabilitation sections. Curing takes place without the addition of heat. At the heart of the starline®HPL special technologyis the self-propelled pressure drum on caterpillar tracks, which is suitable for unpaved terrain and high-quality surfaces. Beforehand, the defined quantity of adhesive is evenly distributed in the fabric hose in the air-conditioned application container. Depending on the dimensions, rehabilitation lengths of up to 600 m are possible. As only small cleaning pits are required at a maximum distance of 180 m, less than 10% earthworks are required. Existing and future corrosion breakthroughs up to 50 mm in diameter are eliminated efficiently, quickly and permanently with this process and operational safety and drinking water hygiene are restored in the long term. In addition, in future it will be possible to drill through with standard tools without any problems.
