The materials listed in the standard for tanks of small wastewater treatment plants are varied as the possible treatment processes themselves. The materials allowed range from classic reinforced concrete, via fibre-reinforced plastics through to stainless steel.
All materials, or containers and tanks manufactured from them, have to prove their suitability in terms of their intended use. In addition to tests for structural behaviour and water tightness, there are also the proof of reaction to fire, durability and a leaching test to verify if any dangerous substances are present.
PIA GmbH has partners and co-operative bodies throughout Europe and can provide the appropriate material tests and the required expertise, wherever needed.
