The tanks of DELPHIN® wastewater treatment plants are built from high quality, rod resistant polyethylene. In order to ensure the virtually indefinite life span of the material, professional handling and installation underground or aboveground is mandatory.
For the construction of our tanks, we count on mondern 3D construction softwasre with finite element method (FEM) in combination with years of experience in the field. In consequence, DELPHIN® tanks are extremely robust and unparaleled in the field of wastewater treatment. On the test field, they proofed their stability even in deep pits and high groundwater levels.
According to European norm, a volume reduction of 20% is admissable for underground tanks. We believe that is too much. Therefore, we developped tanks with less volume reduction even under extreme circumstances. The proven maximum volume reduction at maximum load of our DELPHIN® compact tank of only 5.2% ensures the long term functionality of all installed equipment and the sludge storage volume.
