For years, a Russian waterworks in Kaliningrad was struggling with a leaking DN 900 water transmission pipe. After 5 years of ongoing repairs (and associated work and material costs) the waterworks decided to use a Nova Siria Duofit repair clamp in 2019. This choice of repair product not only provided a quick solution to the problem but allowed for considerable time and cost savings in future.

In order tofurther enable continuous water supply, the Kaliningrad waterworks has built up an "emergency stock" of such water supply fittings worth more than € 150,000.

Due to high product quality together with a long service life of products of the Hawle Austria Group, many waterworks have achieved considerable cost savings in 2019. The economic effect of such investments is long-lasting, as much less replacement or repair work will be required in future.
