Start of design for renovation of De Drie Delfzijlen pumping station
To continue ensuring water safety, Noorderzijlvest Water Authority is Noorderzijlvest Water Authority with Stork and Aveco de Bondt on plans to make the pumping station Drie Delfzijlen pumping station future-proof. Among other things, this involves replacing the diesel engines with electric motors. The project also pumping station the replacement of the pumping station entire electrical system. The Final Design will be ready by the end of 2023, after which the necessary work will begin in 2024.
Water drainage
The pumping station Drie Delfzijlen pumping station discharges excess surface water from the Damsterdiep into the sea. This water is discharged from the Damsterdiep through discharge pipes into the pumping station , relying on natural flow pumping station much as possible. This is only possible when the water level in the Eems is lower than that in the Damsterdiep. In addition, the pumping station has pumping station pump units, which together can discharge a maximum of 1,500 m³ of water per minute. The pumps ensure that excess water is discharged into the Eems when the water level in the Eems is higher than the water level in the Damsterdiep.
Renovation plans
To ensure that water can continue to be discharged in the future, renovation of the pumping station is pumping station . Several components have reached the end of their technical service life. These must be replaced to keep the pumping station operating pumping station . Following an initial feasibility study, the water authority, Stork b.v., and Aveco de Bondt have formed a construction team to pumping station the plans for the pumping station a Final Design. The plans focus on replacing the entire electrical system of the pumping station replacing the two diesel engines with electric motors. The endeavour to complete the electrical installation and the conversion of the first pump in the first half of 2024. The second pump will be converted in the summer of 2025. In addition, major maintenance on the pump impellers is necessary. Unnecessary piping and components will also be removed, and modifications to floors and other building-related facilities are planned.
Credit
In 2022, the water authority the exploratory phase for the renovation. During this phase, the scope of the project to realise a future-proof pumping station was pumping station . Following the completion of this exploratory phase, the Board of Directors Noorderzijlvest approved funding for the project in February 2023.
