Received an order for four Fish Friendly Pumps for Yuen Long Barrage Pumping Station, Drainage Services Department, the Government of the Hong Kong Special Administrative Region [Orders Received in October 2024]

Torishima (Hong Kong) Limited, a consolidated subsidiary of Torishima, has received an order for four Fish Friendly Pumps (FFP), which will be delivered to the Yuen Long Barrage Pumping Station, currently under construction in the Yuen Long City for the Drainage Services Department (DSD), the Government of the Hong Kong Special Administrative Region, which manages rivers and sewers in Hong Kong.

In recent years, there has been a growing trend, especially in Europe, to replace drainage pumps with FFPs to prevent eels and other fish in rivers from being sucked in and killed. In response to these needs, Torishima has developed FFP and received its first order.

The basic structure of the pump is the same as that of a normal vertical mixed-flow pump, but the following innovations are incorporated to improve fish survival rates.

・Reduced number of impeller blades
・Rounded impeller tips and increased thickness
・Lower rotation speeds

When DSD considered introducing FFP to demonstrate its commitment to the environment and aquatic life, it initially planned to use the FFP from another company instead of Torishima’s. However, Torishima had earned DSD’s trust based on its extensive track record of deliveries and construction projects. By actively making technical proposals and presentations to carefully explain the advantages of Torishima’s FFP, DSD decided to adopt it.

In addition to our FFP, the largest-diameter pump in Torishima’s history is also scheduled to be delivered to the pumping station. The construction of the pumping station, designed to be friendly for both residents in the surrounding area and fish in the water, is progressing steadily and is scheduled for completion in 2027.
