Due to the dismantling of a defective digester, liquid sewage sludge currently has to be transported from the Solingen-Ohligs sewage treatment plant to other sewage treatment plants by means of a drum truck for treatment. In some cases, these transports also have to transport sewage sludge for dewatering at the Solingen-Ohligs sewage treatment plant or centrate water for treatment at the Solingen-Ohligs sewage treatment plant back to the Solingen-Ohligs sewage treatment plant.
