Sparkling fresh, clear water straight from the mountains - is what 107,000 inhabitants of Bolanzo (Italy) enjoy daily. Bolzano trusts in quality from Austria to ensure a safe and reliable drinking water supply.

In the course of connecting the Bolzano general hospital to the district heating plant, all water supply lines were renewed by the local construction company Rottensteiner vom Ritten. Together with cast iron pipes from TRM (Tiroler Rohre GmbH), Hawle products from Austria and Poland were installed.

In the smaller dimensions DN 250 and DN 300 Hawle E1 Gate Valves were installed whereas in the bigger dimensions the customer decided to use Hawle E2 Gate Valves PN 16. The flanged T-pieces with the integrated Gate Valves were assembled outside of the trench prior to the installation. Due to this a quick installation on site was enabled.

Bigger Hawle Gate Valves (from DN250) are equipped with eyebolts as standard for easy handling. The epoxy powder coating (according to GSK) ensures the usual quality expected by Hawle. That's why all our products are corrosion-free and have a lifespan of more than 50 years to ensure safe and healthy drinking water for the Bolzano inhabitants.

According to the strict water protection right in Bolzano (water protection area C), strict conditions are prescribed for construction work on drinking water pipes. Therefore, with experienced companies and high-quality products, groundwater pollution is prevented, and the permanent drinking water supply of the population is ensured.
