The existing grotto and sandpit building is built in 1990. The building is not in an emergency condition, but the equipment is already worn out and does not ensure the efficient use of the equipment. As part of the general structural (building) repair works, the existing worn sand and grease removal bridges were replaced along with the existing scrapers, new sand and grease removal scrapers, and the existing grit tanks were covered. After installing the covers, a ventilation system was installed, which is connected to the existing system with a biological cleaning filter.  After installing sand pit covers, the smell emitted by the sewage treatment plant has significantly decreased.

All planned works were completed in August 2024.
