70 meters long chain scrapers to Trondheim


In October, the first installation of Hydria Water’s delivery of chain scrapers to the Ladehammeren RA waste water treatment plant in Trondheim.

Ladehammeren is the largest waste water treatment plant in Trondheim, located in the mountain, and is designed for 120,000 pe. Hydria Water has delivered four chain scrapers that are 70 meters long, and 7 meters wide, and the last installation is carried out this spring. The total order value is just over 2.6 million SEK.

-At the same time as our installation, renovation of the surface layers in all the tanks is ongoing. Because the waste water treatment plant is in full operation, only one tank at a time is available for renovation, therefore it will take about 12 weeks between each installation, explains Philip Carlsson, sales engineer at Hydria Water, and continues:

“We have not delivered to Trondheim municipality earlier and it is exciting that we got the confidence to do it this time. It will be a good reference facility for us in the Norwegian market in the future.

VA Teknik Sweden expands


VA Teknik Sweden has had a record high autumn and recruited both a new design engineer, two new recruits to the workshop and a production technician, while still had to use temporary personnel and work overtime to keep up with the market.

-As our order intake has increased we have also accelerated during and after the summer. There are many aspects that come into play, like the sales work within Hydria Water, but a large part is also our project manager Jens Lingman that could relieve sellers with several tasks, which means that they have more time to sales meetings and client visits, explains Martin Jingnäs, CEO of VA Teknik Sweden.

In the autumn, VA Teknik Sweden have invested in several new welding machines to our workshop and made an internal relocation in our warehouse to free production area to be doubled in size.
