The „Neustädter Klärbecken“
On November 26, 1903 in Neustadt an der Haardt the Wasser- und Abwasserreinigung GmbH, a subsidiary, was founded which successfully dealt with the design and construction of sewage treatment plants. An increasing industrialisation required industrial sewage water to be treated before allowing it enter the public canalisation network. The settling basins were constructed of reinforced concrete and because of the company’s own patents it was in a position to supply the required logistics for the treatment, too.
In the so-called „Neustädter Doppelbecken“ (Neustadt double basin) there were separate chambers for water and mud. The mud that settled in the septic tanks was transported to drained slag beds after three to five months where it could dry and then be cut for further use, for example as soil fill.
The Neustadt settling basin was not only used in municipalities, but also in numerous industrial plants both at home and abroad. Companies in the furnace industry, mining companies and steel mills, coal washing plants and plants in paper, pulp and leather industries were the main clients.
