On the weekend of September 27. and 28. July 2019 reached via the wastewater treatment plant (WWTP) Ergolz 2 in Füllinsdorf, a larger quantity of waste water unpurified in the Ergolz. The previous investigations have shown that this introduction was presumably the result of a faulty operation of the control system, as well as the high amounts of precipitation. We did not observe any injury to persons or damage to the environment.

A presumed faulty operation of the plant had the consequence that Unger was passed to give effect to a waste water not to the ARA, but in the mixed water pool in front of the ARA. The mixed pools of water serve in the case of high rain intensity for the intermediate storage of waste water. The collected mixed water is treated to rain at the end of the ARA. In the event of high rainfall on the weekend of September 27. and 28. July 2019 were the mixed water pool with the misguided waste water filled. This wastewater was relieved because of the rain in the Ergolz. Overall, the office for Industrial establishments (AIB) is an amount of 14`000 cubic meters.

Because of the rainfall, the water has risen to leadership of the Ergolz solid. Therefore, the was initiated, unpurified waste water are highly diluted. In the case of a control of the body of water 29. July 2019 were found to be no damage. Endanger the safety of persons on the basis of this introduction can be excluded.

Due to the incident, the office for industrial establishments (AIB) in the construction and environmental protection Directorate reviewed the processes and procedures. The office for the protection of the environment and energy (AUE) as a Supervisory authority, submit in the next few days a complaint against unknown because of water pollution at the Prosecutor’s office of Basel-Landschaft.
