I was asked to provide a detailed explanation for the delay. I did so and uploaded a letter with several attachments, e.g. emails from the wastewater management company (due to the massive delay in the development) on the BAFA page before the end of last year. About a week ago, I only received a kind of acknowledgment of receipt. It stated that the documents had been received, were with the specialist department, and were being reviewed, but as usual, due to high workload, it might still take some time. But now that the pump has finally been delivered and everything is running smoothly, I will barely manage to complete the implementation within the already approved period.
