# Maintenance of three CHP modules at Kassel wastewater treatment plant

KASSELWASSER seeks maintenance work on three combined heat and power modules at the Kassel wastewater treatment plant for 2027 and 2028. The available notice identifies the equipment count, facility and service years, but gives no maintenance intervals, technical condition, service levels, value or award criteria. Offers are due 22 October 2026 at 07:00 UTC. The official detail page timed out during bounded access attempts, so additional technical requirements remain unknown.
