Sustainability, Materials, and Quality
The tanks are made of durable, fully recyclable polyethylene (PE). Some of the material used comes from our own recycling program. The durable construction saves resources and enables environmentally friendly use for many years.
The material used is environmentally friendly and chemically inert. It has no effect on the quality of the stored water. The production and recycling of plastic containers are relatively resource-efficient and support a responsible, future-oriented circular economy.
Notes
Please follow the installation instructions. Read the instructions carefully and in their entirety before installation, connection, and commissioning, and observe all safety instructions. This is the only way to ensure safe and proper operation.
Improper installation or failure to follow the instructions may void warranty and guarantee claims, particularly if the defect is attributable to faulty installation.
For round tanks, the installation pit is generally made deeper rather than wider. If groundwater or stratum water is present, appropriate protective measures are required. Alternatively, the use of flat tanks may be advisable.
