Framework contract for the supply of ESF compact systems 2023-2025

Delivery of approx. 100 pieces of wastewater collection shafts (ESF compact systems) for pressure drainage. It is possible to supply shafts made of polypropylene (PP) and polyethylene (PE-HD) for duo systems. The shafts must meet the requirements/material characteristics of Hamburg's AöR (HSE) city drainage system according to ZTV siele. The ESF systems are to be delivered ready for connection as mono systems (1 pump) with a diameter of 1 m and as a duo system (2 pumps) with a diameter of 1.50 m in different lengths according to design drawings with complete technical equipment (Jung pump, fittings, pipes, float switches, potential equalization, etc.). Ancillary offers are not permitted, as all around 9000 existing systems are equipped with identical installations to ensure economical maintenance and in particular to quickly rectify faults.
