Unbeatable range: Different wastewater collection tanks with building authorities' approval

Wastewater collection tanks are the ideal solution for properties not linked to the sewer system which produce little or irregular amounts of wastewater. We provide these tanks in volumes of 1,000 l to 52,000 l. They are ideal for small gardens or weekend homes or as a temporary solution before being connected to the sewer system. GRAF collection tanks are easy to install due to their light inherent weight. Everything comes with DIBt approval.
